Smell intrigues both marketers and scientists because it has the unusual ability to call up powerful memories instantaneously. Smell is perceived by olfactory receptor cells, neurons with knob-shaped tips called dendrites that bind to molecular odorants. When an odorant stimulates a receptor, the cell sends an electrical impulse to the olfactory bulb, where odorant patterns are interpreted as different smells. Because the olfactory bulb is part of the limbic system, the emotional center of the brain, smell is closely connected to the amygdala and hippocampus, structures that influence our behavior, mood and memory.
