Trial type related differences in theta power and mPFC-STN phase coherence. (A and B) Cue and response aligned time evolving theta power changes averaged over all STN (A) and mPFC (B) electrodes during the Go, Conflict, and NoGo trials. Time points exhibiting a significant difference between trial types (P < 0.05, corrected for multiple comparisons, permutation test) are denoted by coloured horizontal bars denoting which comparison was made. (C) Normalized mPFC-STN phase coherence averaged across all mPFC-STN electrode pairs and across all correct trials. Mask indicates time-frequency regions exhibiting significant differences from baseline at P < 0.05, corrected for multiple comparisons, permutation test. NoGo trials were excluded from the response aligned analysis. (D) Same data as in C but averaged across the theta band and plotted separately for the Go, Conflict, and NoGo trials. Time points exhibiting a significant difference between trial types are denoted as in A. In general, conflict and response inhibition involved higher levels of theta power and mPFC-STN phase coherence prior to the response.
