Smell is our oldest sense. One of our earliest functions as simple organisms was to detect helpful or harmful molecules in our environment and then seek them out or avoid them. The brain's olfactory bulb still sits alongside regions processing emotion . As a result—although scientists aren't sure of the exact mechanism—dysfunctions of smell are closely associated with mood disorders.
