精神分裂症的阳性、阴性和认知症状是什么引起的?没有一个单一的基因对这种疾病有很大的贡献,这一发现强调了电路的重要性。因此,许多蛋白质可能导致的某些电路异常是可能的原因。关于所涉及的电路有几个主要假设:1)PFC中兴奋/抑制平衡的改变; 2)γ范围内的异常EEG振荡; 3)与丘脑(特别是中线核)变化相关的θ/δ EEG功率增加; 4)海马活动过度和随之而来的多巴胺功能亢进;或5)必然放电缺陷。这些假设的证据将被审查。
What causes the positive, negative, and cognitive symptoms of schizophrenia? The importance of circuits is underscored by the finding that no single gene contributes strongly to the disease. Thus, some circuit abnormality to which many proteins can contribute is the likely cause. There are several major hypotheses regarding the circuitry involved: 1) a change in the balance of excitation/inhibition in the PFC; 2) abnormal EEG oscillations in the gamma range; 3) an increase in theta/delta EEG power related to changes in the thalamus (particularly midline nuclei); 4) hyperactivity in the hippocampus and consequent dopamine hyperfunction; or 5) deficits in corollary discharge. Evidence for these hypotheses will be reviewed.
