HSE Researchers to Create a Mathematical Model of the Brain
The HSE Centre for Cognition and Decision Making together with a group of other Russian research centres is about to begin work on creating a mathematical model of the human brain. With its help scientists will be able to study the processes which take place in the brain and brain disease. It could be used for medical purposes in the future.
In October this year the HSE Centre for Cognition and Decision Making (CCDM) with the Lobachevsky University, RAS Institute of Laser and Information Technologies and other Russian research centres won a federal competition to work on applied research in neurotechnology.
‘The human brain is a kind of bio-computer but we know very little about most of its processes,’ explains Boris Gutkin, Head of the working group on Neuromodeling at CCDM HSE. ‘Our aim is to understand the principles of information processing and changes in the brain. We will make a model of how signals are processed in brain cells, or neurons. Once we have studied the processes on an experimental level we plan to create a general mathematical model of the brain with our colleagues. We’ll use it to study different brain diseases and in particular Alzheimer’s, epilepsy and propose ways to treat them.’
Three years have been timetabled for the theoretical part of the project. After that, pre-clinical trials will begin. It is hoped that in the future the model will be used in medicine.
Movement Recovery after Stroke Depends on the Integrity of Connections between the Cerebral Cortex and the Spinal Cord
A team of scientists, with the first author from the HSE University, were investigating which factors are the most important for the upper limb motor recovery after a stroke. The study is published in Stroke, the world's leading journal for cerebrovascular pathology.
Researchers at the HSE Institute for Cognitive Neuroscience have shown experimentally that economic activity can actively change the brain. Signals that predict regular financial losses evoke plastic changes in the cortex. Therefore, these signals are processed by the brain more meticulously, which helps to identify such situations more accurately. The article was published in Scientific Reports.
HSE University scientists have for the first time in the world investigated the impact of delayed reinforcement signals in neurofeedback (NFB) training. They have experimentally proven that reducing the delay in feedback (decreasing feedback latency) can significantly increase the efficacy of training.
Researchers at the HSE University Centre for Language and Brain, in cooperation with a professor of neuropsychology from Lomonosov Moscow State University and specialists from the Centre for Speech Pathology and Neuro-rehabilitation, evaluated the diagnostic validity of the Standardized Assessment of Reading Skills in Russian (SARS) and checked whether the available normative data are current. The results of the study, the updated levels for reading speed, as well as the control levels for evaluating these indicators, were published in The Russian Journal of Cognitive Science.
Russian Research Team Gains Deeper Insight into the Workings of the Human Brain during Group Problem Solving
A team of Russian researchers with the participation of a leading researcher at HSE University, Ekaterina Pechenkova, found that during group problem solving the components of the social brain are co-activated, but they do not increase their coupling during cooperation as would be suggested for a holistic network. The study was published in Frontiers in Human Neuroscience.
Many people are able to recognize the personality traits of the person they are talking to by their facial features. Experts in non-verbal communication can do this even with a photograph. But is it possible to teach artificial intelligence to do the same?
An international team of researchers carried out an experiment at HSE University demonstrating that knowledge of several languages can improve the performance of the human brain. In their study, they registered a correlation between participants’ cognitive control and their proficiency in a second language.
A ‘Mega-Grant’ Competition for ground-breaking research projects funded by the Russian Ministry of Science and Higher Education was held for the seventh time, and this year’s competition winners included two projects that will be based at HSE University campuses. One research group will study dynamic systems at HSE – Nizhny Novgorod, and a new social neurobiology laboratory will begin work at HSE University in Moscow.
On September 23-24, the CCCP19 Symposium ‘Cognition, Computation, Neuroeconomics and Performance’ will be held at HSE University. The goal of the symposium is to exhibit cutting edge research at the CCDM, a leading cognitive neuroscience research centre in Russia, and LNC2, a leading European research centre in neuroeconomics, cognitive neuroscience and neural theory. Ahead of CCCP19, the HSE News Service spoke with the conference organizer and several invited speakers about the plan for this symposium and the importance of their research in the field.
While Roscosmos is discussing future manned flights to Mars, NASA plans to open the International Space Station for commercial tourism, and SpaceX is testing its Starship Mars prototype, scientists are seriously concerned about the impact of prolonged stay in space on the human body. While the effects of weightlessness on bones, muscles and the vestibular system are well known, how the human brain copes with microgravity has yet to be fully examined. IQ.HSE has compiled the latest research on this topic.
