Fig. 17. — Two neurons characteristic of neopallial cortex. At the 

 left is a pyramidal neuron (type I of Golgi) from the rabbit (after Cajal), 

 whose axon (a) enters the white matter (<^), first giving off collateral 

 branches (c) to the deeper cortical layers. The larger dendrites (d) are 

 directed toward the brain surface. At the right is a neuron of type II 

 from the cat (after (Kolliker), whose short axon (a) branches freely and 

 terminates close to the cell body.
