亚临床精神病经历与突出网络 (SN) 的功能连接性增加有关,特别是涉及背前带状皮质和前半岛. 这表明SN
科学领域:
- 神经科学
- 精神病学
- 认知科学
背景情况:
- 在一般人群中,精神病经历 (PEs) 发生在临床下.
- 异常突出假设认为突出网络 (SN) 是PE的关键.
- 在背部前带皮层 (dACC) 和前带皮层 (AI) 中固定的SN,协调内外世界.
研究的目的:
- 在一般人口样本中调查SN的功能连接性 (FC).
- 检查SN在PE的发展和维护中的作用.
- 通过SN功能连接了解PE的病因.
主要方法:
- 来自84名普通人群的休息状态功能连接 (rsFC) 数据.
- 使用社区心理经验评价-正面量表 (CAPE-15) 量化PEs.
- 使用ENIGMA HALFpipe和FSL进行了dACC和AI的种子相关性分析,并进行了FDR校正.
主要成果:
- 增加的PEs与关键的SN节点 (AI,dACC) 的显著超连接性相关.
- 在SN节点显示超连接到默认模式,中央执行,视觉,听觉和腹部注意力网络.
- 特定的超连接区域包括丘脑,副海马环和额头极.
结论:
- 这些发现支持SN在一般人群中发展和维持PEs的关键作用.
- SN的超连接性可能是无关紧要的刺激的基础.
- 这表明在患有PEs的个体中增加了注意力和寻找认知解释.
