Figure 4

Group average normalized changes in (frontal EEG)–STN LFP wavelet coherence. (A, left) Coherence spectrogram for the slow (top), medium (middle), and fast (bottom) trials. Changes were found relative to a 1-sec long time period between trials during which all dots moved randomly in any direction. (A, right). Differences between slow and fast trials were significant (top, p = .023, permutation testing, unmasked area) as were those between the medium and the fast trials (middle, p = .031). Time series of percent change in theta band (4–8 Hz) coherence are also shown (bottom, mean ± SEM), with thick lines denoting significant time points between two trial types (color of line indicates which two trial types were compared, p = .003 for slow vs. fast comparison, p = .004 for medium vs. fast comparison, permutation testing). (B) Same as A but for response aligned data. (B, bottom right) Both slow and medium trials showed significantly higher theta coherence in the second preceding the response (p = .039 for slow vs. fast comparison, p = .009 for medium vs. fast comparison, permutation testing).
