Olfactory trigone

Olfactory Trigone

The Olfactory Trigone is a small triangular area in the anterior part of the rhinencephalon. It is located on the ventral surface of the brain, anterior to the anterior perforated substance.

Anatomy

The Olfactory Trigone is bordered anteriorly by the olfactory tract, posteriorly by the anterior perforated substance, and laterally by the medial olfactory stria and lateral olfactory stria. The area between the medial and lateral olfactory stria is often referred to as the olfactory area.

Function

The Olfactory Trigone is part of the olfactory system, which is responsible for the sense of smell. It serves as a relay station for olfactory signals before they are sent to the olfactory cortex in the brain.

Clinical Significance

Damage to the Olfactory Trigone can result in a loss of smell, a condition known as anosmia. This can be caused by a variety of factors, including head trauma, infections, and neurodegenerative diseases such as Alzheimer's disease and Parkinson's disease.
