Abstract

The innervation of forebrain catecholamine (CA) were experimentally investigated with use of sensitive fluorescence method of glyoxylic acid formaldehyde in the brain of the bull frog, Rana catesbiana. The CA of the olfactory bulb is supplied by CA neurons situated in olfactory bulb. And CA neurons in the hypothalamus contribute the main source for the forebrain CA except olfactory bulb. The hypothalamic CA neurons also give rise to long descending axons to innervate the brain stem. Judging from their anatomical aspects it seems that the structure homologous to mammalian nigro-neostriatal dopamine or mesolimbic dopamine system is not present in amphibian brain.

摘要

采用灵敏的乙醛酸 - 甲醛荧光法,对牛蛙(Rana catesbiana)脑内前脑儿茶酚胺(CA)的神经支配进行了实验研究。嗅球的CA由位于嗅球内的CA神经元提供。下丘脑的CA神经元是除嗅球外前脑CA的主要来源。下丘脑的CA神经元还发出长的下行轴突支配脑干。从解剖学角度判断,两栖动物脑内似乎不存在与哺乳动物黑质 - 新纹状体多巴胺系统或中脑边缘多巴胺系统同源的结构。
