a The 202-node network of the model. Each node represented either a cortical or sub-cortical region. Each node had two units, one unit with spiking activity and one unit with oscillatory activity. The oscillatory layer influenced the spiking layer within each node through phase-amplitude coupling. The connectivity within each layer was estimated with diffusion weighted imaging. b Synchronization was created by increasing the activity from the thalamus to regions in the cortical network to be synchronized, which was either the posterior theta (blue) or dorsal alpha (red) network. c Model synchronization in the posterior network after increased thalamic input to the network. Synchronization was calculated using phase-locking-values. d Model synchronization in the dorsal network.
