Brain connectivity refers to the description of how brain areas interact, encompassing different and interrelated aspects such as anatomical links (structural connectivity), statistical dependencies (functional connectivity), or causal interactions (effective connectivity) . As such, the study of brain connectivity has become central both for the investigation of neurophysiological processes typically engaged in cognitive and perceptive processing and for the assessment of a wide variety of neurological disorders. Behaviors and actions, from simple to most complex, entail interaction and interdependence with the environment and the contribution of large- scale cortical areas depending on the orchestrated activation of large neuronal ensembles. Understanding how neuronal networks process environmental stimuli, how information is encoded as a function of the network structure and how different brain networks communicate to each other during a specific cognitive function is an essential step to interact with the nervous system.
