title: Ethanol-induced grooming in mice selectively bred for differential sensitivity to ethanol.
abstract: In rats, excessive grooming follows the application of several forms of stress. The injection of alcohol may be considered as a stressor, since it increases plasma corticosterone levels. The present study examines the effects of ethanol injections on grooming in two lines of mice selected for differences in their hypnotic response to ethanol, i.e., the long sleep (LS) and short sleep (SS) lines developed at the Institute for Behavior Genetics at the University of Colorado at Boulder. Various subhypnotic doses of ethanol produced excessive grooming in the SS line, but this did not occur in the LS line. The SS mice also displayed more "novelty-induced" grooming compared to the LS mice after repeated exposure to the testing situation. The increase in excessive grooming in both the ethanol-induced and the novelty-induced excessive grooming situations was most apparent in the second half of the observation period.
