Topic: temporal autocorrelation

Spontaneous neural dynamics manifest in periodic and aperiodic activity, which are hierarchically organized and intrinsic to different brain areas, in a way thought to mediate information processing of environmental stimuli during wake. Particularly prominent are intrinsic neural timescales, a measure of temporal autocorrelation, which reflect functional significance for cognition, changes in gene expression, and modulations in brain disorders. To date, however, less is known about the regional distribution of neural timescales at the whole-brain level during sleep in humans, where the need fo
