Motor cortex activity during action observation predicts subsequent action imitation in human infants

From early on, human infants acquire novel actions through observation and imitation. Yet, the neural mechanisms that underlie infants’ action learning are not well understood. Here, we combine the assessment of infants’ neural processes during the observation of novel actions on objects (i.e. transitive actions) and their subsequent imitation of those actions. Most importantly, we found that the 7–10 ​Hz motor cortex activity increased during...
