Intraoperative ECoG of musical and syntactic complexity

(A and B) Results from a multiple linear regression model plotted as colored electrodes on the cortical surface, modeling the impact of the interaction between sequence complexity and position in the sequence for (A) music processing and (B) sentence processing, on the broadband gamma activity (BGA; 70–150 Hz) 100–400 ms following each tone/word onset. Electrode color is scaled based on beta values, with high complexity in orange and low complexity in purple. The MRI-derived mask of pathological tumor tissue is marked in opaque crimson. Exemplar high and low complexity stimuli are highlighted.

(C) Effects of syntactic complexity during language production in the auditory repetition task, localized to inferior frontal cortex. Colored bar represents periods of significant difference (FDR-corrected, q < 0.05). Electrode of interest is denoted via black dot.
