Measurement of Mouse Squeals for 23 Hours as Evidence of Long-Term Effects of Alcohol on Aggression in Pairs of Mice

Abstract
A squeal-detection circuit was used to infer the effects of alcohol on aggressive behavior in pairs of mice over a period. Four conditions were compared, a no-injection control and injections of 30% alcohol, 10% alcohol, and a saline solution. Mouse squeals, the dependent variable, decreased with increases in alcohol dosage. The decrease in aggression-related squeals occurred during peak aggression periods up to 13 hr. after injection.
