Effects of ethyl alcohol on hypothalamic affective defense in the cat

Hypothalamic stimulation was used to elicit affective defense in the cat. The behavior was recorded by direct observation and a video tape recorder, and different components thereof were evaluated on a rating scale. The effect of ethyl alcohol, 0.25, 0.5, 1.0 and 1.5 g/kg body weight, on behavior was studied. Doses of 0.25 and 0.5 g/kg had no clear effect; 1.0 and 1.5 g/kg depressed the majority of the rated components.
