When a hunting dog picks up the scent of a deer, it sometimes freezes. On the spot. The same thing can happen to people who need to concentrate on a challenging task. Now researchers have made a discovery that adds to our knowledge of what happens in the brain when we suddenly stop moving. "We have found a group of nerve cells in the midbrain which, when stimulated, stop all movement. Not just walking; all forms of motor activity. They even make the mice stop breathing or breathe more slowly, and the heart rate slow down," explains Professor Ole Kiehn, who is co-author on the study.
