How do we detect the smell of an agarbatti (incense stick)?

Answer :

The temporal lobes of the brain are concerned with smell, hearing and taste. When an incense stick burns, it produces fumes of pleasant smells. The forebrain has regions that receive impulses from various receptor organs. So when the smell of aggarbatti reaches our olfactory receptors (in nose), the receptors send electrical or chemical impulses via neurons to the forebrain. The forebrain thus detects the smell of an aggarbatti.
