Temporal Lobe and Auditory Areas 



[CHAP. 



The appearances which serve specially to distinguish this field of cortex are those pre- 

 sented by the giant cell layer. Compared with the transverse temporal gyri the extra large 

 cells noted there have suffered a very pronounced reduction in number, instead of from 8 to 12 

 being visible in every transverse mm. of substance, there are but 3 to 5. The prevailing 



Fie. 14. 



Some of the largest cells to be found in area No. 2, that is on the free surface of the superior temporal convolution. 

 Compared with corresponding cells in area No. 1, figure 13, they are much smaller and more poorly represented as 



regards chromophilic elements. 

 The smaller cell, lying in the upper part of the figure, may be taken as representative of the size of the largest 



pyramidal elements distributed over the general temporal cortex; area No. 3. 

 From a crush specimen; thionin staining; Zeiss oil-immersion apochromatic lens, 2mm. 



cells are those which I have alluded to under the name large pyramidal, and these are 

 appreciably more numerous than they were in the transverse gyri (text-figure 14). Small 

 pyramidal cells are also dotted about here and there. 



No differences can be made out between the stellate layer here and in the transverse 

 temporal gyri.
