Researchers at the University of York have a £1.1 million scanner to play with which can map the magnetic fields made by electrical activity in the brain. They tested 19 people to measure how the brain responded to expressions of emotion, both facial and vocal. They found a strong response from a part of the brain called the posterior superior temporal sulcus. This part of the brain responded to both facial and vocal stimuli although it was previously only thought to respond to facial cues.
