概括
精神分裂症患者表现出脊侧前额叶皮层 (DLPFC) 到中脊丘脑 (MDl) 路径连接性的减少. 在人类研究中观察到的这一发现,翻译了非人类灵长类研究的见解,突出了精神分裂症中特定的神经变化.
科学领域:
- 神经科学是一个神经科学.
- 精神病学是一个精神病学.
- 神经成像是一种神经成像.
背景情况:
- 非人类灵长类动物 (NHPs) 的遗传神经调节揭示了特定神经回路的因果作用.
- 脊侧前额叶皮层 (DLPFC) 到侧侧间脊侧胸核 (MDl) 的通路与精神分裂症 (SCZ) 中常见的工作记忆缺陷有关.
研究的目的:
- 调查NHP中确定的DLPFC-MDl通路改变是否也存在于SCZ.人类患者中.
- 为了确定这种改变是否与其他精神疾病相比,是SCZ特有的.
主要方法:
- 利用了一个公开可用的,多站点,多疾病的磁共振成像 (MRI) 数据集.
- 在SCZ (N=91),大抑郁症 (MDD,N=133),自闭症谱系障碍 (ASD,N=120) 和健康对照 (HCs,N=511) 个体中评估了DLPFC-MDl通路的静止状态功能连接性.
主要成果:
- 与HC相比,SCZ组中发现DLPFC-MDl连接性明显减少.
- 在ASD或MDD组中没有观察到显著的低连接性,这表明疾病特异性变化.
- 低连接性是DLPFC-MDl通路的特征,不延伸到邻近的乳头核,表明焦点乳头异常.
结论:
- 这些发现支持从NHP研究到人类神经精神疾病的途径特定见解的翻译潜力.
- 这项研究确定了精神分裂症中特定于疾病的焦点体连接性改变.
- 结果强调DLPFC-MDl途径是理解和治疗精神分裂症相关认知缺陷的潜在目标.

Schizophrenia is a neurodevelopmental disorder whose origins are rooted in complex genetic components. Despite our burgeoning understanding, the pathophysiology of this disorder remains incompletely deciphered.
Researchers have identified genetic factors that increase susceptibility to schizophrenia, underscoring the intricate interplay between genetics and environment in disease development. At the core of schizophrenia's pathophysiology is excessive dopaminergic neurotransmission within...

Schizophrenia, a severe psychiatric disorder, arises from a complex interplay of biological factors, including genetic predisposition, structural brain abnormalities, neurotransmitter dysregulation, and developmental irregularities. These factors collectively contribute to the onset and progression of the disorder, which typically manifests in late adolescence or early adulthood.
