A new brain imaging study found links between authoritarian attitudes (both left- and right-wing) and structural differences in the brain, specifically reduced gray matter volume in the dorsomedial prefrontal cortex (right-wing) and reduced cortical thickness in the right anterior insula (left-wing).
Recent volumetric brain reconstructions reveal high anatomic complexity. Research shows brain anatomy satisfies universal scaling laws, implying criticality in the cellular brain structure. Findings enable comparisons of structural properties across different organisms.
