"Acting is the least mysterious of all crafts," Marion Brando once said. But

for scientists, working out what is going on in an actor's head has always been something of a puzzle. Now, researchers have said actors show different patterns of brain activity depending on whether they are in character or not.

Dr Steven Brown, from McMaster University in Canada, said, "It looks like when you are acting, you are suppressing (压制) yourself; almost like the character is possessing you." Brown and colleagues report how 15 actors, mainly theatre students, were trained to take on a Shakespeare role — either Romeo or Juliet — in a theatre workshop. They were then invited into the laboratory, where their brains were scanned in a series of experiments. Once inside the MRI scanner, the actors were asked to answer a number of questions, such as: would they go to the party？ And would they tell their parents that they had fallen in love？ Each actor was asked to respond to different questions, based on two different premises (前提). In one, they were asked for their own perspective, while in the other, they were asked to respond as though they were either Romeo or Juliet.

The results revealed that the brain activity differed depending on the situation being tested. The team found that when the actors were in character, they use some third-person knowledge or inferences about their character. The team said they also found additional reduction in activity in two regions of the prefrontal cortex (前额皮质) linked to the sense of self, compared with when the actors were responding as themselves.

However, Philip Davis, a professor at the University of Liverpool, was unimpressed by the research, saying acting is about far more than "pretending" to be someone — it involves embodying (体现) the text and language.
