Key findings

  • rTMS to the left inferior frontal gyrus slowed emotion recognition
  • It also eliminated mu-rhythm suppression
  • Control-site stimulation had no such effect

Repetitive TMS was used to briefly disrupt the left inferior frontal gyrus, a region thought to contain mirror neurons, or a control site at the top of the head. Disrupting the frontal region slowed emotion recognition and removed the usual suppression of the EEG mu rhythm, supporting a role for the mirror-neuron system in social perception.
