olfactory transduction

the sequence of events by which the chemical molecules of an odorant are detected by olfactory receptors and transformed by the olfactory nerve into electrical signals perceived as smells by the olfactory bulb. As in other sense systems, the conjoint activation of many receptors and the modulating effects of second messengers play important roles in olfactory transduction.
