Left column: the averaged brain, which served as a template for structural delineation. Red crosshairs on transverse and sagittal view (middle and bottom) indicate the positions of the other planes. Right column: the atlas file is overlaid onto the template file. Delineation and refinement were primarily performed using the coronal sections, though further refinement was done in both the sagittal and axial planes. Top row: annotated over the left hemisphere of both coronal images are the structural regions that the label tags represent. Middle and Bottom row show transverse and sagittal views respectively; CC, corpus callosum and external capsule; cg, cingulum; cor, cortex; cp, cerebral peduncles; DG, dentate gyrus; eml, external medullary lamina; f, fornix; fr, fasciculus retroflexus; hyp, hypothalamus; hpc, hippocampal CA subfields; LV, lateral ventricle; ml, medial lemniscus; MM, mammillary bodies; opt, optic tract; PAG, periaqueductal gray; 3 V, third ventricle.
