Dynamic connectivity and dynamic affiliation Comment on 'Understanding brain networks and brain organization' by L. Pessoa

摘要

Structure-function mapping in the human brain is a non-trivial endeavor that has occupied neuroscientists for many years. While a network approach, elegantly summarized by Pessoa [1], has for the most part supplanted simple one-to-one mapping schemes, several outstanding issues remain. The concept of "dynamic affiliation" of a particular brain region with a network in a certain context goes a long way towards providing a more sophisticated description of how any given region may participate in multiple cognitive processes. Despite the considerable insights into brain function provided by the network perspectives summarized by Pessoa, it is apparent that "rigorous characterization of brain networks is in its infancy".
