 entered the substance of the hemisphere. (Compare with fig. 3.) Somato-sensory 

 radiation (sr) entering the superior parietal convolution (PS), the visual radiation 

 in as much as it was interrupted forms a degenerated zone in the upper portion of 

 the external sagittal stratum of the parietal lobe (vr). Inferior parietal convolu- 

 tion (PI) with the Sylvian fissure, the latter receiving a few afferent fibers. 

 (Compare with x in figs. 52-54.) A bundle of callosal fibers in the tapetuni, 

 and a bundle of the efferent fibers in the internal sagittal stratum degenerated.
