WebDec 10, 1976 · Sensitization is an elementary form of nonassociative learning, related to behavioral arousal, in which a strong stimulus facilitates a reflex response. Studies of the neural circuit of the gill-withdrawal reflex in the isolated abdominal ganglion on Aplysia indicate that short-term sensitization is due to presynaptic facilitation. WebSummary • Learned non-use of a limb, which may be due to habituation, can be overcome by constraint-induced movement therapy, which forces the individual to use the limb. • Repeated exposure to stressful events may sensitize a person to stress, which can increase the likelihood of developing depression or anxiety disorders later in life. • Sensory … coarse boot
