Network Perspective on Brain Function

Network Perspective on Brain Function

(p.193) 8 Network Perspective on Brain Function
The Cognitive-Emotional Brain

Luiz Pessoa

The MIT Press

This chapter describes a general framework for understanding brain function, one that addresses the relationship between brain and behavior. To do so, it first characterizes the mapping between structure and function. The chapter argues that a network perspective should supplant the common strategy of understanding the brain in terms of individual regions. Yet, although this perspective is needed for a fuller characterization of the mind-brain, it should not be viewed as a panacea. For one thing, it does not dissolve the challenges posed by the many-to-many mapping between regions and functions – however useful the network approach may be, we should not anticipate a one-to-one mapping when it is adopted. The chapter also describes how the function of brain regions can be characterized in a multidimensional manner using diversity profiles, which can also be used to describe the way different brain regions participate in networks.

Keywords:   structure-function, networks, modularity, functional connectivity, anatomy, community detection, functional fingerprints
