Viral Brain Networks

A growing body of research has identified the presence of multiple brain networks supporting human behavior. These networks include a salience network involving dorsal anterior cingulate and anterior insula regions thought to be relevant to attending to survival-relevant events in the environment; a central executive network (CEN) consisting of regions in the middle and inferior prefrontal and parietal cortices engaged by many higher level cognitive tasks and thought to be involved in adaptive cognitive control; and a default mode network (DMN) consisting of regions in medial frontal cortex and posterior cingulate, among others, that reliably reduce their activity during active cognitive demands and which may be involved in attention to internal emotional states or self-referential processing[1]. ___ http://ccpweb.wustl.edu/pdfs/2013barch-cell.pdf

The network approach to brain function and human cognition is opening a new window into the conceptualisation of “human intelligence.” The model of 3 interacting brain networks — the Default Mode…
