A small change in receptors in the brain of mice seem to make new born mice not worry or fret if they are removed from their mother. This discovery has possible implications to explaining aspects of autism and attachment disorders. Researchers Francesca R. D'Amato of Italy and Brigitte Kieffer of France bred mice that had a receptor called µ-opioid receptor knocked out. They discovered that these mice did not make their usual calls to their mothers even when they had been with their mother. These receptors are an important part of the brain that provide a sense of comfort and attachment. This research suggests a possible reason for some autistic behaviours and a more recently diagnosed condition called reactive attachment disorder. |
