Background/Introduction: Concurrent electroencephalography and resting-state functional magnetic resonance imaging (rsfMRI) have been widely used for studying the (presumably) awake and alert human brain with high temporal/spatial resolution. Although rsfMRI scans are typically collected while individuals are instructed to focus their eyes on a fixated cross, objective and verified experimental measures to quantify degree of vigilance are not readily available. Electroencephalography (EEG) is the modality extensively used for estimating vigilance, especially during eyes-closed resting state. However, pupil size measured using an eye-tracker device could provide an indirect index of vigilance.

同时静息状态脑电图、功能性磁共振成像和眼动仪方法的集成，以确定和验证脑电图警戒措施

背景/介绍：并发脑电图和静息状态功能磁共振成像 (rsfMRI) 已被广泛用于研究（大概）清醒和警觉的人脑，具有高时间/空间分辨率。虽然 rsfMRI 扫描通常是在个人被指示将眼睛集中在固定的十字架上时收集的，但不容易获得客观和经过验证的实验措施来量化警惕程度。脑电图 (EEG) 是广泛用于估计警惕性的方式，尤其是在闭眼休息状态下。然而，使用眼动仪测量的瞳孔大小可以提供一个间接的警惕指数。
