Abstract
The phenomenon of behavioral augmentation of tolerance (BAT) to ethanol (EtOH) in the rat was replicated in studies using the moving belt test of intoxication. Rats performing the test daily under the influence of EtOH (2.2 or 2.5 g/kg i.p.) developed tolerance more rapidly than those receiving the same dose after each daily session on the belt. However, both groups reached the same maximum level of tolerance. Acceleration of tolerance by BAT was proportional to the frequency of performance under the influence of EtOH when total exposure to EtOH was held constant. The degree of tolerance produced by BAT could not be increased by daily gavage with a large dose (6 g/kg) of EtOH. After termination of EtOH administration, tolerance produced by BAT was lost at the same rate, whether or not daily alcohol-free sessions on the belt test were given. These findings are consistent with the hypothesis that BAT and conventionally produced tolerance differ only in rate.This publication has 7 references indexed in Scilit:
