GANGLIONAR GRAY MATTER.

It is filled with white fibers, which issue from its open anterior 

 end, called the hilus, and form the greater part of the brachium 

 conjimctivum cerebelli. It also receives many axones from Pur- 

 kinje's cells and, thus, forms a relay in the common sensory 

 path. 



The small ganglia are just visible to the naked eye under 

 favorable conditions (Fig. 84). One of these, a club-shaped mass,

the cork-like nucleus emboliformis, partly closes the hilus of the 

 dentate nucleus. Medial to that is an elongated antero-posterior 

 ganglion, bulbous behind, called the nucleus globosus. The third 

 nucleus is in the anterior end of the worm, just above the fastigium 

 of the fourth ventricle. It is called the nucleus of the highest
