[Aversive effects of halothane anesthesia in the rat, using extinction of tasks by positive reinforcement].
Immediate posttrial halothane anaesthesia accelerates the extinction of two previously acquired operant tasks--barpress learning or modified K-maze learning. This acceleration is not due to any motor impairment. These results are not consistent with the hypothesis of amnestic effects of halothane anaesthesia; they are interpreted in terms of aversive effects.
