Abstract

The dynamical pattern of EEG transmission during an auditory working memory task was investigated by means of the Short-time Directed Transfer Function. The obtained temporal and spatial patterns of propagation were found to be in line with the neurophysiological hypotheses concerning the synchronization within and between the frontal and parietal brain structures. In particular the role of gamma and theta activity in information processing during a working memory task was elucidated. The modular organization of the brain networks was quantified by means of assortative mixing approach. The similarities and differences in the information transfer during visual and auditory working memory tasks were discussed.
