D While some scientists overlook the existence of a sixth sense for danger, a new research from Washington University in St. Louis has discovered a brain area that clearly acts as an early warning system and helps us adjust our behavior to avoid dangerous situations. Our brains are better at picking up not obvious warning signs than we previously thought, said Joshua Brown, a PhD in psychology in the issue of the journal Science. The findings offer exact scientific evidence for a new way to form a concept of the plex control processes taking place in and around the ACC, a brain area located near the top of the frontal lobes(耳垂 ) and along the walls that divide the left and right hemispheres(大腦半球 ). In the past, we found activity in the ACC when people had to make a difficult decision, or after they make a mistake, Brown said. But now we find that this brain area can actually learn to recognize when you might make a mistake, even before a difficult decision has to be made. So the ACC appears to act as an early warning system—— it learns to warn us in advance when our behavior might lead to a negative oute, so that we can be more careful and avoid making a mistake. By providing a clearer picture by which we self monitor and control our behavior, the study is an important step in efforts to develop more effective treatments for mental illnesses. It also provides a new way of understanding inappropriate behaviors that often acpany mental illnesses. Our results suggest how injury of the ACC can lead to breakdowns in the early warning system, so that the brain fails to stop or control inappropriate behavior ahead of time, said Brown. On the other hand, in those persons with mental disorder, the ACC might warn us of an uping problem even when no problem is in the existence.
