and page 593), because the anatomical relationships mark them as of special 

 importance, and because we have such evidence also from physiological 

 experiments. 



As Stefani especially has pointed out, the symptoms following ablation of 

 the cerebellum present in many respects a striking agreement with those

 cortex of the frontal lobe. 1, Frontal cerebro-cortico-pontal path forming a medial bundle of 

 white fibers on the ventral side of the superior peduncle ; 2, bundle of fibers connecting the 

 temporal or temporal and occipital lobes with the cerebellum ; 3, cell body in the pons giving 

 off a fiber to terminate in the opposite cerebellar hemisphere ; 4, cell body connected with the 

 temporal cerebro-cortico-pontal path giving off a fiber to the opposite hemisphere of the 

 cerebellum; 5 and 6, Purkinje cells in the cerebellar cortex giving off fibers to the nuclei 

 pontis; 7 and 8, cell bodies in the nuclei pontis sending fibers toward the cerebrum.
