Rajyoga meditation in 18 long-term meditators is linked to more stable fast cortical dynamics, with stronger inhibitory gain control and higher beta1/beta2/gamma power.
- Why it matters: The neural mechanisms that stabilize immersive, absorption-like meditation states are unclear, especially how oscillatory organization and corticothalamic inhibition regulate arousal and conscious transitions.
- What they did: The study combined frontal EEG spectral power, temporal non-stationarity, and corticothalamic neural-field modeling during eyes-open rest versus Rajyoga meditation, then correlated model estimates with absorption and dissociation ratings.
- The result: Compared with rest, meditation increased beta1, beta2, and gamma power, reduced beta-band temporal non-stationarity, and model fitting indicated stronger cortical inhibitory gain with lower effective intracortical gain; inhibitory gain estimates related to absorption and showed trend links with dissociation.
