Not much has changed from
the last section.
We have indicated some tufts of choroid
plexus in the third and lateral ventricles.
At this point, you should have fibers crossing between the two hippocampi,
forming the commisure
of the fornix (hippocampal commisure). They aren't distinctly visible
because they are blending with fimbria
and fornix
fibers. The internal capsule is very prominent. The ventral aspect of the
3rd ventricle is fairly small.
