Selectivity across face and object images inside and outside the pMFP. Site-by-site image responses were normalized by the site's maximum absolute response across all images and then ranked using independent data (within face or nonface image groupings; see Materials and Methods) before averaging over all sites and both monkey subjects in each of the three anatomical regions described previously (“In,” “Near,” and “far”; based on distances of 1 and 2 SDs of the fit isotropic Gaussian model). The responses to all face (black curves) and nonface objects (blue) are shown for sites in the “in,” “near,” and “far” regions. In the pMFP, the best driving face image gave a greater response than the best driving object exemplar; and outside the pMFP (middle and right panels), the response to the best driving face image was far exceeded by the response to the best driving object exemplar. To prevent any bias, images were rank-ordered on a held-out set of trials, and the remaining trials were used for plotting rank-ordered responses.
