精神分裂症患者在丘脑亚区域,特别是小脑和皮质的动态功能连接 (dFC) 发生变化. 这种thalamic失联在精神分裂症病理生理学中至关重要.
科学领域:
- 神经成像是一种神经成像.
- 精神病学是一个精神病学.
- 功能连接的功能连接性
背景情况:
- 之前的研究表明精神分裂症的乳头和乳头皮质电路受损.
- 精神分裂症中泰拉马斯的动态功能连接 (dFC) 模式尚不清楚.
研究的目的:
- 在精神分裂症患者中探索泰拉马斯的dFC.
- 调查改变的dFC与精神分裂症的临床特征之间的相关性.
主要方法:
- 在43名精神分裂症患者和31名健康对照中利用3.0特斯拉休息状态功能性MRI (rs-fMRI).
- 通过人类大脑图谱,将丘脑分为8个子区域.
- 用灵活最小平方方法计算每一个thalamus子区域的dFC.
主要成果:
- 与对照人群相比,精神分裂症患者表现出lamus和小脑,视觉,感觉运动和前皮层区域之间的dFC增加.
- 在 thalamus 的 dFC 和右状环之间发现了负相关性,以及发病的年龄.
结论:
- 在精神分裂症患者中,特定的泰拉木斯子区域显示了改变的dFC.
- thalamic失联性与精神分裂症的病理生理学有关.
