Open-eyed meditation suppresses functional connectivity in EEG across a broad frequency range

bioRxiv (Cold Spring Harbor Laboratory) May 18, 2026 Vinod Jiani, Ankan Biswas, Supratim Ray

Abstract Functional connectivity (FC) is a statistical measure that reflects the degree of phase consistency between two signals and provides insights about potential interactions between two brain regions. Previous studies have reported conflicting results on the effect of meditation on FC, with some showing enhancement while others reporting suppression of FC. However, even though meditation...

Simultaneous enhancement of stimulus-induced and stimulus-free gamma in open-eye meditators.

Imaging neuroscience (Cambridge, Mass.) 2026 Ankan Biswas, Srishty Aggarwal, Kanishka Sharma et al.

Visual stimuli-induced "narrowband" gamma oscillations (30-70 Hz) are generated due to excitation-inhibition interactions and are linked to attention/binding. These oscillations attenuate with aging and neurodegeneration, potentially indicating declining inhibitory function. In contrast, meditation enhances endogenous stimulus-free gamma (power in a broad frequency range above 25 Hz). However,...
