Figure 2:

Individual participant ROIs and mean BOLD fMRI responses. Eye movements were used to classify each trial as an eye trial (greater time spent fixating the eyes of the talker) or a mouth trial (greater time spent fixating the mouth of the talker). A. Eight individual hemispheres from four participants showing the pSTS mouth ROI, defined as regions of the anatomically-defined posterior STS (pSTS) that responded more strongly to mouth trials. Group map shown in Figure 4. B. Response across all 34 participants in the pSTS mouth ROI to mouth trials (left trace) and eye trials (right trace). Center trace shows the mean and flanking lines show the SEM. Trial duration was 2 seconds (gray box). C. Location of the pSTS eye ROI, defined as regions of the pSTS responding more strongly to eye trials. D. Response across participants in the pSTS eye ROI for the two trial types.
