Al nostro cervello basta meno di un secondo per capire se la persona che abbiamo di fronte è un bugiardo. Lo rivela uno studio pubblicato sulla rivista scientifica Plos One dall'università di Milano-Bicocca ed effettuato in collaborazione con Centro nazionale di ricerca, università di Parma e università della California di San Diego.
I ricercatori hanno scoperto che la corteccia orbito-frontale ventromediale impiega 300 millisecondi per capire se l'espressione o l'atteggiamento fisico di una persona sono coerenti con lo stato d'animo che dovrebbe esprimere. L’esperimento è stato effettuato su 30 universitari. Gli studenti sono stati sottoposti a una tomografia elettromagnetica per misurare l'attività cerebrale mentre osservavano 280 fotografie nelle quali attori di teatro mimavano differenti stati d'animo.
