Olfactory receptors are the only receptors that make direct contact with brain interneurons, bypassing the afferent neurons that usually relay sensory information to the brain. This allows for rapid processing and perception of odor sensations. Taste receptors, photoreceptors, and mechanoreceptors all rely on afferent neurons to transmit information to the brain.
