The Morphogenic Mapping of the Brain and the Design of the Nervous System

Figure 2

(a) The gridded cap from Figure 1(a) rotated 90 degrees clockwise. (b) A close up view of the apex of (a). The zone at the base of the frontal lobe is labeled as the Primary motor sensory area (colored a darker pink). The zone at the top of the parietal lobe is labeled as the primary somatosensory area (colored a darker purple). These two areas extend to 180 degrees of the 360 degrees around the apex of the sphere. For clarity only one half of this is labeled (half of the bilateral form). Labeling would be mirrored in the 90-degree section below the labeled section. (c) The arcs from the gridded sphere are shown in the top view of the mature brain, with extruded cross-sections showing their folding, resulting from involution through the blastopore. Half of the primary motor area is labeled on the left (would be mirrored on the right). Half of the primary somatosensory area is labeled on the right (would be mirrored on the left).
