An Anthropocene Journey - Andrew C. Revkin

An Anthropocene Journey - Andrew C. Revkin | PLASTICITIES  « Between matter and form, between experience and consciousness, the active plasticity of the world » | Scoop.it
I imagine you’ve heard some of the competing words that have bubbled up. We’re actually in the greed-driven Capitalocene, the trash-choked Plasticene, the combustible Pyrocene, the self-loathing Misanthropocene, the testosterone-dominated Manthropocene—even the Obscene. There’s some merit as well as weakness in every label, including the word that sparked it all.

The anthropocene (both the word and the unfolding age) has so much Rorschach-like plasticity that all I can offer as guidance are my informed but subjective reflections based on what I’ve learned and unlearned in my long, quirky journey. I’d argue that what matters most is not resolving some common meaning so much as engaging in deeply felt discussions, fresh lines of inquiry, and new proposals for sustaining the human journey—all of which have been sparked by the emergence of this concept.

Remodeling myelination: implications for mechanisms of neural plasticity

Remodeling myelination: implications for mechanisms of neural plasticity | PLASTICITIES  « Between matter and form, between experience and consciousness, the active plasticity of the world » | Scoop.it
Abstract

One of the most significant paradigm shifts in membrane remodeling is the emerging view that membrane transformation is not exclusively controlled by cytoskeletal rearrangement, but also by biophysical constraints, adhesive forces, membrane curvature and compaction. One of the most exquisite examples of membrane remodeling is myelination. The advent of myelin was instrumental in advancing the nervous system during vertebrate evolution. With more rapid and efficient communication between neurons, faster and more complex computations could be performed in a given time and space. Our knowledge of how myelin-forming oligodendrocytes select and wrap axons has been limited by insufficient spatial and temporal resolution. By virtue of recent technological advances, progress has clarified longstanding controversies in the field. Here we review insights into myelination, from target selection to axon wrapping and membrane compaction, and discuss how understanding these processes has unexpectedly opened new avenues of insight into myelination-centered mechanisms of neural plasticity.

New Phytologist: Towards a holistic understanding of the beneficial interactions across the Populus microbiome

New Phytologist: Towards a holistic understanding of the beneficial interactions across the Populus microbiome | PLASTICITIES  « Between matter and form, between experience and consciousness, the active plasticity of the world » | Scoop.it

Interactions between trees and microorganisms are tremendously complex and the multispecies networks resulting from these associations have consequences for plant growth and productivity. However, a more holistic view is needed to better understand trees as ecosystems and superorganisms, where many interacting species contribute to the overall stability of the system. While much progress has been made on microbial communities associated with individual tree niches and the molecular interactions between model symbiotic partners, there is still a lack of knowledge of the multi-component interactions necessary for holistic ecosystem-level understanding. We review recent studies in Populus to emphasize the importance of such holistic efforts across the leaf, stem and rooting zones, and discuss prospects for future research in these important ecosystems.

Frontiers: Epigenetic Mechanisms and Microbiota as a Toolbox for Plant Phenotypic Adjustment to Environment

Frontiers: Epigenetic Mechanisms and Microbiota as a Toolbox for Plant Phenotypic Adjustment to Environment | PLASTICITIES  « Between matter and form, between experience and consciousness, the active plasticity of the world » | Scoop.it
The classic understanding of organisms focuses on genes as the main source of species evolution and diversification. The recent concept of genetic accommodation questions this gene centric view by emphasizing the importance of phenotypic plasticity on evolutionary trajectories. Recent discoveries on epigenetics and symbiotic microbiota demonstrated their deep impact on plant survival, adaptation and evolution thus suggesting a novel comprehension of the plant phenotype. In addition, interplays between these two phenomena controlling plant plasticity can be suggested. Because epigenetic and plant-associated (micro-) organisms are both key sources of phenotypic variation allowing environmental adjustments, we argue that they must be considered in terms of evolution. This 'non-conventional' set of mediators of phenotypic variation can be seen as a toolbox for plant adaptation to environment over short, medium and long time-scales.

Understanding and exploiting plant beneficial microbes

Understanding and exploiting plant beneficial microbes | PLASTICITIES  « Between matter and form, between experience and consciousness, the active plasticity of the world » | Scoop.it
After a century of incremental research, technological advances, coupled with a need for sustainable crop yield increases, have reinvigorated the study of beneficial plant–microbe interactions with attention focused on how microbiomes alter plant phenotypes. We review recent advances in plant microbiome research, and describe potential applications for increasing crop productivity. The phylogenetic diversity of plant microbiomes is increasingly well characterized, and their functional diversity is becoming more accessible. Large culture collections are available for controlled experimentation, with more to come. Genetic resources are being brought to bear on questions of microbiome function. We expect that microbial amendments of varying complexities will expose rules governing beneficial plant–microbe interactions contributing to plant growth promotion and disease resistance, enabling more sustainable agriculture.

Is nature “natural” anymore? - Mapping Ignorance (2015)

Is nature “natural” anymore? - Mapping Ignorance (2015) | PLASTICITIES  « Between matter and form, between experience and consciousness, the active plasticity of the world » | Scoop.it

It seems that we are definitely heading towards the bio-based society, a new way of interacting with the environment where fossil fuels won’t be needed anymore and “more natural” processes for producing energy, food and materials will prevail. Remarkably, this bio-turn often involves highly advanced biotechnology and strict competitive targets, both facts that challenge our general understanding of what a “more natural way of doing things” is. Politicians, scientists, and companies are well aware of this apparent contradiction but, are they willing to clarify the meaning of this tricky jargon (naturalness, sustainability, circularity…) within the so-called Bio-based Economy? ... 

Anyone with an eye on marketing and communication techniques knows that concepts such as natural, green, sustainable... are at risk of being emptied of meaning and then populated with vague content coming mostly from commercial interests. These terms are often used in a rhetorical rather than in a scientific fashion, leading to a sometimes deliberate misunderstanding and a subsequent distrust among the general public. As a result, the latest advances in biotechnology, as well as their impact on the environment in the mid-term, remain buried in this conceptual confusion, where we are not quite sure whether nature still is what we were used to thinking it was.

The fact is that people tend to have an Aristotelian concept of nature, that is, we usually conceive nature as everything that exists without human intervention. That’s why we are quite a skeptic about considering as “natural” those processes involving sophisticated technology and the modification of the building blocks of living systems. Traditionally, we have considered nature and technology as opposites... Yet nature is now presented in a different way. Biotechnology experts interpret their intervention in nature as an act of mimicry... scientists learn about the tools and methods that nature has been using to evolve... and then they replicate this knowledge in order to go one step further. 

This is the subject of a recent publication... They emphasize the need for a critical assessment of the content of all these concepts related to the upcoming Bio-based Economy, and they choose the term nature as an important example of an evolving concept that has been subjected to constant modification throughout history in parallel to the development of human culture, science, and technology. So the question is: what is nature for us now, in the era of biotechnology and genetic engineering? ... 

Biotechnology has carried out an outstanding scrutiny of nature and living systems in the last few decades. We have achieved an impressive knowledge of how nature works at the molecular level and how we can use that knowledge to give outcomes inconceivable some years ago in the fields of agriculture, medicine or industry. Life scientists have conquered the “molecular plasticity of nature”... and they are willing to improve and optimize its performance. But, are nature mechanisms something to be improved or optimized? ... 


There is the technical way of viewing nature... technology is not a stranger to nature, but the other way around. Nature is an immense laboratory, a biotechnological phenomenon, and we use its own methods as mere plagiarists. Advocates of this position don’t find a difference between the natural and the non-natural at the molecular level and, at the end of the day, human beings, as part of this nature, have their right to own its “know-how” and use it for their own good. Fair enough. Moreover, the promise of less disruptive technologies and the end of the fossil-fuel era give us reasons for optimism.

But on the other hand, there are those who claim that this new bio-based turn is nothing but a new chapter in the story of the industrialized world taking control over nature; an act of avoidance instead of criticism towards the alarming attitude of exploitation and consumerism of recent times. These voices find that behind this purpose of reprogramming nature to achieve a more natural world, there is a powerful tool for industry to continue its large-scale exploitation of natural resources...

Pour une méthodologie de la transformation.              Au croisement de la somatique et                         de la technologie: pour devenir autre… | PLASTICITIES  « Between matter and form, between experience and consciousness, the active plasticity of the world » | Scoop.it

La suprématie du discours de l’interface est le discours dominant de la scène performative contemporaine : celle qui intègre les technologies. Ce discours est basé sur la vision dualiste et matérialiste du monde occidental, sur une culture de l’objet tel que l’a identifié Christine Buci-Glucksmann (2003). J’expliquerai, dans la section sur la méthodologie, comment le développement d’une pensée intégrative est nécessaire pour sortir de ces pièges réductionnistes ainsi que pour investir les enjeux de la corporéité. L’approche de l’interface, telle que conçue dans le domaine des arts visuels, a donc été majoritairement importée dans le milieu des arts vivants performatifs.

 

La conception traditionnelle de l’interface qui se situe au croisement entre le technologique et l’humain, formalise une pragmatique communicationnelle dont le but est de traduire et de transformer le corps-langage humain et le langage-calcul de l’ordinateur écrit Emanuel Quinz, qui fait son analyse d’un point de vue des arts visuels et médiatiques, même si toute une évolution du concept d’interface prend place par la suite, il reste que même si le concept de l’interface artificielle se raffine, il fonctionne encore sur des principes de sélection et de réduction, en contrepoint avec le corps qui est comparé à une interface physiologique hyper complexe...

Phenotypic Plasticity

For more than two decades the concept of phenotypic plasticity has allowed researchers to go beyond the nature-nurture dichotomy to gain deeper insights into how organisms are shaped by the interaction of genetic and ecological factors. Phenotypic Plasticity: Beyond Nature and Nurture is the first work to synthesize the burgeoning area of plasticity studies, providing a conceptual overview as well as a technical treatment of its major components.Phenotypic plasticity integrates the insights of ecological genetics, developmental biology, and evolutionary theory. Plasticity research asks foundational questions about how living organisms are capable of variation in their genetic makeup and in their responses to environmental factors. For instance, how do novel adaptive phenotypes originate? How do organisms detect and respond to stressful environments? What is the balance between genetic or natural constraints (such as gravity) and natural selection? The author begins by defining phenotypic plasticity and detailing its history, including important experiments and methods of statistical and graphical analysis. He then provides extended examples of the molecular basis of plasticity, the plasticity of development, the ecology of plastic responses, and the role of costs and constraints in the evolution of plasticity. A brief epilogue looks at how plasticity studies shed light on the nature/nurture debate in the popular media. Phenotypic Plasticity: Beyond Nature and Nurture thoroughly reviews more than two decades of research, and thus will be of interest to both students and professionals in evolutionary biology, ecology, and genetics.

New Graphene Sensors Could Supply Unprecedented Insights right into Mind Structure

New Graphene Sensors Could Supply Unprecedented Insights right into Mind Structure | PLASTICITIES  « Between matter and form, between experience and consciousness, the active plasticity of the world » | Scoop.it

By M Fahad

Their extreme slimness enables nearly all light to go through across a wide variety of wavelengths. Placed on a flexible plastic backing that satisfies the shape of cells (bottom), the sensing units become part of a proof-of-concept device that demonstrates much smaller, transparent get in touches with that could measure as well as stimulate neural cells making use of electric and also optical techniques at the very same time (top right). New nanotechnology moneyed by DARPAs RE-NET program and created by scientists at the University of Wisconsin at Madison enables monitoring as well as excitement of nerve cells using optical and electronic methods simultaneously. Understanding the physiological structure as well as feature of the brain is a historical goal in neuroscience as well as a leading priority of President Obamas brain campaign. Electrical tracking as well as stimulation of neuronal signaling is a mainstay method for researching brain feature, while emerging optical techniques which use photons instead of electrons are opening up brand-new opportunities for envisioning semantic network framework as well as checking out brain functions. Electric and also optical strategies offer unique and also complementary benefits that, if made use of together, could provide extensive benefits for researching the mind at high resolution.

Incorporating these innovations is challenging, however, since standard steel electrode modern technologies are as well thick (> 500 nm) to be transparent to light, making them incompatible with many optical approaches.To aid conquer these difficulties, DARPA has actually created a proof-of-concept tool that shows a lot smaller, clear contacts that could determine and stimulate neural tissue making use of electrical and also optical techniques at the exact same time. Scientists at the College of Wisconsin at Madison developed the brand-new technology with support from DARPAsReliable Neural-Interface Technology (RE-NET). It is explained thoroughly in a paper in Nature Communications.

This innovation demonstrates possibly development capacities for visualizing and also measuring semantic network activity in the brain, claimed Doug Weber, DARPA program supervisor. The capacity to simultaneously measure electric task on a big and also quick scale with straight visualization and modulation of neuronal network anatomy might offer unmatched understanding right into partnerships between mind structure and also functionand notably, exactly how these connections progress in time or are annoyed by injury or disease.The brand-new gadget utilizes graphene, a lately found type of carbon, on an adaptable plastic support that conforms to the shape of cells. The graphene sensing units are electrically conductive but only 4 atoms thickless compared to 1 nano-meter and also thousands of times thinner than present calls.

Its severe slimness allows nearly all light to go through throughout a vast array of wavelengths. In addition, graphene is nontoxic to biological systems, a renovation over previous study into transparent electric contacts that are much thicker, stiff, difficult to make as well as reliant on potentially poisonous metal alloys.

The innovation demonstration brings into play three sophisticated research areas: graphene, which made researchers the 2010 Nobel Reward in Physics; super-resolved fluorescent microscopy, which earned researchers the 2014 Nobel Prize in Chemistry; and also optogenetics, which involves genetically modifying cells to create particular light-reactive proteins.RE-NET looks for to create brand-new devices as well as modern technologies to comprehend as well as get rid of the failing devices of neural user interfaces. DARPA has an interest in advancing next-generation neurotechnologies for exposing the partnership between neural network structure as well as feature. RE-NET, and also subsequent DARPA programs in this field, plan to utilize this brand-new device by simultaneously measuring the feature, physical motion and habits of nerve cells in freely removaling topics. This innovation gives the capacity to regulate neural function, by applying set pulses of electrical energy or light to temporarily turn on nerve cells.

It might not just give better monitoring of native performance yet also, through mindful inflection of circuit task, make it possible for exploration of causal partnerships between neural signals and brain function.Historically, scientists have actually been limited to correlational research studies that suggest, however do not confirm causal links between neural task and habits, Weber said. Now, we have the chance to directly see, gauge and also promote neural circuits to discover these partnerships and create and also validate versions of mind circuit function.

This knowledge could significantly aid just how we recognize and treat mind injury as well as disease.RE-NET is part of a wider profile of programs within DARPA that sustain Head of state Obamas brain initiative. These programs include recurring initiatives made to advance basic understanding of the minds dynamics to own applications (Transforming Prosthetics, Restorative Encoding Memory Combination Neural Gadget, Reorganization and also Plasticity to Speed up Injury Healing, Enabling Stress Resistance), manufacture picking up systems for neuroscience applications and therapies (Hand Proprioception & Touch Interfaces, Electric Prescriptions) and examine big data collections (Detection and Computational Evaluation of Psychological Signals).

Understanding the anatomical framework and function of the mind is a longstanding goal in neuroscience as well as a top priority of President Obamas brain effort.

Electric tracking and excitement of neuronal signaling is an essential technique for researching brain function, while arising optical techniqueswhich usage photons instead of electronsare opening brand-new possibilities for picturing neural network framework and also discovering brain functions. It is defined in information in a paper in Nature Communications.This innovation shows potentially innovation capabilities for envisioning and also measuring neural network task in the brain, claimed Doug Weber, DARPA program manager.

It might not just give much better monitoring of indigenous performance but additionally, through mindful modulation of circuit task, make it possible for exploration of causal connections in between neural signals and brain function.Historically, researchers have been restricted to correlational researches that suggest, however do not confirm causal affiliations between neural activity as well as habits, Weber stated.

PNAS: Live imaging of root–bacteria interactions in a microfluidics setup (2017)

PNAS: Live imaging of root–bacteria interactions in a microfluidics setup (2017) | PLASTICITIES  « Between matter and form, between experience and consciousness, the active plasticity of the world » | Scoop.it

Plant roots play a dominant role in shaping the rhizosphere, the environment in which interaction with diverse microorganisms occurs. Tracking the dynamics of root–microbe interactions at high spatial resolution is currently limited because of methodological intricacy. Here, we describe a microfluidics-based approach enabling direct imaging of root–bacteria interactions in real time. The microfluidic device, which we termed tracking root interactions system (TRIS), consists of nine independent chambers that can be monitored in parallel. The principal assay reported here monitors behavior of fluorescently labeled Bacillus subtilis as it colonizes the root of Arabidopsis thaliana within the TRIS device. Our results show a distinct chemotactic behavior of B. subtilis toward a particular root segment, which we identify as the root elongation zone, followed by rapid colonization of that same segment over the first 6 h of root–bacteria interaction. Using dual inoculation experiments, we further show active exclusion of Escherichia coli cells from the root surface after B. subtilis colonization, suggesting a possible protection mechanism against root pathogens. Furthermore, we assembled a double-channel TRIS device that allows simultaneous tracking of two root systems in one chamber and performed real-time monitoring of bacterial preference between WT and mutant root genotypes. Thus, the TRIS microfluidics device provides unique insights into the microscale microbial ecology of the complex root microenvironment and is, therefore, likely to enhance the current rate of discoveries in this momentous field of research.

Plant developmental evolution.

 

The relatively new field of plant evolutionary-developmental biology (‘evo-devo’) seeks to understand how and why plant morphological characters have evolved to produce the tremendous diversity of form in living plants. It draws from concepts and techniques of molecular biology, developmental biology, genetics, genomics, evolutionary biology and ecology, and attempts to synthesize principles from these disciplines to yield an understanding of how developmental systems respond to selection pressures for novel characters. It also seeks to characterize how evolution moulds complex traits, as well as the constraints that prevent such traits from reaching ‘optimal’ configurations. This meeting will draw together researchers in plant evo-devo for exchange of ideas, information about current research, and discussion of future directions for the field.  It will be organised into four sessions; three will be devoted to (1) floral development, (2) vegetative meristems, leaves, and inflorescences, and (3) plasticity and life history evo-devo and a fourth morning will be devoted to speakers who have been selected to give a talk following the submission of a poster abstract.  - See more at: https://www.newphytologist.org/symposia/37#sthash.lL8Vql5j.dpuf

Older Brain Is Willing, but Too Full for New Memories

Older Brain Is Willing, but Too Full for New Memories | PLASTICITIES  « Between matter and form, between experience and consciousness, the active plasticity of the world » | Scoop.it
Studies in modified mice suggest that it is harder to make new long-term memories as we age because the brain is full of old ones that are hard to erase.

 

The N-methyl-d-aspartate receptor (NMDAR) is widely known to be the synaptic coincidence detector essential for controlling synaptic plasticity and gating memory formation . Together with the NR1 core subunit, the NR2A and NR2B subunits form the diheteromeric or triheteromeric complex of the NMDA receptor in the forebrain regions. Depending on ages or states of animals, dynamic changes in NR2A and NR2B can lead to the different mixture of NR1/NR2A, NR1/NR2B, and NR1/NR2A/NR2B receptors in the forebrain. There is a higher amount of NR2B expression in postnatal and juvenile brains, but NR2A gradually becomes more prevalent in adulthood and advanced ages.

 

Based on distinct biophysical properties of the NR2A and NR2B (such as longer channel opening duration with the NR2B subunit than the NR2A, etc.), it has been hypothesized that an increased NR2A:NR2B ratio in the sexually matured and/or aged brains may represent a major genetic factor underlying the age-dependent, gradual constraint on memory functions in comparison to that of juvenile or younger brains. However, it is difficult to test this NR2A:NR2B ratio hypothesis by directly comparing the young animals with the aged animals because there are significant differences in expression of many other genes between those two age groups. Moreover, the levels of NR2A or NR2B expression in the cortex and hippocampus can also be dynamically modulated by individual experiences (i.e. enriched environment, or social interactions).

 

A series of genetic studies have shown that global knockout of NR2A resulted in lesser CA1 long-term potentiation, a moderate deficiency in spatial reference memory and fear memory, and/or significant spatial working memory deficit. This suggests that the presence of NR2B in NR2A−/− mice largely preserves LTP and most long-term memories. On the other hand, genetic deletion of NR2B in the forebrain- or hippocampus-specific knockout of NR2B results in more profound memory deficits and impaired LTP. These experiments, by examining the extreme ends of the NR2A:NR2B ratio spectrum (without NR2A or NR2B), have provided fundamental insights into the roles of the pure NR2A- or NR2B-containing NMDA receptor population under the given test conditions.

 

The initial evidence for the concept that an increased NR2A:NR2B ratio may reduce synaptic plasticity and memory function in adulthood came from NR2B transgenic experiments. Research has shown that genetic overexpression of NR2B in the mouse forebrain can lead to larger hippocampal long-term potentiation (10–100 Hz range, without affecting LTD) and enhanced learning and memory function as tested in seven different memory tasks. Similar memory and LTP enhancement was also observed in NR2B overexpression transgenic rats, pointing to the conserved beneficial effects of NR2B in multiple animal species. Thus, these NR2B overexpression experiments, along with other studies, have provided important evidence that the increased NR2A:NR2B ratio can be detrimental to greater synaptic plasticity and memory function in the older brains.

 

In a recent study, scientists have directly tested this hypothesis and investigated the effects of increased NR2A:NR2B ratio in the adult mouse forebrain on synaptic plasticity and learning behaviors by producing CaMKII promoter-driven NR2A transgenic mice. They combined hippocampal slice electrophysiology and behavioral paradigms to investigate how such overexpression may alter synaptic plasticity and cognition, and showed that the high NR2A amount in the forebrain principal excitatory neurons can selectively affect long-term memory formation. But surprisingly, instead of the predicted smaller LTP in the CA1 region of the NR2A transgenic mice, the researchers found that NR2A overexpression selectively abolished 3–5 Hz frequency-induced LTD in the CA3-CA1 synapses without affecting 100 Hz LTP or 1 Hz LTD.

 

This results suggest a novel step by which long-term memory consolidation engages LTD-like process to sculpt, crystallize, and incorporate newly acquired information into long-term knowledge in the brain.

Epigenetic Mechanisms and Microbiota as a Toolbox for Plant Phenotypic Adjustment to Environment

Epigenetic Mechanisms and Microbiota as a Toolbox for Plant Phenotypic Adjustment to Environment | PLASTICITIES  « Between matter and form, between experience and consciousness, the active plasticity of the world » | Scoop.it
The classic understanding of organisms focuses on genes as the main source of species evolution and diversification. The recent concept of genetic accommodation questions this gene centric view by emphasizing the importance of phenotypic plasticity on evolutionary trajectories. Recent discoveries on epigenetics and symbiotic microbiota demonstrated their deep impact on plant survival, adaptation and evolution thus suggesting a novel comprehension of the plant phenotype. In addition, interplays between these two phenomena controlling plant plasticity can be suggested. Because epigenetic and plant-associated (micro-) organisms are both key sources of phenotypic variation allowing environmental adjustments, we argue that they must be considered in terms of evolution. This ‘non-conventional’ set of mediators of phenotypic variation can be seen as a toolbox for plant adaptation to environment over short, medium and long time-scales.

Raconter notre vie paraît une des choses les plus ordinaires qui soient. Une expression de l’unique, dans le fait où chacun révèle son intime à sa manière. Par-delà nos différentes manières de travailler, nous considérons tous (peut-être à tort) que notre rôle se limite fondamentalement à dévoiler, recueillir et enregistrer des traces supposées être autant de bribes visibles d’une vérité cachée ou inaccessible de nos réels. Les circonstances de la réalisation de ces figures de révélation varient d’un spectateur à l’autre, d’un moment à un autre. Ces travaux personnels accompagnent les moments de crises de l’adolescence, ou encore des évènements mémorables. Cette pratique est ambivalente tant elle est une manière de confession ou d’exhibition, questionnement de Soi par Soi, dans une visée morale et thérapeutique.

 

Essayer de comprendre et rassembler la vie. Exprimer une colère, une faiblesse, une passion. Cela peut aussi être une intention de témoignage du quotidien. Comme objet d’étude, l’intime intéresse autant le sociologue, le psychologue, l’historien en littérature que celui des coutumes, et dernièrement beaucoup d’artistes, en raison de cet intérêt croissant pour la recherche à forme historique sur la vie quotidienne et ses représentations. Plusieurs formes existent au dévoilement de l’intime...

#Book - Torque#1. Mind, Language and Technology by Nathan Jones & Sam Skinner - free download | PLASTICITIES  « Between matter and form, between experience and consciousness, the active plasticity of the world » | Scoop.it

Torque brings together a diverse collection of essays and artworks, many newly commissioned for the project, that reflect upon the plasticity of the brain, the adaptability of technology and the malleability of language, and their twisting together through past, present and future cultures. The contributors and their work each offer unique models of navigating this territory, making their own artefacts, writing their own scripts, forging critical space and examining the blind spots.


Torque#1. Mind, Language and Technology is the result of a wide range of cross-disciplinary conversations, taking place across symposia, online forums, live events and workshops, produced by the book’s editors: Nathan Jones and Sam Skinner. According to Professor Mike Stubbs, Artistic Director at FACT Liverpool: “Torque activities and this publication bravely push our boundaries of cognition and thinking, through striking essays, tricky concepts, and beautiful, arresting imagery.”

Editorial: Plasticity in Multiple Sclerosis: From Molecular to System Level, from Adaptation to Maladaptation

 

The individual course of MS might not only be governed by neuroimmunological properties of the disease but also determined by the innate capacity of the CNS to overcome functional constraints related to MS pathology, i.e., by the patient’s individual resilience. Accordingly, variation in brain plasticity is believed to play a crucial role in explaining interindividual differences with respect to the clinical course as well as to discrepancies between functional impairment and magnetic resonance imaging (MRI) findings in patients with MS (3, 4).

 

Plasticity occurs at multiple levels in MS, from cells to synapses, from myelin to axons, from individual regions to large-scale brain networks [reviewed in Ref. (5)]. A growing body of evidence supports the notion that the course of MS and its extremely heterogeneous clinical manifestations might be the net result of disease burden and compensatory/reparative capacity. As a consequence, identifying what can be considered as “positive” plasticity and what, on the contrary, is a maladaptive reorganization is a very attractive goal that might help to develop therapeutic strategies able to promote the individual adaptive capacity.
