Abstract

Face grooming sequences that involve coordination of the shoulders, tongue, and eyes develop remarkably normally in inbred mice with one or both forelimbs amputated from birth. This indicates endogenous control with a strong genetic component. Evidence for the maturational expression of "sensory expectations" was also obtained.
