Stimulation-Based Control of Dynamic Brain Networks

Building nonlinear brain networks.
(a) Subject-specific structural brain networks are built based on a parcellation of the brain into 83 anatomically defined brain regions (network nodes) with connections between regions given by the density of streamlines linking them. (b) The dynamics of each region are represented by a single Wilson-Cowan oscillator, and these oscillators are coupled according to the structural connectivity of a single subject. (c) Brain states are quantified by calculating the pairwise functional connectivity between brain regions.
