Chemosensory pathways: from periphery to cortex.
The aim of this article is to summarise the anatomy of the chemosensory pathways. The vomeronasal organ, the olfactory system, the trigeminal system and the gustatory system will be reviewed in succession. For each of these systems, we will provide a description of the anatomy of the pathways sending the sensory message from the peripheral receptor to the cortical areas, passing through different relays in the nervous system. Particular emphasis will be paid to the anatomical features of the structures involved in chemosensory perception. This will help us to understand better how these systems interact and influence our social lives, our memories and our behaviour, and to evaluate patients with chemosensory dysfunction better.
