How does social and sexual information processing map onto cortical circuits?
Addressing this question has been difficult, because of a lack of
circuit-oriented social neuroscience and an absence of measurements from
interacting brains. Recent work showed social information is already
differentially processed in the primary sensory cortices. Converging evidence
suggests that prefrontal areas contribute to social interaction processing and
determining social hierarchies. In social interactions, we identify gender in
split seconds, but after centuries of anatomy we are still unable to distinguish
male and female cortices. Novel data reinforce the idea of a bisexual layout of
cortical anatomy. Physiological analysis, however, provided evidence for sex
differences in cortical processing. Unlike other cortical circuits, sexual
processing circuits undergo major rewiring and expansion during puberty and show
lasting damage from childhood abuse.
