In other words: if you want to be the next Yves Saint Laurent, it helps to be completely and utterly obsessed with fashion. However, there are many aspects of the profession.

Olfactory receptor cells, actually neurons, are the site of transduction. Olfactory receptor cells are the only neurons in the nervous system that are regularly replaced (they last about 4-8 weeks). The size of the epithelium is a good indicator of the acuity of an animal's sense of smell.
The brain interprets the odorant patterns produced by activity in the different glomeruli as smell. There are 2,000 glomeruli in the olfactory bulb -- twice as many microregions as receptor cells -- allowing us to perceive a multitude of smells. An illustration of how receptors function in the olfactory system.
