Observing Body Movements Activates Related Brain Regions in Infants

Caption

Mean relative amplitude (dB) in the mu band (6𔃇 Hz) during observation of the experimenter (prior to her touching the object). Negative values reflect a reduction in mu rhythm amplitude (desynchronization) and positive values reflect an increase in amplitude (synchronization) relative to a pre-stimulus baseline. Desynchronization patterns significantly varied as a function of experimental group. There was greater reduction in amplitude over the hand areas (C3/C4) for infants who observed hand actions; conversely, there was greater reduction in amplitude over the foot area (Cz) for infants observing foot actions. Error bars represent 1 SEM.
