在闭着眼睛的放松和清醒状态下，8 - 12hz的神经振荡是主要的节律，在顶叶-枕叶区域最为突出。静息状态(RS) α与处理速度有关，也被认为是网络如何处理信息的核心。不幸的是，RS闭眼（EC）检查只能用于那些闭着眼睛可以长时间保持清醒的人。因此，婴儿、幼儿和智障人士通常被排除在RS alpha研究之外。先前的研究表明，在黑暗的房间里睁着眼睛测量RS α是传统RS EC检查的可行替代方案。为了进一步探讨这一点，使用脑磁图记录了6.9-12.6岁典型发育儿童（TD; N = 37）和自闭症谱系障碍儿童（ASD; N = 30）的RS EC和RS暗室（DR）睁眼α活动。结果显示RS - EC和DR峰α频率（α功率最强的频率，类间相关系数(ICC) = 0.83）具有良好的信度。后验α功率的ICCs略低（ICCs为0.70 s）， DR组的后验α功率比EC组降低了约5%。在TD组和ASD组之间没有观察到EC和DR关联的差异。最后，年龄与EC和DR α峰频率相关。因此，研究结果表明，在经常被排除在RS电生理研究之外的人群中，DR检查是获得RS α测量的可行方法。
In a relaxed and awake state with the eyes closed, 8–12 Hz neural oscillations are the dominant rhythm, most prominent in parietal‐occipital regions. Resting‐state (RS) alpha is associated with processing speed and is also thought to be central to how networks process information. Unfortunately, the RS eyes‐closed (EC) exam can only be used with individuals who can remain awake with their eyes closed for an extended period. As such, infants, toddlers, and individuals with intellectual disabilities are usually excluded from RS alpha studies. Previous research suggests obtaining RS alpha measures in a dark room with the eyes open as a viable alternative to the traditional RS EC exam. To further explore this, RS EC and RS dark room (DR) eyes‐open alpha activity was recorded using magnetoencephalography in children with typical development (TD; N = 37) and children with autism spectrum disorder (ASD; N = 30) 6.9–12.6 years old. Findings showed good reliability for the RS EC and DR peak alpha frequency (frequency with strongest alpha power; interclass correlation (ICC) = 0.83). ICCs for posterior alpha power were slightly lower (ICCs in the 0.70 s), with an ~ 5% reduction in posterior alpha power in the DR than EC condition. No differences in the EC and DR associations were observed between the TD and ASD groups. Finally, age was associated with both EC and DR peak alpha frequency. Findings thus indicate the DR exam as a viable way to obtain RS alpha measures in populations frequently excluded from electrophysiology RS studies.
