Fig. 63, Experiment VI. This figure shows under the same magnification as 

 figures 58-61, and 62, finer relations of the incoming association fibers in the 

 precentral "motor" cortex originating from the postcentral granular cortex 

 (that is, from a convexity of the middle third of the postcentral convolution). 

 All degenerated fibers exhibit a course identical with that of the "radiated" 

 bundles and distinct from that of the exogenous thalamic fibers of the same 

 region (figs. 61, 62).
