Region of interest analysis. Figure displays the a priori defined regions of interest within which significant differences in activation (p < 0.05) were identified for two key contrasts. Bar graph indicates relative mean percentage BOLD signal change as a function of facilitation, compared to the unfacilitated condition. PSTG = posterior superior temporal gyrus and PITG = posterior inferior temporal gyrus. * indicates significant changes in mean signal intensity (p < 0.05, FDR corrected) between conditions. Error bars indicate standard error mean.
