Scores are the mean percentage of correct responses over blocks of five sequential delays up to the delay shown in the heading of the table (i.e., 5 min, delays ranging from 0.5 to 4.5 min; 10 min, delays ranging from 5.5 to 9.5 min, etc.). NC1–NC4, Unoperated control monkeys; AH4–AH7, monkeys with bilateral excitotoxic lesions of the amygdala and hippocampus.
