Supplementary Figure 9: Reliability-matched ROI analyses using data from all 5 macaques tested in Experiment II.

Fig 3f shows ROI analyses for two macaques with similar response reliability to humans. Here we show results from all five macaques and subsample the human data to match reliability. a, Reliability (Pearson correlation) of stimulus-driven fMRI responses from each human and macaque subject per block of data (same format Fig 2a). Error bars show 1 standard deviation across subsampled sets of runs. b, Reliability of macaque and human data, as well as subsampled human data designed to best match the reliability of macaques (same format Fig 2b). c, d, ROI analysis of voxels preferentially responsive to voiced (c) or noise-vocoded calls (d). Left plots show group-averaged responses to voiced and noise-vocoded calls (averaged across two matched sound intensities: 70&75 dB). Right plots show a measure of selectivity applied to group or individual subject responses (same format as Fig 3f). Error bars reflect one standard error (median and central 68%) of the bootstrapped sampling distribution. Bootstrapping was performed across runs for individual subject analyses, and across both subjects and runs for group data.
