Serial transverse sections of the brain stem

Pons.

At this level and in the remaining views of this series another brain has been substituted for the specimen used thus far. The cut surfaces are unstained, inasmuch as there is sharper contrast between gray and white matter at higher levels of the brain stem and in the region of the basal ganglia.
