 Area of the primary histological lesion compared with the exactly homotopic 

 region in the same section. Small densely stained cells are seen around the 

 primary lesion while in the contralateral cortex fewer cells seem to take the 

 stain than in regions closer to the area of maximal electrical discharge. Methyl 

 green pyronin stain. Magnification X 75.
