MODULE 6
INPUT from the CEREBRAL CORTEX
We will now try to trace the pathways on our slides. But first lets look at two views that show how the cortical input is organized.
----- Figure 6-13 This view shows the broad origin of the cortical input to cerebellum. The descending pathway from the frontal lobe is colored violet in subsequent views and that from the other lobes is colored dark blue.
----- Figure 6-14 This view demonstrates how descending corticopontine fibers find their way into the medial 1/5 and the lateral 1/5 of the cerebral peduncle. Note the plane of Slide 30, which will be our next view.
Now we will trace these descending fibers downward, toward the basilar pons. You can call up these slides by using Figure 6-15.
