THE NERVOUS SYSTEM 



1. Molecular or tangential fibre layer. 



2. Outer polymorphous cell layer. 



3. Small pyramidal cell layer. 



4. The layer of granule and large pyramidal cells. 



5. The outer stripe of Baillarger (great pyramidal plexus). 



6. The granule cell layer. 



7. The inner stripe of Baillarger (polymorphous plexus). 



8. Inner polymorphous cell layer. 



The special characteristics of this visual area are the abundance 

 of tangential fibres,* as evidenced by the prominent stripes of Bail-

* The corresponding abundance of granule cells and tangential fibres is 

 suggestive of a close relation between these elements, the tangential fibres prob- 

 ably arising in large part from the terminal division of centripetal neuraxes.
