The inferior cerebellar peduncles (corpus restiformis) pass down- 

 ward and inward to the level of the medulla, where the fibers which 

 form them separate into three groups: the first form the external

 The cortex of the cerebellum is divided into two layers: the 

 external, or molecular layer ; and the internal granular, rust-colored, 

 or nuclear layer. The external layer is made up of two kinds of cells : 

 star-shaped and basket cells. The neuraxons of the stellate cells enter
