Exposure to the color red increases functional connectivity throughout the Default Mode Network (DMN). The DMN is a wide network of far-flung neuronal nodes in the neocortex, wired together by white matter (axonal) cables. The main nodes of the DMN are centered in the medial prefrontal cortex (a part of the brain that is involved with decision making and memory consolidation), the posterior cingulate cortex, the parietal lobes (part of the brain that integrates various types of sensory information) and the hippocampus (the part of the brain that forms memories).
