Fig 2. Band-power analysis.

(A, D, G, I, K) Effect sizes (Cohen’s d) of the band power change of “before-during” and (B, E, H, J, L) “before-after” across five frequency bands. (C, F) Time series of the average band-power in broadband (1-70Hz) for Patient 3 and Patient 5 respectively. Positive effect size denotes decrement in absolute band power. Topographical maps are ordered as delta, theta, alpha, beta and gamma. The frames surrounding topographical maps signify difference in the respective states they are representing. For instance, Fig 2C has yellow, red, and blue colours over laid across before, during, and after epochs respectively and topographical maps in Fig 2A has “yellow-red” colour frame representing the effect size between “before-during” states.
