下丘脑在整个边缘系统中虽然只占一小部分,但却在许多行为和内脏活动的调节功能中发挥特别重要的作用.一方面,边缘皮层、杏仁、隔区、海马等高级中枢通过下丘脑影响低位脑干及垂体,对摄食、饮水、性行为、攻击和防御等行为,以及各种内脏的交感、副交感性活动、内分泌腺的分泌等进行调节.另一方面,下丘脑本身还发出纤维影响高级中枢,并受来自低位中枢的投射纤维影响,实现其调节功能.前人的大量工作 Although only a small part of the entire limbic system, the hypothalamus plays a particularly important role in many behavioral and visceral regulation functions: on the one hand, the superior cortex of the marginal cortex, almonds, septum and hippocampus passes through the hypothalamus Affect the lower brain stem and pituitary gland, regulation of feeding, drinking, sexual behavior, attack and defense, and sympathetic, parasympathetic activity of various internal organs, secretion of endocrine glands, etc. On the other hand, the hypothalamus itself also sends fiber Affect the high center, and by the low center of the projection fiber effects, to achieve its regulatory function. A large number of previous work
