“In this article we review Tononi's (2008) theory of consciousness as integrated information. We argue that previous formalizations of integrated information (e.g. Griffith, 2014) depend on information loss. Since lossy integration would necessitate continuous damage to existing memories, we propose it is more natural to frame consciousness as a lossless integrative process and provide a formalization of this idea using algorithmic information theory. We prove that complete lossless integration requires noncomputable functions. This result implies that if unitary consciousness exists, it cannot be modelled computationally.”

Unlike scanning techniques such as electroencephalography (EEG), which detects electrical activity at the skull's surface, fMRI produces measurements from deep inside the brain. It is also non-invasive, which makes it safer and more comfortable than positron emission tomography (PET), in which radioactive compounds are injected and traced as they flow around the body. fMRI has been applied to almost every aspect of brain science ever since. It has shown that the brain is highly compartmentalized, with specific regions responsible for tasks such as perceiving faces and weighing up moral responsibility; that the resting brain is in fact humming with activity; and that it may be possible to communicate with patients in a vegetative state by monitoring their brain activity. In 2010, neuroscientists used fMRI in more than 1,500 published articles.

Computational creativity is an emerging branch of artificial intelligence that places computers in the center of the creative process. Broadly, creativity involves a generative step to produce many ideas and a selective step to determine the ones that are the best. Many previous attempts at computational creativity, however, have not been able to achieve a valid selective step. This work shows how bringing data sources from the creative domain and from hedonic psychophysics together with big data analytics techniques can overcome this shortcoming to yield a system that can produce novel and high-quality creative artifacts. Our data-driven approach is demonstrated through a computational creativity system for culinary recipes and menus we developed and deployed, which can operate either autonomously or semi-autonomously with human interaction. We also comment on the volume, velocity, variety, and veracity of data in computational creativity.

"Scientists at CNRS, Aix-Marseille Université and AP-HM have identified a cerebral marker specific to autism that can be detected by MRI and is present as from the age of two years. The abnormality thus detected consists in a less deep fold in Broca’s area, a region of the brain specialized in language and communication, functions that are impaired in autistic patients. This discovery may assist in the earlier diagnosis and management of these patients. It has been made possible by the medical imaging processing skills of the Institut de Neurosciences de la Timone (CNRS/Aix-Marseille Université) and access to a homogeneous cohort of patients diagnosed at a very young age and all assessed using the same protocol at the Centre de Ressources Autisme PACA. The results of their collaboration are published on 12 January 2016 in Biological Psychiatry: Cognitive Neurosciences and Neuroimaging."
"The human brain does not come with an operating manual. However, a group of scientists from UC Santa Barbara and the University of Pennsylvania have developed a way to convert structural brain imaging techniques into “wiring diagrams” of connections between brain regions.
"Three researchers from UCSB’s Department of Psychological & Brain Sciences — Michael Miller, Scott Grafton and Matt Cieslak — used the structure of neural networks to reveal the fundamental rules that govern which parts of the brain are most able to exert cognitive control over thoughts and actions. This study is the first to provide a mechanistic explanation for how the frontal cortex exerts control over the trillions of individual neurons that allow people to stay focused on one task or switch to a radically different one. The findings appear today in the journal Nature Communications."

“ Before you begin designing Gamification for eLearning it is important to keep a keen focus on your learners rather than the games. Understanding your audience and the types of games that will motivate them is the key to success with Gamification theory. One way to understand which gaming components would motivate learners is through surveying. Another method used is trial and error supported by learning analytics from your LMS. If designed well, Gamification will effectively support learning objectives and provide learners with immediate feedback on their progress and actionable goals to move forward. Let’s take a closer look at the gaming components that will help you to achieve this. As you read through them, think of ways that they can be used together.”
