Time-frequency results. a Time-frequency plots showing delta changes in normalized power in go and stop trials (left) for patients with MwoA and healthy controls for the selected electrode (Cz). Black dotted squares indicate the time-frequency region in which theta power in stop trials was significantly higher in patients with MwoA than in healthy controls. Scalp topography maps show the spatial distribution of theta power (4–8 Hz) in go and stop trials between 350 and 500 ms. The color scale indicates spectral power in SD. b Means and standard errors (SEs) of the delta power (4–8 Hz) between 350 and 500 ms at Cz in the two groups. **, p < 0.01
