Group differences in node degree. The total number of functional connections from a region to all other regions, are plotted on the mouse brain. Warm colors are regions with higher node degree in DA exposed males and cool colors are areas with higher node degree in saline exposed males. DA exposed animals have global connectivity, that is, more connections (higher degree) to the piriform cortex (pir), secondary motor area (mo), visual (vis), and dorsal anterior cingulate (aca). DA exposed animals have lower degree to the infralimbic cortex (inf), taenia tecta (tt), nucleus accumbens (acb), anterior olfactory (aob), and ventral lateral orbital area (orb). All z-scores visualized are p < .05 based on 10,000 random permutations.
