Note. 1. Red = Middle frontal gyrus (MFG); Blue = Opercular part of inferior frontal gyrus (IFG); Green = Transverse temporal gyrus (TTG); Purple = Planum temporale (PT); Clear = Primary motor cortex.
Significant regressions:
Speech rate – Right MFG, R2 = .94
Speech rate – Right IFG, R2 = .76
Mean length of utterance – Left IFG, R2 = .85
Content – Left TTG, R2 = .75
