Effect of unilateral lesion of amygdala on unmanifested response to Matatabi (Actinidia polygama) in cats.

The experiment was designed to elucidate the question whether the unilateral ablation of the amygdala significantly affects sexual behavior or not. For this purpose, the effect of the unilateral amygdalectomy upon Matatabi-response was investigated in the cat (R-cat), particularly in cats which showed unmanifested Matatabi-response in the innate status (NR-cat). Following the unilateral damage to the amygdala, NR-cats showed a significant manifestation in their Matatabi-response behavior, while R-cats indicated no change in it, their performance level being the same as preoperatively.
