Figure 1.
Significant areas of activation for BCV > TRV and PRV > TRV. (A) 3D rendered MR image of chimpanzee brain. Arrow directions refer to ascending slices, and x, y, and z-axes indicate orthogonal planes (sagittal, coronal, and axial, respectively). (B and C) PET activation overlaid on MR images of representative chimpanzee brain. x, y, and z refer to planes described in (a) and measurements refer to depth from dorsal tip of brain (z; dorsal to ventral), or distance from frontal pole (y; anterior to posterior). Top images are 3D rendered MR images of chimpanzee right (RH) and left hemispheres (LH) with significant (t ≥ 4.31) PET activation overlaid. Lower images depict significant BCV > TRV (a), and PRV > TRV (b), PET activation overlaid on axial (lower left) and coronal (lower right) MR images. See Table 1 for a complete list of regions with significant BCV > TRV and PRV > TRV activation.
