在自闭症谱系障碍中,动态大脑活动和功能连接的性别异质性
概括
自闭症谱系障碍 (ASD) 显示了大脑功能中的性别差异. 动态分析揭示了ASD的男性和女性不同的大脑活动和连接模式,突出了性别异质性.
科学领域:
- 神经科学是一个神经科学.
- 发育神经科学的发展神经科学.
- 精神病学是一个精神病学.
背景情况:
- 性异质性经常在自闭症谱系障碍 (ASD) 中观察到,通常与静态大脑功能差异有关.
- 了解动态大脑活动和功能连接对于区分性别之间的ASD表型至关重要,因为复杂的诊断性互动.
研究的目的:
- 用动态视角研究自闭症谱系障碍 (ASD) 大脑中的性别异质性.
- 探索ASD中与性别相关的大脑活动和功能连接的动态特征.
主要方法:
- 分析了128名自闭症和128名典型发育控制 (TC) 试验对象 (64名男性/64名女性) 的休息状态功能磁共振成像 (fMRI) 数据.
- 使用滑窗方法来估计低频波动 (dALFF) 和动态功能连接 (dFC) 的动态振幅.
- 采用双向差异分析 (ANOVA) 来检查ASD与性别相关的变化.
主要成果:
- 对于dALFF,在左前带带皮层/中前额皮层 (ACC/mPFC) 和左前皮层中发现了显著的诊断性相互作用效应.
- 在左ACC/mPFC与其他几个大脑区域 (右ACC,左后中环,左前,右中环,左下额头环,三角部分) 之间的dFC变异中也观察到显著的诊断性相互作用效应.
结论:
- 这项研究从动态角度揭示了大脑活动中的性别异质性和ASD中的功能连接性.
- 这些发现为进一步调查ASD中的性别差异提供了新的证据.
- 动态分析提供了超越静态措施的ASD异质性的更细致的理解.

77
Autism spectrum disorder (ASD) is a neurodevelopmental condition marked by persistent deficits in social communication and interaction alongside restrictive and repetitive behaviors or interests. ASD is sometimes accompanied by intellectual impairment.
These core symptoms manifest differently among individuals, ranging from mild to severe. The disorder's complexity extends beyond its clinical presentation, encompassing a diverse range of biological, cognitive, and sociocultural influences.

Modeling, a key technique in therapy, uses observational learning to help clients acquire and practice new skills by watching therapists demonstrate desired behaviors. This approach, rooted in Albert Bandura's concept of vicarious learning, plays a significant role in therapeutic interventions for various psychological conditions, including social anxiety, ADHD, and depression.
