INTRODUCTION TO NEUROLOGY 



Fig. 124. Section from the cerebral cortex of a human infant from the 

 postcentral gyrus (gyrus centralis posterior), with the neurons impregnated 

 by the method of Golgi. The figure is taken from Ramon y Cajal's His- 

 tology of the Central Nervous System, and the layers are numbered accord- 

 ing to his system. Layer 1 corresponds to Brodmann's first layer (Fig. 

 127); layer 2, to his second layer; layers 3 and 4, to his third layer; layer 5, 

 to his fourth layer; layer 6, to his fifth layer; and layer 7, to his sixth layer.
