Title: [abstract] PARAMETERS OF BEHAVIORAL ADAPTATION TO NITROGEN NARCOSIS.
Author: Walsh, JM
Abstract: Behavioral adaptation to the effects of nitrogen narcosis has been recently quantified , and sugges tions have been made that the mechanics of this adaptation are similar to drug tolerance. Rats trained by operant conditioning techniques on a multiple schedule of reinforcement were repeatedly exposed at various intervals to a simulated depth of 275 ft (in a hyperbaric chamber) to determine the parameters of adaptation to nitrogen narcosis. Marked decrements in schedule performance occurred when air was breathed at 275 ft. Repeated exposures to pressure gradually resulted in the development of behavioral adaptation, but during this process behavioral disruptions affected schedules differentially. The frequency of exposures was shown to be an important factor in the adaptation process; dive intervals of 2-3 days were found to be optimal for the acquisition and maintenance of behavioral tolerance. However, the maximum depth where tolerance could be developed was dependent on individual thresholds, which were not affected by either the number or frequency of exposures. Once acquired, behavioral tolerance to the effects of pressure was maintained for several weeks.
