Dramatic decreases in brain reward function during nicotine withdrawal
Article Abstract:
Research into whether the nicotine abstinence syndrome, which has similarities with withdrawal from other addictive drugs, is also characterized by declines in brain reward function has established that spontaneous nicotine withdrawal in rats leads to a substantial reduction in brain reward function. It is suggested that elevations in intercranial self-stimulation reward thresholds seen in rats during nicotine abstinence could be a valuable model of the affective elements of nicotine withdrawal in humans.
