Fig. 373A. Schematic diagram of the different layers of the cerebral cortex. (After Ramon y 

 Cajal, 1890.) The tangential fibres, Vicq d'Azyr's ribbon, Baillarger's internal and external striae, 

 and the white substance are stained red ; M, molecular layer; pPy, layer of small pyramidal cells; 

 gPy, layer of large pyramidal cells; Pm, layer of polymorphous cells.

 cortex. The dotted lines separate the four cellular layers of Cajal. <S6, white substance.
