Fig 6. Relation between high gamma activity (HGA) and voice perception.

Fig 6

Across all electrodes of all patients, average standard increases in HGA were statistically compared between success and error trials. In the inferior frontal gyrus (IFG), the voice-induced standardized increase in HGA was significantly higher in correct trials than in incorrect trials in the low-incongruent condition (p = 4.76E-9, two-tailed paired t-test). In the superior temporal sulcus (STS), the voice-induced standardized increase in HGA was significantly higher in correct trials than in incorrect trials in the high-incongruent condition (p = 0.0291, two-tailed paired t-test). N represents the number of electrodes in the IFG and STS. The y axis shows the average percentage of standardized power change in HGA. Error bars indicate standard error of the mean.
