42 ATLAS OF NERVE CELLS 



(a) The direct cerebellar column of the spinal cord. The fibres are the neuraxons of 

 the cells of Clarke's column as shown in Fig. 4, page 31. They pass to the cortex of the 

 cerebellum, some of them decussating in the part of the cerebellum which lies above the 

 pons with similar fibres from the other side. No attempt is made in the diagram to show 

 this decussation (i).
