  • Abstract
  • Look Inside

When asked to perform movements, even simple ones, we often find them easier to do while observing another person's similar movements. We can imitate others without any effort. We have clarified the dynamics of the brain activation during observation and imitation of other act and still pictures that only imply motion by a whole-scalp type magnetoencephalography. During all conditions, the inferior frontal cortex (Broca region) was activated, and followed within 80-150 ms by activation in the primary motor cortex. Activation was always significantly stronger during action imitation than observation or execution.
