Brain areas with differences in functional connectivity between stuttering subjects and controls.

Abbreviations: B, bilateral; FP, frontal pole; IFGop, operculum part of inferior frontal gyrus; IPL, inferior parietal lobule; L, left; MCC, middle cingulate cortex; MNI, Montreal Neurological Institute; MPFC, medial prefrontal cortex; OP, occipitoparietal region; OT, occipitotemporal region; PCC, posterior cingulate cortex; PFC, prefrontal cortex; PMC, premotor cortex; R, right; ROI, region of interest; STG, superior temporal gyrus.Note: Positive t value represents increased functional connectivity in stuttering group, while negative t value denotes decreased functional connectivity.
