Mice were injected with 20% ethanol in 0.9% NaCl, or with 0.9% NaCl without ethanol during sessions of behavioral thermoregulation in a tubular temperature gradient (ambient temperature range approximately 9-38°C). Internal temperature was monitored with an implanted telemetry device. An imaging system recorded the position (selected temperature) of the mouse within the gradient every 5 sec. A dose of either 2.25 or 2.60 g ethanol/kg body wt. produced significantly lower body temperatures than control (NaCl) injections. The 2.60 g/kg dose produced significantly lower selectec temperatures than either the NaCl or 2.25 g/kg injections. Doses of 2.75 g ethanol/kg and above incapacitated the mice, precluding accurate behavioral thermoregulation. Utilizing a thermoregulatory index following experimental and control injections indicated that 2.25 or 2.60 g ethanol/kg leads to a decrease in the regulated temperature of mice.
