Power modulation of electroencephalogram mu and beta frequency depends on perceived level of observed actions.

ABSTRACT:

Introduction

The ability to understand actions and intentions of others is of great importance to social relationships and is associated with the mirror neuron system of the human brain. Whether conscious perception of specific actions is necessary to trigger activity in this system, or alternatively whether this response is independent of conscious perception is not known.

Methods

We addressed this issue by rendering videos of right hand movements invisible to conscious perception, and measuring electroencephalogram (EEG) power suppression in the mu (8-13 Hz) and beta (15-25 Hz) range as index corresponding to the magnitude of mirror neuron activity.

Results

In the beta range over bilateral sensorimotor sites, we find that suppression indices follow the reported perc
