Classical conditioning of stress-induced analgesia.
Exposure of mice to a series of inescapable shocks produced analgesic reaction. This type of naloxone reversible, stress-induced analgesia responds to classical conditioning. Stress-induced analgesia involves activation of the opiate system: thus this type of analgesic mechanism responds to classical conditioning.
