THE OPTIC THALAMUS 57 



Plate XXVIII. shows the cells of the ventral nucleus of the thalamus. The nucleus is 

 bounded above by a distinct band of nerve fibres, entering the thalamus from the internal 

 capsule and sweeping inward toward the median nucleus. It is bounded on its outer and lower 

 surface by the fibres of the internal capsule. Hence it is more distinct as a separate nucleus 

 than any other of the thalamic masses. It is also distinguished from other nuclei by the size 

 and appearance of its cells, as already described. The cells of Luys' body, which lies not far 

 from this nucleus among the longitudinal bundles of the internal capsule, resemble these cells.
