Viewing the Cerebellum |
Now that you know the inputs to the cerebellum, we need to learn WHERE in the cerebellum each afferent terminates. To understand this distribution scheme, you need to know the conventional way in which the gross cerebellum is viewed. Past experience has shown that this is a bit confusing.
Pictured to the right
are two views of the brain that show the location and shape
of the cerebellum. (A) is a medial view while
(B) is a lateral view. A portion of the occipital
cortex that lies above the cerebellum has been removed in
order to see the dorsal aspect of the cerebellum. If we were
to "lop off" the brain stem and cerebellum at the spot
marked "cut" in A on a WHOLE (not one-half)
brain, we would see what is pictured in the dorsal view,
lower left (C). Now you can see the midline region of
the cerebellum and the two (right and left) hemispheres.
