Olfactory bulb

A neural structure of the vertebrate forebrain involved in olfaction, the sense of smell.

Odours that circulate in the air are detected by neurons in the roof of the nose and these neurons stretch across the bony cribriform plate directly into the olfactory bulb of the brain. The olfactory bulb is one of the few places in the brain where new neurons appear over the course of the lifespan.
