文摘

The study represents the first ERPs investigation of the temporal coupling effect for bimanual reaching movements. Behavioral data confirmed the temporal coupling betweeen hands. No difference between hands was found in the ERP related to the movement preparation showing that bimanual actions are prepared as single movements. During execution, movements towards smaller and further targets produce stronger activity (MP and N4 components). The right hand shows a leading role in the movement and it induces a stronger activity regardless of the distance and size of the target.
