The term rhinencephalon denotes a composite substructure of the endbrain that is functionally identified with olfaction. Defined by connectivity, it includes the olfactory bulb and all structures that receive fibers from it, including the olfactory tract, the anterior olfactory nucleus, the olfactory tubercle, the medial olfactory stria, the lateral olfactory stria, parts of the amygdala and the piriform area ( Carpenter-1983 ). Other definitions, based on comparative neuroanatomy, such as rhinencephalon of Crosby, or on other criteria, such as Rhinencephalon (Nomina), are more extensive. For a concise review of the history and multiple uses of this term see Anthoney-1994.
