Sources of brain activity relevant and not relevant for classifying of EEG patterns, corresponding to motor imagination
Result description
The paper examines the sources of brain activity, contributing to EEG patterns, corresponding to motor imagination. The accuracy of their classifying specifies the efficiency of brain-computer interface (BCI), allowing to control external technical devices directly by signals of brain activity instead of natural muscle forces. The sources of brain activity corresponding to motor imagination are revealed by Independent Component Analysis (ICA). EEG during motor imagination is shown to be a superpositionof components dependent and not dependent of the type of imaginary movement. Components dependent on the type of imaginary movement are relevant for EEG pattern classifying. They are localized in central brain areas. Components not dependent of the typeof imaginary movement are localized in occipital areas. They relate to the attention to task performance independently of the imaginary movement and not relevant for BCI efficiency. Excluding of these components from EEG patterns improves

Istočniki aktivnosti mozga, značimyje i neznačimyje dlja klassifikacii patternov EEG, sootvetstvujuščich voobraženiju dviženij
Original language description
Pokazano, čto pri voobraženii dviženij aktivnosť mozga javljajetsja superpozicijej komponent kak zavisjaščich, tak i ne zavisjaščich ot tipa voobražajemogo dviženija. Pokazano, čto isključenije poslednich iz analiza značitelno povyšajet effektivnosť interfejsa mozg-kompjuter, osnovannogo na raspoznavanii tipov voobražajemych dviženij.
