Abstract:
The article is devoted to EEG (electroencephalography) studying of connectivity of cortical areas involved in keeping vision information in the working memory. There was used VAR-modeling for describing signals got from connected with working memory brain zones. Brain connections were estimated the based on Granger Causality Partial Directed Coherence (PDC) and then compared by Wilcoxon signed-rank test. Connection intensity dependence on the executing task was found.
