Sub-second fluctuations between top-down and bottom-up modes distinguish diverse human brain states.
Current biology : CB July 2, 2026 Youngjai Park, Younghwa Cha, Hyoungkyu Kim et al.
Information continuously flows between regions of the human brain, forming patterns that shift across states of consciousness, cognitive modes, and neuropsychiatric conditions. While functional magnetic resonance imaging (fMRI) reveals large-scale activity changes over seconds, the electrophysiological dynamics governing sub-second reconfiguration remain poorly understood. Here, relative phase...
