Target Audience:
Intended for neuroradiologists and neuroradiology trainees with varying degrees of experience.

Learning Objective:
To understand more completely the development of the “peripheral” portion of the olfactory system.

Olfaction is the oldest of human senses. It is the only sense in which sensory neurons project outside the calvaria to detect sensory signals. It is the only sense that transmits information directly to the oldest portion of the human brain (the paleocortex) without any intervening thalamic relay. It is the single sense generated and supported by the largest family of genes. The olfactory system develops as a coordinated interaction between the ingrowth of olfactory sensory neurons from the olfactory epithelium of the nose and the outgrowth of the olfactory diverticulum from the frontal lobe. It is supported by continual, lifelong replenishment of the system by olfactory progenitor neurons of the nose and progenitor interneurons from the subventricular zone of the brain.
