A developmental approach of imitation to study the emergence of mirror neurons in a sensory-motor controller

Mirror neurons have often been considered as the explanation of how primates can imitate. In this paper, we show that a simple neural network architecture that learns visuo-motor associations can be enough to let low level imitation emerge without a priori mirror neurons. Adding sequence learning mechanisms and action inhibition allows to perform deferred imitation of gestures demonstrated visually or by body manipulation. With the building of a cognitive map giving the capability of learning plans, we can study in our model the emergence of both low level and high level resonances highlighted by Rizzolatti et al
