Answer:
Sensitization.
Explanation:
Sensitization is a non-associative learning process that occurs after neurogenic inflammation when neurons become more responsive to both nociceptive and non-nociceptive stimuli, in which repeated administration of a stimulus results in the progressive amplification of a response. Sensitization often is characterized by increase in magnitude of response to a whole class of stimuli in addition to the one that is repeated, as well as expansion of receptive field, and emergence of spontaneous activity.
