The perception of an odour is a two-step process. First, there is a physiological process, i.e. the detection of chemical stimuli (odorous molecules) by olfactory receptors in the olfactory epithelium. Next, there is a neurologic process; olfactory neurons transduce receptors activation into neuronal electrical signals travelling along the olfactory nerve to olfactory bulb and finally, they are processed by higher cortical areas of the human brain where odour encoding and perception occur. Because of this, olfaction is a complex primal sense highly associated with attraction, mood, detection of danger and odours have the power to evoke distant memories and boost self-confidence. A lot of knowledge on olfaction has to be still get mainly regarding its relationship with other sensory stimuli as audio, visual, taste [1].
