Research Abstract

The present study investigated whether combining observation and imagery of an action increased brain excitability over the effects of either manipulation performed alone. Simultaneous observation and imagery of the action facilitated brain excitability as compared to that recorded during observation or imagery alone. It is expected that combining observation and imagery of an action could increase the effects of mental practice.
