FIGURE 2.25 The corpus callosum This large band of neural fibers connects the two brain hemispheres. To photograph the half brain above left, a surgeon separated the hemispheres by cutting through the corpus callosum (see blue arrow) and lower brain regions. The high-resolution diffusion spectrum image above right, showing a top-facing brain from above, reveals brain neural networks within the two hemispheres, and the corpus callosum neural bridge between them.
