<P> The sensory neurons involved in smell are called olfactory receptor neurons . These receptor neurons contain receptors, called olfactory receptors, that are activated by the odor molecules in the air . The perception of these odor molecules is called a scent . </P> <P> Similarly to olfactory receptor neurons, taste receptors (gustatory receptors) in taste buds interact with chemicals in food to produce an action potential . </P> <P> Photoreceptor cells are capable of phototransduction, a process which converts light (electromagnetic radiation) into electrical signals . These signals are refined and controlled by the interactions with other types of neurons in the retina . </P> <P> The five basic classes of neurons within the retina are photoreceptor cells, bipolar cells, ganglion cells, horizontal cells, and amacrine cells . </P>
