Nail-biting-like behavior in the Hprt−/0/Tg mice. The Hprt−/0/Tg exhibit distinct amphetamine-induced stereotypy that is reminiscent of nail-biting. The mice are in an unusual hunched posture and display head-bobbing behavior while simultaneously bringing their forepaws to their mouths and moving their mouths in a chewing or biting manner.
