神经系统存在着大量游离氨基酸,它参与神经细胞的代谢过程,并维持细胞膜内外水分和离子的平衡,因此神经细胞的功能活动,与氨基酸息息相关,此外突触的神经递质有兴奋性和抑制性两类,这种递质都是氨基酸,前者有谷氨酸和门冬氨酸等,后者有r-氨基丁酸等,晚近Perry等发现精神分裂症大脑的视丘和伏核(nucleus There are a large number of free amino acids in the nervous system, which is involved in the metabolic processes of nerve cells and maintain the balance of water and ions inside and outside the cell membrane, so the functional activity of nerve cells, and amino acids are closely related, in addition to the synaptic neurotransmitter excitability and inhibition Two types of neurotransmitters are amino acids, the former with glutamic acid and aspartic acid, the latter with r-aminobutyric acid and so on, recently found Perry and other schizophrenia brain hypothalamus and nucleus (nucleus
