科学领域:

神经科学是一个神经科学.
心理学心理学心理学
自闭症研究自闭症研究

背景情况:

内感觉,身体的内部感官意识,在自闭症谱系障碍 (ASD) 中经常受到损害.
亚临床自闭症特征,ASD症状的较温和形式,在一般人群中普遍存在,并可能为ASD病理生理学提供见解.
了解与自闭症特征相关的整感觉的神经支对于识别潜在的生物标志物和治疗点至关重要.

研究的目的:

研究健康成年人休息状态功能连接 (rsFC),整感受和自闭症特征之间的关系.
探索一般人群中神经网络变化如何与自闭症的核心特征有关.

主要方法:

62名健康的年轻人接受了功能磁共振成像 (fMRI) 评估rsFC.
参与者完成了自报告测量自闭症特征和整体感知能力 (准确性和敏感性).
统计分析检查了rsFC,整感测量和自闭症特征得分之间的相关性.

主要成果:

发现自闭症特征和侧腹前岛和前带皮层之间的rsFC之间存在负相关性.
在涉及小脑,补充运动区域和视觉区域的网络中,互感准确度和灵敏度与rsFC正相关.
在整感受性大脑网络内减少的rsFC部分介导了整感受和自闭症特征之间的负面关系.

结论:

这些发现表明,减少整感受性大脑网络连接性与健康个体中更高的自闭症特征有关.
自我报告和神经连接测量都有助于理解整体感应和自闭症特征之间的联系.
这些结果突出了整感处理和相关的神经通路在自闭症特征的表现中的作用.
