Percent damage

Subject	Amygdala			Entorhinal cortex			Perirhinal cortex
Subject	L	R	Mean	L	R	Mean	L	R	Mean
A1	92	50	71	4	0	2	2	0	1
A2	54	93	74	0	1	0	0	0	0
A3	100	96	98	42	8	25	6	1	4
A4	93	97	95	3	5	4	0	0	0

Numerals indicate percent damage of left (L), right (R), and total (mean) volume for each of three structures: amygdala, entorhinal cortex, and perirhinal cortex. A1–A4 are monkeys with excitotoxic amygdala lesions.
