Sixth sense

The results (…) may help explain the apparent “sixth sense” we have for danger. This is the first time that specific regions of the brain have been identified to be involved in the phenomenon. The human brain is able to detect social threats in these regions in a fast, automatic fashion, within just 200 milliseconds. (…) Even more surprising for the scientists was the discovery that anxious individuals detect threat in a different region of the brain from people who are more laid-back. It was previously thought that anxiety could lead to oversensitivity to threat signals. However, the new study shows that the difference has a useful purpose. Anxious people process threats using regions of the brain responsible for action. Meanwhile, ‘low anxious’ people process them in sensory circuits, responsible for face recognition.
