Chapter 20 discusses the close interdependence of motor systems and other brain “systems.” Large areas in the parietal and frontal lobes are engaged in transformation of sensory information into action. Further, the purpose of movements is often not movement per se but to collect sensory information. Without precise control of the fingers, lips, tongue, and eyes, sensory information would be severely degraded. Movements are also crucial for body image and the feeling of ownership and agency. The close interaction between movements and cognition is witnessed by the high degree of sharing of nodes between networks serving motor control and cognitive tasks. Movements can be classified with regard to velocity and to whether they aim at stabilization or movement. Movements classifications also proceed from the most automatic (reflexes) to the least automatic (requiring maximal attention).
