NOSE HEATS UP WHEN YOU LIE: DNEWS NUGGET

Your nose might not grow each time you lie, but it does heat up. Researchers at the University of Granada used a thermal camera to image people as they told a lie. The scientists found that the area around the nose and in the orbital muscle in the inner corner of the eye tends heated up. They dubbed the phenomenon the «Pinocchio effect.»

In addition, a brain element called «insula» — which is a component of the brain reward system — activates. Concealing thoughts stimulates insula and makes a person’s face heat up. This information could be used by lie-detecting cameras to catch untruthful people.
