Intended ibotenic acid damage to the amygdala (Neo-Aibo) and unintended damage to adjacent areas, as measured on postmortem, histological slices. LT%, percent damage in the left hemisphere; RT%, percent damage in the right hemisphere; X%, average damage to both hemispheres; W% weighted average damage to both hemispheres (W% = (LT% X RT%)/100).
