Abstract

The Short-time Directed Transfer Function was used for estimation of dynamical patterns of brain activity propagation. The SDTF is based on the multivariate autoregressive model, where all channels of the process are considered simultaneously. Time-frequency patterns of EEG propagation were found for the task of finger movement and its imagination and for the Continuous Attention Test. The results supported the neurophysiological hypotheses concerning information processing in brain and in particular the theory of active inhibition.
