摘　　要：鸣禽脑部的一些鸣唱核团与听觉核团接受来自中脑儿茶酚胺(catecholamine,CA)能神经元发出的纤维投射,并且存在多种儿茶酚胺类受体的表达。研究发现在不同的鸣唱环境下,中脑儿茶酚胺能神经元活性及其支配靶区即早基因的表达水平均存在显著差异。表明中脑儿茶酚胺能神经元在调节鸣唱行为和听觉信息处理等方面发挥重要作用。介绍了近年来有关儿茶酚胺能神经元活动与鸣唱行为和听觉信息处理的研究进展。Song and auditory nuclei are innervated by midbrain catecholaminergic fibers, and express dopamine and norepinephrine receptors. In different social environment, activity and immediate early genes expression of midbrain catecholaminergic cells and controlling target regions are significantly different. These studies suggest that the midbrain cateeholaminergie neurons involve in regulating birdsong and auditory process. The involvement of cateeholaminergic neurons in song behavior and auditory process is reviewed.
