Effects of high frequency stimulation of dorsal and ventral regions of anterior area 25 of the limbic cortex on the tonic electrical activity of two postganglionic sympathetic nerves of stellate ganglion-inferior cardiac and vertebral nerves and arterial blood pressure were studied in anesthetized cats. It was revealed three types of medullary influences: generalized activation of both sympathetic nerves and pressor responses mainly in case of stimulation of ventral structures, generalized inhibition of electrical activity of both sympathetic nerves and depressor responses in case of stimulation of dorsal region of area 25 and selective modulation of activity, namely increase in activity of inferior cardiac nerve and simultaneous decrease of activity of vertebral nerve. According to data of our previous comparative studies of sympathetic responses of inferior and vertebral postganglionic nerves to stimulation of anterior and posterior hypothalamus as a working hypothesis it is supposed that the dorsal region of area 25 of limbic cortex is the analogy of trophotropic system of anterior hypothalamus, the ventral region--of ergotrophic system of posterior hypothalamus.
在麻醉猫身上，研究了高频刺激边缘皮质25区前侧背侧和腹侧区域对星状神经节的两条节后交感神经（下心神经和椎动脉神经）的紧张性电活动以及动脉血压的影响。结果发现了三种延髓影响类型：主要在刺激腹侧结构时，两条交感神经普遍激活且出现升压反应；在刺激25区背侧区域时，两条交感神经的电活动普遍抑制且出现降压反应；以及活动的选择性调节，即下心神经活动增加而椎动脉神经活动同时减少。根据我们之前对下心和椎动脉节后神经对下丘脑前侧和后侧刺激的交感反应的比较研究数据，作为一个工作假设，推测边缘皮质25区的背侧区域类似于下丘脑前侧的营养性系统，腹侧区域类似于下丘脑后侧的促营养性系统。
