Scientists at HSE University have learned that disagreeing with the opinion of other people leaves a ‘trace’ in brain activity, which allows the brain to later adjust its opinion in favour of the majority-held point of view. The article was published in Scientific Reports.
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.
Oksana Zinchenko , Research Fellow at the Institute of Cognitive Neuroscience, HSE University, has conducted meta-analysis of 17 articles to find out which areas of the brain are involved in decision-making for rendering social punishment. It would appear that in case of both victims of violations as well as witnesses, punishment decisions activate the brain regions responsible for focusing one’s attention, processing information, and responding effectively to social interaction. The findings of the study were published in Scientific Reports.
When bidding in a competitive market, our brains use a special type of heuristic to adjust the price depending on the success of previous attempts to buy goods. Moreover, this learning mechanism involves not only the cerebral cortex, but the evolutionary ancient brain area of the striatum. This was the conclusion reached by neuroscientists from the HSE Institute of Cognitive Neuroscience and the Research Center of Neurology (Moscow, Russia) in a study that was published in the European Journal of Neuroscience.
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.
An international team of Russian and Belgian researchers has found out that space travel has a significant impact on the brain: they discovered that cosmonauts demonstrate changes in brain connectivity related to perception and movement. Some areas, such as regions in the insular and parietal cortices, work more synchronously with other brain areas after the space flight. On the other hand, connectivity of some other regions, such as the cerebellum and vestibular nuclei, decreases. The results of the study were published in Frontiers in Physiology.
