A genetic mutation causes mice to over-groom to the point of near baldness, except for an obsessively touched-up strip of hair between the ears. Such were the findings of an international team of neuroscientists at NYU Langone Medical Center, who intentionally bred the mice hoping to uncover clues about autism. Over-grooming, a repetitive motor behavior, has long been associated with autism in mice. But this experiment is the first in which a specific autistic motor behavior has been identified as the result of a process referred to in the science community as a biological pathway.
