Rats Self-Administer Nonrewarding Brain Stimulation to Ameliorate Aversion

Hypothalamic stimulation in rats both reduces escape from noxious hindbrain stimulation and sustains self-administration only when hindbrain stimulation is inescapable. Self-administration reflects an aversion-ameliorative action of brain stimulation and not a positive reinforcement process. The psy...

Zusammenfassung:Hypothalamic stimulation in rats both reduces escape from noxious hindbrain stimulation and sustains self-administration only when hindbrain stimulation is inescapable. Self-administration reflects an aversion-ameliorative action of brain stimulation and not a positive reinforcement process. The psychophysical testing used is offered as a model for establishing the analgesic properties of brain stimulation.
