abstract:The olfactory tubercle (OT, tuberculum olfactorium) is a multi-sensory processing center in the olfactory cortex that plays a role in reward behaviors. The OT is a composite structure that receives direct input from the olfactory bulb and contains the morphological and histochemical characteristics of the ventral pallidum and the striatum of the forebrain .
Theprojection from the nucleuslocus coeruleus (LC) to theolfactorytubercle (OT) has been studied with themethod of retrogradeaxonaltransport of HRP in 20rats.
