Extended Data Fig. 8: Alternative measure of hierarchy.
From: Revisiting the global workspace orchestrating the hierarchical organization of the human brain
Inspired by the neuroanatomical research by Markov and colleagues, we computed a similar measure of hierarchy as the fraction of feedforward and feedback (FF) organisation. We computed this for the seven tasks and for resting state (top row). As can be seen from the correlation matrices, this FF Hierarchy measure is similar to Gout for all seven tasks (mean correlation is 0.81 and the mean p-values are p < 0.001). On the other hand FF Hierarchy is only non-significantly correlated with Gin, the integrative measure of incoming information flow (mean correlation is −0.02 and the mean p-value is p = 0.243).
