(A) 3D rendering of voxel intensity map indicating the weighted contributions of whole brain gray matter voxels to the decision function of NR and MR chimpanzees. Color bar indicates the intensity values with colors at the extreme ends reflecting increased contribution to the classification function. (B) Number of MR and NR chimpanzees correctly and incorrectly classified based on the SVM algorithm (C) Number of standard nursery-reared chimpanzees (SR) and those that received some early social stimulation (RC) classified correctly or incorrectly as nursery-reared.
