Data presented are the percentage of normal volume damaged within the amygdala as a whole, the lateral, basal, accessory basal and central nuclei, as well as the adjacent rostral hippocampus (from anterior tip to posterior extent of the uncus) and entorhinal cortex. L – percentage of damage to the left hemisphere; R – percentage of damage to the right hemisphere; Avg – average of L and R.
