我们在观察下脑干单胺类神经元对交感和付交感神经传出活动的影响时证明:交感和付交感神经的传出活动受到来自去甲肾上腺素能神经元和5-羟色胺能神经元的双重影响,并且其作用是相拮抗的。根据交感和付交感中枢同时接受双重的单胺类神经元投射的特点以及去甲肾上腺素能与5-羟色胺能神经元之间具交互支配的特点,推测下脑干单胺类神经元可能在交感-付交感交互抑 We observed the effect of monoamine neurons of the brainstem on sympathetic and sympathetic nerve efferent activity demonstrating that the efferent activity of sympathetic and sympathetic nerves is mediated by neurotransmitters from noradrenergic and serotonergic neurons The dual effect, and its role is antagonistic. According to the characteristics of both sympathetic and sympathetic centers accepting dual monoamine neuron projections and the reciprocal dominance of noradrenaline and serotonergic neurons, it is speculated that the brainstem monoamine neurons may be localized in Sympathetic - pay sympathetic interaction
