title: [The determination of the nociceptive thresholds in freely moving rats].
abstract: A simple method for determination of nociceptive thresholds in free-moving rats is put forward. The method is based on the registration of vocalization reaction caused by the feed through the lungs connected with the stimulator by thin wires electrodes of gradually increasing impulses of constant electric current. The examples of effect of morphin and naloxone on the nociceptive thresholds as well the alteration of thresholds during predatory aggression are given.
