Fig. 77, Experiment VI. In this experiment as well as in Experiment V the 

 convexity of the postcentral convolution (CP) was destroyed. The lesion (L) 

 is confined either to the cortex alone or it extends for a short distance into the 

 subjacent white substance (1 mm.). Besides numerous association and callosal 

 fibers, a considerable number of fine, medium sized and a few coarse efferent 

 fibers are degenerated; the latter descend into the internal capsule, as the 

 figure shows, in the lateral half of the cerebral peduncle and farther caudal- 

 ward. None of the postcentral efferent fibers terminates in the peduncle, in the 

 substantia nigra, in the red nucleus, or in the caudate nucleus, few only enter- 

 ing the globus pallidus. (Compare with Experiments VII, VIII, IX, figs. 78-85.) 

 Precentral convolution (CA), Sylviaji fossa (FS).
