Surface description of the ROI parcellation.

Regions	Description
Superior temporal sulcus (STS)	The FreeSurfer STS ROI is bounded anteriorly by the temporal pole, medially by the STG, laterally by the MTG, and posteriorly by the IPL. We divided this region into roughly equal thirds along the rostro-caudal axis (STGp, STGm, STGa)
Superior temporal gyrus (STG)	The FreeSurfer STG ROI runs from the rostral edge of the STS to the supramarginal gyrus. It is bounded medially by the SF. We divided this region into roughly equal thirds along the rostro-caudal axis (STGp, STGm, STGp)
Planum temporale (PT)	The FreeSurfer PT ROI is bounded anteriorly by the TTS, medially by the SF, laterally by the STG, and posteriorly by the supramarginal gyrus. We divided this region into roughly equal thirds along the rostro-caudal axis (PTp, PTm, PTa)
Transverse temporal sulcus (TTS)	The FreeSurfer TTS ROI is bounded posteriorly by the PT and anteriorly by the TTG. We divided this region into two halves along the medial-lateral axis
Transverse temporal gyrus (TTG)	The FreeSurfer TTG ROI is bounded rostrally by the rostral extent of the TTS, caudally by the caudal portion of the insular cortex, laterally by the STG and medially by the SF. We divided this region in roughly equal halves along a medial-lateral axis
Caudal segment of the Sylvian Fissure (SF)	The FreeSurfer posterior SF ROI runs from the lower end of the central sulcus to the end of the posterior ascending ramus (Dahl et al., 2006). We divided this region in roughly equal halves
Planum polare (PP)	Unedited version of FreeSurfer. It is bounded rostrally by the temporal pole, caudally by the TTG, and medially by the parahippocampal gyrus
