Olfactory trigone
Trigonum olfactorium
Definition
The olfactory trigone exists in humans and refers to the triangular space at the angle of separation between the medial and lateral olfactory tracts. In macrosmatic animals such as domestic mammals, this structure is not considered anatomically distinct: the space between the two tracts is much larger, and the gray matter occupying it forms a broad, rounded prominence called the olfactory tubercle.
