Confirmation of a Useful Dark-Room Resting-State Procedure: Periodic and Aperiodic MEG Activity in Children.

ABSTRACT: In a previous paper, we showed in children 6-12 years old that a resting-state (RS) eyes-open dark room (DR) task provides RS parietal-occipital alpha measures similar to those obtained using the standard RS eyes-closed (EC) exam. Results provided initial evidence that the RS DR procedure is feasible and useful with populations often excluded from electrophysiology RS studies, such as participants who cannot remain awake with their eyes closed or cannot remain still for an extended period. The present study extended the DR and EC comparisons to a much larger sample of children spanning a wider age range and expanded the analysis strategy to examine RS aperiodic measures (offset and slope [exponent] of the power spectrum) and to evaluate 15 distinct brain regions rather than just the previo
