Abstract
The injection of epinephrine into the third ventricle of the rat brain causes a biphasic elevation and depression in the integrated multiple-unit electrical activity of the median eminence. Activity in the arcuate nucleus decreases after the injection of the catecholamines. These changes in the integrated multiple-unit electrical activity may be related to the secretion of hormones by the anterior pituitary gland.
摘要
将肾上腺素注射到大鼠脑的第三脑室会导致正中隆起的综合多单位电活动出现双相升高和降低。注射儿茶酚胺后，弓状核的活动会减少。综合多单位电活动的这些变化可能与垂体前叶激素的分泌有关。
