from the hypothalamus and thalamus and which dis- 

 charge fibers through the olfactory projection tract 

 of Cajal into the motor centers of the hypothalamus 

 and cerebral peduncle. They probably serve chiefly 

 higher correlations of smell, taste, and somesthetic 

 sensibility for feeding and visceral reflexes.

2. Medially there is the olfacto-striatum (part of 

 the caudate nucleus) which borders the lateral ven- 

 tricle for almost its entire length from far in front into 

 the temporal lobe. It receives fibers directly or in- 

 directly from the olfactory bulb and also fibers from 

 the somatic sensory centers of the thalamus. Its 

 eflFerent fibers go in part to the globus pallidus and 

 thence to the cerebral peduncle, and in part they go
