A, B, Ejaculation frequency and total intromission frequency for animals with amygdala lesions or sham lesions in experiment 1. There were no significant differences in ejaculation frequency or total intromission frequency for animals with sham lesions. Animals with amygdala lesions displayed significantly fewer ejaculations and fewer total intromissions after surgery (POST) compared with before surgery (PRE). Microinjections of apomorphine (APO), but not vehicle (VEH), restored measures of copulation for animals with amygdala lesions. Values are expressed as mean ± SEM (*p < 0.05).
