Fig. 2. CSVA model voxel-wise prediction accuracy scores mapped onto cortex.

a Voxels where activity was significantly predicted by the Combined Semantic, Valence and Arousal (CSVA) model are shown on cortical maps for all 6 subjects. For each voxel, prediction accuracies were calculated using the z-transformed correlation between the CSVA model predicted time-course and the recorded BOLD time-course for the validation dataset. Significance was assessed by permutation testing, see Methods for details. The CSVA model significantly predicts validation BOLD time-courses across much of OTC. This was consistently observed across subjects. b Prediction accuracy scores for subject 1; the cortical map is cropped (top) to zoom in on OTC. In addition, prediction accuracy scores are projected onto inflated lateral (bottom left) and ventral (bottom right) cortical surfaces. Note: Regions of interest (ROIs) are labeled in white, sulci in black.
