Olfactory trigone

Index Olfactory trigone

The olfactory trigone is a small triangular area in front of the anterior perforated substance. [1]

6 relations: Anterior perforated substance, Interpeduncular fossa, Olfaction, Olfactory sulcus, Olfactory tract, Rhinencephalon.

Anterior perforated substance

The anterior perforated substance is an irregularly quadrilateral area in front of the optic tract and behind the olfactory trigone, from which it is separated by the fissure prima; medially and in front, it is continuous with the subcallosal gyrus; it is bounded laterally by the lateral stria of the olfactory tract and is continued into the uncus.

Interpeduncular fossa

The interpeduncular fossa is a somewhat rhomboid-shaped area of the base of the brain, limited in front by the optic chiasma, behind by the antero-superior surface of the pons, antero-laterally by the converging optic tracts, and postero-laterally by the diverging cerebral peduncles.

Olfactory tract

The olfactory tract is a bundle of afferent nerve fibers from the mitral and tufted cells of the olfactory bulb that connects to several target regions in the brain, including the piriform cortex, amygdala, and entorhinal cortex.
