一、中枢神经系统递质十多年来,在中枢神经系统(CNS)中已发现很多种神经递质。其中属于儿茶酚胺类的递质有多巴胺、去甲肾上腺素及肾上腺素;属于吲哚胺类的递质有5-羟色胺及褪黑激素(melafonin)。乙酰胆硷过去被认为存在于外周神经系统,传递副交感神经冲动,现已证明它在中枢神经系统中也起着神经递质作用。组织胺和r-氨基丁酸(GABA)被认为是与神经内分泌功能有关的神经递质。此外,最近几 First, the CNS neurotransmitters For more than a decade, many neurotransmitters have been found in the central nervous system (CNS). Which belong to catecholamines are dopamine neurotransmitters, norepinephrine and epinephrine; belong to indole amines are serotonin and melatonin (melafonin). Acetylcholine, which was previously thought to be present in the peripheral nervous system and transmits parasympathetic impulses, has been shown to also act as a neurotransmitter in the central nervous system. Histamine and r-aminobutyric acid (GABA) are considered neurotransmitters associated with neuroendocrine function. In addition, the most recent
