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. It is concluded from the present results that even the unilateral ablation of the amygdala affects sexual behavior significantly, this being in contrast to many previous reprots. The present finding implies that individual differences in sexual behavior appear to depend on the neural basis of the amygdala, supporting an assumption that the amygdala is a controlling center of sexual and emotional behaviors.
该实验旨在阐明单侧杏仁核切除是否会显著影响性行为这一问题。为此，研究了单侧杏仁核切除术对猫（反应性猫，R-cat），尤其是对那些在先天状态下未表现出猫薄荷反应的猫（无反应性猫，NR-cat）的猫薄荷反应的影响。单侧杏仁核损伤后，NR-cat在猫薄荷反应行为上表现出显著变化，而R-cat则无变化，其表现水平与术前相同。从目前的结果可以得出结论，即使是单侧杏仁核切除也会显著影响性行为，这与之前的许多报道相反。目前的发现表明，性行为的个体差异似乎取决于杏仁核的神经基础，支持了杏仁核是性和情感行为控制中心的假设。
