A positive correlation has been discovered between the neural activity in the nucleus accumbens of study participants as they were presented with photographs of dishes from the menu of the Chaihona No. 1 restaurant chain and the sales performance of said dishes in the chain's establishments. This finding was made by a team of researchers of the HSE Institute for Cognitive Neuroscience, Lomonosov Moscow State University, and ETH Zurich (Switzerland). The study findings have been published in PLoS One.

People who are fluent in two or more languages are less susceptible to age-related mental disorders. They more quickly process information and make decisions, have better memories, and can even better identify emotions. Scientists from various countries discussed the influence of a second language on the processes of cognitive aging at the international symposium ‘Bilingualism: Proper Learning, Effective Communication, and Pleasant Old Age’ hosted by HSE University.

After studying the brain scans of 13 Russian cosmonauts who participated in space missions to the ISS from 2014 to 2020, scientists discovered that prolonged exposure to microgravity had an impact on the connectivity of the brain structures responsible for adapting to unfamiliar conditions. The study revealed that these connections may not always return to their original state after the flight. The paper has been published in Communications Biology.

Researchers at the HSE Institute of Cognitive Neuroscience have discovered that analysing the electrical activity in the brains of a small group of people and studying their visual attention makes it possible to predict the impact of an online advertising campaign on a much larger group of 300,000 consumers. The paper has been published in Brain Sciences.

HSE researchers have developed an algorithm for estimating individual response preparation period duration. Their approach can help diagnose disruptions in decision-making and motor functions associated with certain diseases. The study findings are published in PLoS ONE. The research was financed by a megagrant from the Russian government as part of the 'Science and Universities' National Project.

Researchers from HSE University and the Moscow State University of Medicine and Dentistry have developed a machine learning model that can predict the word about to be uttered by a subject based on their neural activity recorded with a small set of minimally invasive electrodes. The paper 'Speech decoding from a small set of spatially segregated minimally invasive intracranial EEG electrodes with a compact and interpretable neural network' has been published in the Journal of Neural Engineering. The research was financed by a grant from the Russian Government as part of the 'Science and Universities' National Project.

A study by the HSE Centre for Language and Brain has confirmed the role of the corpus callosum in language lateralisation, ie the distribution of language processing functions between the brain's hemispheres. The authors came up with an innovative language task for their study subjects and applied advanced neuroimaging methods to the data collected. A paper on their findings has been published in PLoS ONE.  The research was financed by a grant from the Russian government as part of the 'Science and Universities' National Project.

An international team of researchers including Sofya Kulikova, Senior Research Fellow at the HSE University-Perm, found that ketamine, being an NMDA receptor inhibitor, increases the brain's background noise, causing higher entropy of incoming sensory signals and disrupting their transmission between the thalamus and the cortex. This finding may contribute to a better understanding of the causes of psychosis in schizophrenia. An article with the study’s findings has been published in the European Journal of Neuroscience.
