英文原文摘要全文
Aims Obsessive‐compulsive disorder (OCD) is associated with abnormalities in large‐scale brain network dynamics. Conventional electroencephalography (EEG) captures local oscillatory activity but does not characterize spatiotemporal propagation patterns. This study investigates cortical traveling waves, which index directional information flow across the cortex, to determine whether they provide novel insights into altered neural communication in OCD. Methods Resting‐state (eyes‐closed) and task‐based (Go/NoGo, Flanker) EEG were recorded from 25 individuals with OCD and 27 healthy controls (HCs
