Olfactory Pathway Gustation Pathway Auditory Pathway 1. Olfactory receptors are neurons  that respond to chemicals  associated with specific odors 2. Olfactory neurons possess fine  hair-like projections called cilia,  which have receptor sites that  bind with specific chemicals. 3. Binding of airborne chemicals to  a receptor site produces a  graded excitatory postsynaptic  potential called a receptor  potential. 4. If threshold is reached, an action  potential is initiated which  causes neurotransmitter release  signaling the brain an odor is  present.  1. Taste receptors lack axons and  dendrites but possess microvilli  that project in the mouth where  they encounter chemicals that  act as taste stimuli 2. Taste stimuli open sodium  channels or close potassium  channels depolarizing the  receptor cell. 3.
