多巴胺对鸣禽发声相关神经元活动的调控
THE CONTROL OF DOPAMINE TO VOCAL RELATED NEURONS IN SONGBIRDS

摘要: 鸣禽多巴胺(DA)神经元主要分布于中脑腹侧被盖区-黑质体致密部(VTA-SNc复合体)和中脑导水管周围灰质(PAG),并分别发出纤维投射至鸣唱控制核团前脑纹状X区、弓状皮质栎核(RA)和高级发声中枢(HVC).近年研究表明,中脑向鸣唱控制核团中释放的DA可以调控鸣唱控制核团中神经元的活动,进而调节鸣禽的鸣唱行为.该文对近年来,多巴胺对鸣禽发声相关神经元活动的调控研究做一综述.Abstract: DA neurons distributed throughout VTA-SNc and PAG of midbrain in songbirds, and projected to X area, RA and HVC. In recent years, research showed that DA controls the activity of neurons in song system, and controls the song behavior.This paper reviewed progress in this field.
