Whole-brain models generate directionality
whole-brain models allow for the examination of directional effects between brain regions by fitting functional connectivity (or nonreversibility) to the underlying structural connectivity derived by diffusion tensor imaging. Because DTI measures the directionality of water molecules, and allows us to reconstruct the connectome, fitting functional connectivity to it gives us a way of estimating what directional interactions might look like within functional brain dynamics.
