Gender-specific response even in rats

As if to illustrate again what Women for Sobriety founder Jean Kirkpatrick preached decades ago about people, a recent study found different responses to alcohol in female v. male rats. A group of rats selectively bred to be heavy drinkers were exposed to changes in their lights-on v. lights-off schedule, like employees who work rotating shifts, to test the effect of this stress on their drinking. The male rats subjected to the shifting schedule decreased their alcohol intake; the female rats slightly increased theirs. Details.
