olfactory tubercle

ol·fac·to·ry tu·ber·cle

a small, oval area at the base of the cerebral hemisphere, between the diverging medial and lateral olfactory striae, in the anteromedial part of the anterior perforated substance; it is formed by a small area of allocortex characterized by the presence of the islands of Calleja. Corresponding to a much more prominent structure in nonprimate mammals (especially rodents and insectivores), the olfactory tubercle receives fibers from the olfactory bulb by way of the intermediate olfactory stria; it has efferent connections with the hypothalamus and the mediodorsal nucleus of the thalamus. Synonym(s): tuberculum olfactorium [TA]

olfactory bulb

Either of two paired, rod-shaped structures arising on the vertebral brain at the base of the frontal lobes, which are supported by the cribriform plate of the ethmoid bone. The cribriform plate’s perforations provide conduits for olfactory nerve processes.
