[引言] 伏隔核(nucleus accumbens)现被看作是脑内“腹侧纹体”的一部分,含有丰富的多巴胺介质,也是“中脑边缘多巴胺系统(the mesolimbic dopamine system)”中的一个主要环节。近来,对在此核内注入多巴胺或其协同药物能引起动物运动增多的现象已做了较广泛的研究。此外,目前已证明此核还同时受到五羟色胺能神经元的控制和调节,而且五羟色胺能神经元对多巴胺在伏隔核内所起的运动利助效应有抑制性影响。不仅如此,在实验中,设法损伤伏隔核或耗竭核内多巴胺的含量 [Introduction] The nucleus accumbens are now considered as part of the “ventral striatum” in the brain and are rich in dopamine mediators and are also a major component of “the mesolimbic dopamine system” Links. Recently, there has been a more extensive study on the phenomenon that dopamine or its synergistic drug can be injected into the nucleus to increase the movement of animals. In addition, it has been demonstrated that this nucleus is also controlled and regulated by serotonergic neurons at the same time, and serotonergic neurons have an inhibitory effect on dopamine’s motor-help effect in the nucleus accumbens. Not only that, in the experiment, trying to damage the nucleus accumbens or depletion of dopamine content
