Russian Scientists Create Biomimetic Algorithm to Find Epileptogenic Areas of the Brain
Researchers from the HSE University Centre for Bioelectric Interfaces have designed a new method for detecting diagnostic markers of epilepsy, called interictal spikes, using EEG and MEG. Capable of accounting for various errors and artefacts, this method constitutes a valuable addition to the arsenal of means for automatic analysis of electrophysiological recordings in epilepsy patients, especially when the data are noisy. Precise localisation of epileptogenic cortical structures can enhance the effectiveness of neurosurgical interventions. The study was published in the Journal of Neural Engineering.
Card Index: City as a Palimpsest
Any cultural landscape is a narrative or a story. A big, modern city with its multiple contesting meanings and social practices, an ongoing dialogue of different eras, and physical spaces coexisting with imaginary ones can be compared to a complex, multi-layered text. A recent paper by Ivan Mitin, Associate Professor in the Faculty of Urban and Regional Development, portrays the big city as an enormous, continuously updated manuscript.
Researchers Explain How Massive Methane Emissions Affect Warming in the Arctic
Expeditions to the Eastern Arctic and Kara Seas investigated the thermal properties of bottom sediments. Numerous zones of bubbling methane flux were discovered in the shelf of the Laptev Sea and the East Siberian Sea, which researchers believe is affecting climate warming in the Arctic. The study has been published inMarine and Petroleum Geology.
Russian Researchers Assess the Power of T-Cell Immune Response to Omicron BA.1 and BA.2
Scholars from HSE University and the RAS Institute of Bioorganic Chemistry have demonstrated the efficiency of T-cell immune response against the Omicron variant of SARS-CoV-2. In approximately 90% of vaccinated Europeans, T-cell immunity was as effective against Omicron as with other variants. The results of the study were published in PeerJ.
Irresistible Passion: Philately in the USSR
Soviet-era postage stamps illustrate the country's history in miniature, from the early years following the Communist revolution to the 1980s' perestroika. Government and public attitudes towards philatelists reflected an overall distrust of any type of 'otherness'; indeed, why would anyone spend time studying and collecting postage stamps? Thus, it should come as no surprise that periods of philatelic internationalism were followed by times of isolationism and pressure on stamp collectors. Despite efforts to place philately within the procrustean bed of Soviet propaganda, people with a passion for stamps stood out from the crowd and were often perceived as dissenters. The discussion of Soviet philately presented below is based on a paper by philologist Konstantin Bogdanov, professor at the HSE Campus in St. Petersburg.
Russian Researchers Assessed the Likelihood of Sleep Disorders after COVID-19
A team of researchers from the HSE Centre for Cognition and Decision Making and the Central State Medical Academy conducted a study on sleep disorders, mood and fatigue after COVID-19. These factors are interrelated and the researchers recommend a comprehensive approach to treat the problem effectively. The work was published in the journal Neuroscience and Behavioral Psychology.
Foreign Languages Slow Down Brain Ageing
Medical advances are causing a gradual increase in average life expectancy. However, this comes at a price, as the number of cases of dementia and other neurodegenerative diseases grows with age. Researchers from HSE University (Russia) and Northumbria University (UK) have found that bilingualism can slow down and mitigate the course of age-related changes in the human brain. The study was published in Frontiers in Psychology.
Researchers Have Developed a Russian-Language Method for the Preoperative Mapping of Language Areas
Neurolinguists from HSE University, in collaboration with radiologists from the Pirogov National Medical and Surgical Centre, developed a Russian-language protocol for functional magnetic resonance imaging (fMRI) that makes it possible to map individual language areas before neurosurgical operations. The study was published in Frontiers in Human Neuroscience.
Researchers Investigate Differences Between Post-Stroke and Post-Surgery Aphasia
Researchers from the HSE Centre for Language and Brain worked with Russian doctors to address the differences between the symptoms of post-stroke aphasia and aphasia caused by glioma surgery. Post-surgery patients demonstrate moderately severe speech disorders that impact all aspects of language processing simultaneously. Understanding these differences will help doctors develop more effective therapies for speech disorders caused by surgical removal of gliomas. The results of the study were published in Brain and Language.
Tunnelling Contact Helps to Study Electron Structure of Carbon Nanotubes
Russian physicists have demonstrated how tunnelling contacts can be used for single-particle states spectroscopy in carbon nanotubes. The proposed technology of tunnelling contact fabrication and the spectroscopic method will help measure the exact nanotube bandgap value, which is the key characteristic required for design of any nanotubes-based electronic devices. Applied Physics Letters publishes the result of the study.
