Paths within the lower brainstem of the rhesus monkey form a system in three approximately orthogonal axes -- front-to-back (blue), left-to-right (red), and head-to-tail (green). Here, MRI shows the basic form of the vertebrate nervous system, recognized for a century in simpler species. Compared with the forebrain, the brainstem structure shown here is relatively un-curved, and illustrates simultaneous crossing of paths in all three cardinal axes. Two dimensional grid structure is formed by the crossing of fibers in planes defined by each pair of directions (red-green, red-blue, blue-green).
