Evolutionary game theory and network response to perturbation. Two distinct lesions to the default mode, dorsal attention and visual networks have been simulated using the EGN-B model. Nodes belonging to the DMN (node 5) and DAN (node 12) have been removed from the adjacency matrix and the resulting connectivity matrix has been estimated using EGN-B. A distinct pattern of rearrangement in connectivity is visible for the two simulations, with changes at both intra and inter-network level. The difference in connectivity strength between original and lesioned (i.e. residual) matrices highlights network-specific response to perturbation, with each lesion inducing differential amount of connectivity increase and decrease depending on the node being targeted (far right).
