Fiala on ethics: Brain hackers raise social questions about learning ... Fresno Bee One might also worry that the learning that occurs through brain hacking doesn't really count. It seems like cheating.
We present an efficient approach to discriminate between typical and atypical brains from macroscopic neural dynamics recorded as magnetoencephalograms (MEG). Our approach is based on the fact that spontaneous brain activity can be accurately described with stochastic dynamics, as a multivariate Ornstein-Uhlenbeck process (mOUP). By fitting the data to a mOUP we obtain: 1) the functional connectivity matrix, corresponding to the drift operator, and 2) the traces of background stochastic activity (noise) driving the brain. We applied this method to investigate functional connectivity and background noise in juvenile patients (n = 9) with Asperger’s syndrome, a form of autism spectrum disorder (ASD), and compared them to age-matched juvenile control subjects (n = 10). Our analysis reveals significant alterations in both functional brain connectivity and background noise in ASD patients. The dominant connectivity change in ASD relative to control shows enhanced functional excitation from occipital to frontal areas along a parasagittal axis. Background noise in ASD patients is spatially correlated over wide areas, as opposed to control, where areas driven by correlated noise form smaller patches. An analysis of the spatial complexity reveals that it is significantly lower in ASD subjects. Although the detailed physiological mechanisms underlying these alterations cannot be determined from macroscopic brain recordings, we speculate that enhanced occipital-frontal excitation may result from changes in white matter density in ASD, as suggested in previous studies. We also venture that long-range spatial correlations in the background noise may result from less specificity (or more promiscuity) of thalamo-cortical projections. All the calculations involved in our analysis are highly efficient and outperform other algorithms to discriminate typical and atypical brains with a comparable level of accuracy. Altogether our results demonstrate a promising potential of our approach as an efficient biomarker for altered brain dynamics associated with a cognitive phenotype.

Learning is a dynamic function that each person experiences in a vastly different way. For instance, one individual may retain knowledge the best by studying a textbook while another may need to link an idea to a physical activity they perform.
Are explicit versus implicit learning mechanisms reflected in the brain as distinct neural structures, as previous research indicates, or are they distinguished by brain networks that involve overlapping systems with differential connectivity? In this functional MRI study we examined the neural correlates of explicit and implicit learning of artificial grammar sequences. Using effective connectivity analyses we found that brain networks of different connectivity underlie the two types of learning: while both processes involve activation in a set of cortical and subcortical structures, explicit learners engage a network that uses the insula as a key mediator whereas implicit learners evoke a direct frontal-striatal network. Individual differences in working memory also differentially impact the two types of sequence learning.
Scholars from Canada and Israel gathered to discuss research and challenges related to brain plasticity, learning and education. The topics ran the gamut from molecular neuroscience to behavioural psychology to education.
Critical thinking and analytical thinking are not the same thing. To clarify the difference between these words, let's look at their etymology (word origins). According to the dictionary, "analyze" means to break apart into essential elements. The opposite of analyze is synthesize, or put together. "Criticize" means to evaluate or make a judgment regarding the merits or faults. The opposite of criticize in one sense would be praise, or in another sense absence of judgment. Simply looking at the two definitions, it is glaringly obvious that two different skill sets are required. So why are they often lumped together? The dictionary definition of this answer would be a stupor of thought, or the condition of not thinking.
What happens when you tell your students to "pay attention!" More than you may think. This post explores what goes on in the brain and ways the brain pays attention. Research is shared as well as what you can do in your classroom immediately as well what you can do in the long term. Short term solutions include "using prediction; using the brief pause and chunk technique; priming the learning with small hints, appetizers and teasers" and more.
I recently partook in a discussion among some fellow community managers on the best ways to learn about the industry and how to train its future generations. When the conversation reached the point where we all shared the “training” we went through ourselves, the answers began getting interesting.
“I studied marketing in college.”
“I studied communications and the art of rhetoric.”
“The job I’ve had that contributed most to the development of my community management skills was being a community manager.”
“My social life and interactions with others have been one of the biggest contributors to my professional skill set.”
It’s no secret that there just isn’t a degree to be earned in social media or community management. In fact, I graduated college one short year ago, and never even knew that this extensive professional field existed until I was thrown into it.
The reality is, this isn’t only the case for community management. It’s the case for SEO. It’s the case for entrepreneurship. It’s the case for social advertising and Internet marketing. We’re living in the transition phase from analog to digital; from broadcasting to social conversing.
How, then, can we find the proper education and training to become experts in these fields? Though there’s not one training program fit for everyone, there is one thing we can all do: learn how to learn.
