METHOD OF CONSTRUCTING A DATA STRUCTURE REPRESENTATIVE OF A DYNAMIC REORGANIZATION OF A PLURALITY OF BRAIN NETWORKS, CORRESPONDING DEVICE AND PROGRAMME

摘要

A method for determining a sequence of activation of a set of brain networks by an electronic device in the course of a predetermined cognitive task. The method includes: obtaining at least one time series of data on encephalographic activities, according to a predetermined sampling value, the data on activities representing a signal captured on the cranial surface by a capture device, during the execution of the predetermined cognitive task by at least one individual, delivering a set having at least one measurements vector per sample of the time series; for each measurements vector, determining connectivity between cortical sources, the cortical sources being obtained through measurements of a measurements vector, delivering a connectivity network; and grouping connectivity networks according to a resemblance parameter delivering a set of groups of grouped connectivity networks, each representing an activity of a given brain network at a given instant.
