Experiment study of the relation between motion complexity and event-related desynchronization/synchronization

To find a new method to get more classifiable EEG patterns in event-related desynchronization/synchronization based brain-computer interface, we designed a experiment to study the relation between finger motion complexity and the energy features of EEG. Data analysis show that around primary motor cortex, energy of finger motion under different complexity shows notable distinction in /spl beta/ band.
