A, Position of the inclusion masks used in the macaque tractography of the IC, the SLF, the CB, and the CC. B, Inclusion masks used in the human tractography. The slice coordinates are relative to MNI152 standard space and are in millimeters (coordinate [0, 0, 0] corresponds to the AC). The CC inclusion mask is not displayed; it corresponds to a single planar ROI containing the whole anterior half of the CC at coordinate X = 0. C, Location of the three injection sites from the tracing data displayed on the FA map of macaque MAC1a (top) and human MNI standard space (bottom). Red represents vmPFC; green, cOFC; blue, lOFC. D, Tracking strategy common to both macaque and human experiments. Streamlines are only retained if they cross inclusion masks and excluded if they do not or if they cross one or more exclusion mask. When two inclusion masks are used, they are required to be crossed in a specified order (anterior to posterior in all our experiments).
