Effects of electrical stimulation of the lateral amygdaloid areas on ovulatory gonadotropin release were examined in adult Wistar female rats. Electrical stimulation was applied in rats in proestrus under ether anesthesia with square wave pulses of 0.5 ms duration and 100 Hz frequency for 30 min (30 sec on and off). Stimulation of the lateral amygdala blocked ovulation in 50% of animals when it was applied between 13:30 and 14:30 with a current of 300 muA. Stimulation of the medial amygdala under the same experimental condition was absolutely ineffective to block ovulation. Sham stimulation was also ineffective. In determining the gonadotropin concentration in serum, the stimulation into the lateral amygdala was observed to inhibit the ovulatory release of LH, FSH and prolactin. It may be said that the lateral amygdaloid area participates in the control of gonadotropin release in an inhibitory manner.
在成年Wistar雌性大鼠中，研究了电刺激杏仁核外侧区域对排卵性促性腺激素释放的影响。在乙醚麻醉下，对处于发情前期的大鼠施加电刺激，采用持续时间为0.5毫秒、频率为100赫兹的方波脉冲，刺激30分钟（开30秒、关30秒）。当在13:30至14:30之间以300微安的电流刺激杏仁核外侧时，50%的动物排卵受到抑制。在相同实验条件下，刺激杏仁核内侧对阻止排卵完全无效。假刺激也无效。在测定血清促性腺激素浓度时，观察到刺激杏仁核外侧会抑制促黄体生成素（LH）、促卵泡生成素（FSH）和催乳素的排卵释放。可以说，杏仁核外侧区域以抑制方式参与促性腺激素释放的控制。
