Abstract:
A substantial body of evidence implicates dysfunction in N-methyl-d-aspartate receptors (NMDARs) in the pathophysiology of schizophrenia. This article illustrates how NMDAR dysfunction may give rise to many of the neurobiological phenomena frequently associated with schizophrenia with a particular focus on how NMDAR dysfunction affects the thalamic reticular nucleus (nRT) and pedunculopontine tegmental nucleus (PPTg). Furthermore, this article presents a model for schizophrenia illustrating how dysfunction in the nRT may interrupt prefrontal regulation of midbrain dopaminergic neurons, and how dysfunction in the PPTg may drive increased, irregular burst firing.
摘要:
大量证据表明精神分裂症的病理生理学中N-甲基-d-天冬氨酸受体(NMDARs)的功能障碍。本文说明了NMDAR功能障碍如何引起许多与精神分裂症经常相关的神经生物学现象,特别关注NMDAR功能障碍如何影响丘脑网状核(nRT)和足脑桥被盖核(PPTg)。此外,本文提出了一个精神分裂症模型,说明nRT中的功能障碍如何中断中脑多巴胺能神经元的前额叶调节,以及PPTg中的功能障碍如何驱动增加,不规则的爆发射击。
