Fig. 42 In this is seen the common mass of small cells formed by the caudate 
and the nucleus of the lateral olfactory tract. Below it is a mass of neuropile 
in which appear a considerable number of larger cells belonging to the medial 
nucleus. The stria medullaris enters into this neuropile while the olfactory 
projection tract and stria terminalis in part are related to the small-celled nucleus 
(compare fig. 49). 
Fig. 43 Only a little of the small-celled mass is shown. The medial nucleus 
is larger and more dense and has shifted toward the medial wall. 
Fig. 44 The medial nucleus is still larger and surrounds the temporal horn 
of the ventricle, the rostral end of which is cut by the section. Immediately 
caudal to this the medial wall of the ventricle is occupied by hippocampal 
formation.
