FIGURE 3-6

     This is a lateral view of the brain (we are looking medially), with the putamen and globus pallidus (together = the lentiform nucleus) removed. Take a look at Figure 1-42 to remind yourself of the relationships between all these structures. Because of what has been removed we can see the fibers of the internal capsule. The colored ones are part of the descending motor system, but just posterior to them a single shaded arrow shows the course taken by the ascending fibers of the somatic sensory system that we have been tracing.
