Pain is a negative sensation that we want to get rid of as soon as possible. In order to protect our bodies, we react by withdrawing the hand from heat, for example. This action is usually understood as the consequence of the perception of pain. A team from the Technical University of Munich (TUM) has now shown that perception, the impulse to act and provision of energy to do so, take place in the brain simultaneously, and not, as was expected, one after the other.
