The effect of the inhalation of xylene on intracranial self-stimulation behavior was studied in rats in a flow-through (dynamic) inhalational behavioral chamber. Rats were exposed successively to four graded concentrations (102, 192, 419 and 623 ppm) of xylene vapor during 2-hr sessions on different days. The rate of lever-pressing showed a dose-dependent decrease during exposure to 192, 419 and 623 ppm of xylene. The 4-hr exposure to the smallest concentration (106 ppm) of xylene failed to show any effect on self-stimulation behavior. During a 5-day 2 hr/day exposure, the decrease in response observed on the 1st day was further accentuated with a nadir on the 3rd day; from the 4th day onwards, the depressant effect was attenuated showing the development of tolerance.
