Some writers l lay much stress on the difference of structure 

 of the cortex in different regions of the hemisphere. It is true 

 that, in the non-excitable or sensory regions, the cortex is thin- 

 ner and perhaps less highly organized ; but here are met the 

 same elements as form the cortex in the motor region (centre, 

 for the arm, for instance). (See Fig. 150.) Even the giant-cells 

 are found less numerously than in the motor regions. Another 

 fact demands attention, that is, that the structure of the cortex 

 is the same at the bottom of a fissure as on the surface of a 

 convolution, and for this reason lesions of the sides and bottom 

 of fissures should receive as much attention as those of the 

 surface of the convolutions, implicating, as they do, equally im- 

 portant structures.
