A Biologically Inspired Visuo-Motor Control Model based on a Deflationary

We propose now an alternative visual–motor control model for goal-oriented actions, which is centred on the following interpretation of mirror neurons: – Mirror neurons code an expected perception; – Mirror neurons compare the expected perception representation with the actual perception. As we will ...
