Fig. 49, Experiment II. Multiple lesions (L) in the globus pallidus and in 

 the internal capsule, practically separating the thalamus (Th) from the hemi- 

 sphere. The number of fibers of the thalamo-cortical radiation (sr) though still 

 considerable is less than in the preceding figures. The main flow of the somatic 

 sensory fibers is toward the central sulcus (the vestige of its cortex is visible 

 in the upper corner of the figure as a small oval area). Some thalamic fibers 

 enter the cortex around the intraparietal sulcus. Note tliat no fibers deviate 

 toward the corpus callosum. (Compare with preceding and following figures.) 

 The auditory radiation (ar) as before enters the upper lip of the superior tem- 

 poral convolution (T,) which forms the floor of the Sylvian fossa. (FS). Optic 

 tract (77) is slightly injured; inferior parietal convolution (P7) ; postcentral 

 convolution (CP).
