Abstract
Coordination Dynamics posits that the stability of coordinated patterns of movement may be a key variable for organizing neural activity underlying coordinated action. In support, recent findings suggest that premotor areas play an important role in maintaining pattern stability. The present EEG study investigates how changes in neural activation (assessed via event-related power) are affected both by rate and stability of coordination. Nineteen participants coordinated finger taps with an auditory metronome in either a synchronized or syncopated pattern presented at five different rates (1.00, 1.25, 1.50, 1.75, and 2.00 Hz). Premotor areas demonstrated increases in event-related synchronization (neural deactivation) within the alpha band following slow, synchronized movements. Stepwise increases in rate led to greater desynchronization (neural activation) throughout the entire duration of the movement cycle. During syncopation medial premotor regions remained desynchronized during movement. Moreover, medial premotor was more involved during synchronization with subsequent increases in movement rate. Counter to previous findings, medial premotor did not modulate changes in coordination stability. We suggested that medial premotor regions are involved in processes related to the coincidence of the finger tap and auditory tone. These findings support premotor cortex's role in motor inhibition, timing, and execution.
