Abstract :
Short-time directed transfer function, defined in the framework of multivariate autoregressive model, makes possible determination of the directions of propagation of EEG activity as a function of time and frequency. The EEG propagation in beta and gamma bands was estimated for the same subjects in imagined and real hand movement task. The concise patterns of propagations bearing some similarities in both tasks, but differing mainly in respect of time course of communication between structures, was found
