觉醒状态下脑内组胺神经元活动加强已有的证据表明，组胺（ＨＡ）起着神经递质和／或神经调质的作用，且可能和多种脑机能的调节有关。在哺乳动物脑内，ＨＡ是在组胺酸脱羧酶作用下由左旋（Ｌ）组胺酸脱羧而成的。组胺Ｎ位甲基转移酶可使组胺失去活性。ＨＡ的中枢作用受突...
Histamine Neurons Enhance Activity in the Brain During Arousal There is evidence that histamine (HA) acts as a neurotransmitter and / or neuromodulator and may be involved in the regulation of various brain functions. In mammalian brains, HA is formed by the decarboxylation of L-histidine under the action of histidine decarboxylase. Histamine N-methyltransferase can histamine loss of activity. HA central role by sudden ...
