Congratulations to Ossadtchi Alexey on the successful pre-defense of his doctoral dissertation!

On October 05, 2022 at the Department of Data Analysis and Artificial Intelligence, the preliminary defense of the doctoral dissertation "Methods for processing, decoding and interpretation of electrophysiological activity of the brain for problems of diagnosis, neurorehabilitation and therapy of neurocognitive disorders" by Alexey Ossadtchi was held.

Since the time of Galen, it has been suggested that it is the brain that makes us intelligent beings, provides our cognitive and analytical abilities, enables us to create and compactly accumulate knowledge about our world and our place in it. Whether it is true or not, and if it is true, to what extent, humanity still has to find out, and for this purpose we need both research tools and technologies for maintaining and restoring the brain function, capable of prolonging the period of active intellectual life of a person and thereby increasing the quantity and quality of knowledge passed from generation to generation.

Authors discussed the methods developed by the author for analyzing electrical activity of the brain aimed at increasing the completeness and accuracy of localization of neuronal sources and functional networks formed by them. 

Paradigms requiring real-time processing of brain activity signals form the basis of neurofeedback technology and neural interfaces, which are increasingly being used to explore and correct brain function or replenish lost bodily functions. Architectures of neural networks with interpretable decision rules and their application to motor and speech neural interfaces were discussed, as well as approaches to minimize the delay in neurofeedback that enhance the efficiency of this promising technology.
