Abstract

Direct application of serotonergic of beta-adrenergic receptor blockers to anterior or posterior areas of the hypothalamus induced lordosis in intact estrogen-primed male rats. Such treatment with an alpha-adrenergic blocker or systemic administration of progesterone failed to increase lordosis. Centrally elicited lordosis did not occur without estrogen priming. Anatomical and neurochemical similarity may exist in the brain mechanism mediating lordotic behavior in male and female adult rats.

摘要

将血清素能或β-肾上腺素能受体阻滞剂直接应用于完整的经雌激素预处理的雄性大鼠下丘脑的前部或后部会诱发脊柱前凸。用α-肾上腺素能阻滞剂进行这种治疗或全身给予孕酮均未能增加脊柱前凸。未经雌激素预处理不会出现中枢引发的脊柱前凸。在成年雄性和雌性大鼠中介导脊柱前凸行为的脑机制可能存在解剖学和神经化学上的相似性。
