THE PONS AND THE CEREBELLUM.

As will be seen from this, the cortex of the cerebellum is an exceedingly 

 complicated apparatus, an apparatus which is adapted for uniting elements 

 of very different character and origin. 



In the section presented in Fig. 208 one may note: 1. That the fibers 

 from the central white matter of the cerebellum pass into the cortex in

thick medullated fasciculi. 2. That in the region of the granular layer 

 only curved pieces of these fibers are shown. 3. That these form a true 

 plexus of medullated fibers lying in the sagittal plane below and between the 

 Purkinje cells. Eunning in the same direction are separate, thin, medullated 

 fibers, — not shown in the figure, — which lie just beyond the bodies of the 

 Purkinje cells in the molecular layer.
