一、垂体后叶神经肽对学习和记忆过程的影响 De Wied和Bohus(1966)最先证明,垂体后叶提取物(Pitressin)能够使中枢神经系统过程发生持久的改变,即大鼠在注射Pitressin后表现出主动逃避反应的消退延缓。后来的实验又阐明了在粗提物中能够引起行为效应的活性物质是加压素(Vasopressin),它是下丘脑一垂体中的一个九肽。因此,注 First, the pituitary neuropeptide on learning and memory process De Wied and Bohus (1966) first demonstrated that the pituitary extract (Pitressin) can make a lasting change in the central nervous system process, that rats in the injection of Pitressin Postponed the regression of active avoidance response. Later experiments clarified that the active substance that can cause behavioral effects in crude extracts is Vasopressin, a nonapeptide in the hypothalamus-pituitary gland. So, note
