Figure 5. A schematic summary of the extrinsic and intrinsic speech and non-speech networks.

Figure 5

The extrinsic areas are labeled with blue letters, the intrinsic with red letters. Areas of the speech network are marked by solid boxes, areas of the non-speech sound network by dotted boxes. The summary is based on the characteristics of independent components (ICs) IC1–IC8. Extrinsic areas are based on the correlation and overlap of the ICs with the intersubject correlation (ISC) map. Speech and non-speech brain areas are based on the similarity of the time-courses of the ICs to the speech and non-speech regressors, and on functional connectivity analysis. Abbreviations: MTG = middle temporal gyrus, IN = insula, SFG = superior frontal gyrus, SFGmed = superior frontal gyrus medial part, MFG = middle frontal gyrus, IFG = inferior frontal gyrus, TP = temporal pole, IPL = inferior parietal lobule, SMG = supramarginal gyrus, CC = cingulate cortex, Cun = Cuneus, PreCun = PreCuneus, ant = anterior, post = posterior, sup = superior, inf = inferior, trans = transitional.
