How Fast Can a Rat Smell?

Caption

Odor perception begins with an inhalation of odor molecules (odorants) to the olfactory receptor sheet within the nose. Increasing evidence is pointing towards the importance of sniffing behavior in olfactory coding. This image shows the respiratory trace (red) of a rat recorded during odor discriminations, overlaid on a main olfactory bulb calcium response map of the odorant eugenol.
