The supraoptic neurons were differentiated into different types by means of antidromic stimulation of the hypothalamo-hypophyseal tract and their responses to i. v. administration of 1 M NaCl solution. I. v. administration of hypertonic NaCl solution induced the activation response in all the neurons. The neurons responding with a single spike to the tract stimulation, reacted only to administration of 1 M NaCl. The neurons responding orthodromically with a high-frequency burst as well as the neurons with no responses to the tract stimulation, revealed reactions of activation similar in time characteristics in administration of both the physiological and the hypertonic solutions. Besides, these neurons were responsive to stimulation of the ipsilateral femoral nerve as well. Possible role of these types of neurons in the functional organization of the rat hypothalamus' supraoptic nucleus, is discussed.
通过对下丘脑 - 垂体束的逆向刺激及其对静脉注射1 M NaCl溶液的反应，视上核神经元被区分为不同类型。静脉注射高渗NaCl溶液可诱导所有神经元产生激活反应。对束刺激仅产生单个动作电位反应的神经元，仅对1 M NaCl的注射有反应。对束刺激产生高频爆发性顺向反应的神经元以及对束刺激无反应的神经元，在注射生理溶液和高渗溶液时均表现出时间特征相似的激活反应。此外，这些神经元对同侧股神经的刺激也有反应。文中讨论了这些类型的神经元在大鼠下丘脑视上核功能组织中的可能作用。
