itgivesitthew: French neurologist Guillaume Duchenne, in the 19th century, occupied himself with applying small electric shocks to the faces of his patients, in order to understand the muscular movements behind expression (and to at the same time discover something of the ‘soul’). The genuine ‘Duchenne smile’ is named after him, since it was he who discovered that a true smile involves the involuntary movement of the muscles around the eyes.  Still, um … ouch.
