The differential contributions of the parvocellular and the magnocellular subdivisions of the red nucleus to skilled reaching in the rat

Highlights • The rat red nucleus is a critical structure for the execution of aiming, arpeggio and supination. • The two subdivisions of the red nucleus play a differential role in skilled reaching. • The parvocellular division of the red nucleus abolishes supination.
