An international team including researchers from the HSE Centre for Language and Brain and the HSE Institute for Cognitive Neuroscience have demonstrated the critical role of the left, but not the right, inferior frontal gyrus in action naming. The study findings are published in Brain Structure and Function.
In an innovative study, researchers from HSE University, RAN Institute of Linguistics, and the National Medical and Surgical Centre named after N.I. Pirogov measured and analysed high-frequency oscillations (HFO) in different regions of the brain. An automated detector predicted seizure outcomes based on HFO rates with an accuracy rate of 85%, and by applying machine learning, made it possible to distinguish between epileptogenic and non-epileptogenic HFO. The study’s findings are published in Frontiers in Human Neurosciences.
An international team of scientists from Russia, France and Germany (including researchers of the HSE Faculty of Computer Science, the HSE Artificial Intelligence Centre and the Artificial Intelligence Research Institute) have developed a new reinforcement learning algorithm (Bayes-UCBVI). This is the first Bayesian algorithm that has a mathematical proof of effectiveness and has been successfully tested in Atari games. The result was presented at the ICML-2022 conference.
HSE researchers have found genes characteristic of the most aggressive subtype of clear cell renal carcinoma. Having studied data on tumour samples from 456 patients, Grigory Puzanov, research fellow at the HSE Faculty of Computer Science International Laboratory of Bioinformatics, identified cancer subtypes associated with either a favourable or unfavourable course of the disease. The paper is published in Scientific Reports.
An international team of researchers from the HSE International Laboratory of Positive Psychology of Personality and Motivation, the Russian National Research Centre for Hematology, and a number of American universities examined the motivations of regular blood donors.
A team including HSE researchers has developed a way to use microfluidic chips to assess the toxic effects of drugs on humans. This device will help identify and minimise the side effects of drugs during the preclinical trial stage and reduce the need for animal experiments. The study is published in Bulletin of Experimental Biology and Medicine.
The image of a serial killer and/or rapist is a product of scientific discourse, transferred to the cinema, and then to TV series. In many films, the plot is based on finding and capturing such criminals by using a particular method — social and psychological profiling, and the appearance of a maniac in the cinema has been normalized today. Maria Marey, Senior Lecturer at HSE School of Philosophy and Cultural Studies, analysed how science and philosophy have contributed to the emergence of serial killer characters in popular culture, and how it affects the audience.
HSE Researchers Caused People to Behave Less Rationally by Suppressing Activity in Specific Parts of the Brain
Researchers at the HSE Institute for Cognitive Neuroscience have shown experimentally that magnetic stimulation of the prefrontal cortex of the brain causes test subjects to act less rationally, changing how they assess possible outcomes at the moment they make risky decisions. The scientists believe that the discovery will provide a better understanding of the mechanisms that give rise to gaming addiction. The results of the study were published in the journal Scientific Reports.
According to researchers of the Moscow City Pedagogical University (MSPU) and HSE University Vladimir Postavnev, Irina Postavneva, Vadim Peskov and Alexey Dvoinin, certain personality traits can help older scholars stay productive and creative for a long time. The study findings are published in Acta Biomedica Scientifica.
The informal economy is a global phenomenon found in both developed and developing countries. There remains no consensus among academics about how the informal sector impacts overall economic growth. Elena Kalmychkova and Alexander Lipanov of Lomonosov Moscow State University and HSE University examined the informal economic sectors of former Soviet republics and found that regardless of any potential negative impact, these informal economies eventually helped people adapt to a post-transition free market environment.
