Corporal punishment reduces the white-matter wiring between prefrontal cortex and amygdala.

Evidence

The Teicher group’s DTI studies documented reduced fractional anisotropy in several white-matter tracts in adults with histories of childhood corporal punishment. Among the affected tracts: the arcuate fasciculus — a major association pathway connecting temporal and frontal language regions — and, critically, the uncinate fasciculus — the primary white-matter pathway connecting the prefrontal cortex to the amygdala. Reduced integrity of the uncinate fasciculus means reduced communication between the prefrontal cortex and the amygdala. Reduced top-down regulation. The brake — the prefrontal brake on amygdala reactivity that we described in Episode 96 — is not merely weaker at the level of cortical gray matter. The wiring that connects the brake to the alarm system is itself compromised. — , The Rod and the Child, 6242
