To assess the intensity of connections between different human brain areas we processed signals recorded from 16 intracranial electrodes in patients with focal epilepsy during wakefulness. We calculated spectral Coherence and Granger Causality at a network level. The comparison between the two procedures has confirmed the existence of privileged connections. The work analyzes and discusses the achieved results.

Abstract
To assess the intensity of connections between different human brain areas we processed signals recorded from 16 intracranial electrodes in patients with focal epilepsy during wakefulness. We calculated spectral Coherence and Granger Causality at a network level. The comparison between the two procedures has confirmed the existence of privileged connections. The work analyzes and discusses the achieved results.
