Fig. 46, Experiment II. The lesion (L) reaches the ventral portion of the 

 puiamen (Put) after penetrating through the external capsule and interrupting 

 a bundle of fibers of the anterior commissure. First appearance of the central 

 sulcus (C; its lower extremity; compare with fig. 2.) The middle "fan" of the 

 thalamo-cortical radiation (sr) fully developed enters the cortex lining the central 

 sulcus as well as that of both the precentral (CA) and of the postcentral convolu- 

 tion (CF) and the frontal operculum (OF). Sylvian fossa (FS), globus pallidus 

 (Gp), caudate nucleus (Nc), superior temporal convolution (T^).
