Figure I Measuring integration and differentiation in neural dynamics, for a system composed of N elements. (a)CN is calculated as the sum of the average MI over N/2 sets of bipartitions indexed by k (e.g. for k=1 an average MI is calculated over N bipartitions). (b) Φ is calculated as the EI across the MIB. To calculate EI for a given bipartition (indexed by j), one subset is injected with maximally entropic activity (orange stars) and MI across the partition is measured. (c)cd is calculated as the fraction of interactions that are causally significant according to Granger causality. A weighted (and unbounded) version of cd can be calculated as the summed magnitudes of all significant causal interactions (depicted by arrow width).
