Beta oscillations in the naive state. A, Example power spectra and time series data from the naive state identified with (solid black) and without (dashed gray) significant beta oscillatory activity. B, Averaged power spectra across all recordings for each subject in the naive state. Bold lines show means and shaded areas show ± 1 SD of flattened power spectra for subjects P1 (blue), P2 (gray), and P3 (red) in the GP in the naive state. Arrows demarcate median frequencies of beta oscillations for each subject. The cyan shaded area corresponds to the beta band. C, Number of recordings with (solid) and without (hashed) detected beta peaks for each subject.
