THE CEREBELLUM 521 



It is a remarkable fact that the only cells of the cerebellar cor- 

 tex which send their neuraxes into the white medulla are those of 

 Purkinje. All the other nerve cells appear to be so arranged as 

 to serve as association paths only, whereas the neuraxes of the 

 Purkinje cells may be said to form the projection paths of the 

 cerebellar cortex.
