| Research Abstract |
The mirror neuron system is related to the understanding and imitation of action. To delineate the neural processes underlying the mirror neuron system, we examined the spatiotemporal distribution of neuromagnetic oscillatory changes during the observation of action with the intention to imitate.
Twelve subjects were instructed to observe a finger action and to imitate it later. We observed frequency dependent event-related desynchronizations (ERDs) in the temporal cortices, the left inferior parietal lobule (IPL), bilateral ventral premotor cortices (PMv), and the primary sensorimotor cortices (SM1). ERDs in the temporal and the premotor cortices peaked faster than those in the IPL and the SM1.
