Adaptation to nitrogen narcosis manifested by timing behavior in the rat.

Abstract
Exposed 3 male NMRI-O albino rats trained on a temporal discrimination task to hyperbaric conditions. Initial exposures to a simulated depth of 200 ft in a hyperbaric chamber resulted in marked disruptions of the temporal discrimination and significant decrements in performance. Repeated exposures gradually lessened decrements until performance under pressure was equivalent to baseline control rates. (PsycINFO Database Record (c) 2006 APA, all rights reserved)
