Sensitization is a non-associative learning process in which repeated administration of a stimulus results in the progressive amplification of a response.[1] Sensitization often is characterized by an enhancement of response to a whole class of stimuli in addition to the one that is repeated. For example, repetition of a painful stimulus may make one more responsive to a loud noise.
