This chapter talks about two kinds of internal models of limbs: dynamic models and kinematic models. Dynamic models predict the time course of the movement. In order to do this, dynamic models must take into account properties like inertia, friction, and elasticity of the components of the arm. Dynamic models are thought to be calibrated using sensory feedback from the limb itself, but kinematic models can use any sensory information, and are useful for prey capture, for example. Kinematic models represent the desired change in position in Cartesian coordinates. Skilled movements of the fingers, like accurate throwing, require some practice to execute well. Playing a musical instrument, for example, almost certainly requires cerebellar motor learning. Locomotion is one of the most difficult motor skills to quantify. The posterior lobe of the cerebellar cortex appears to be important for memory encoding for several kinds of skill learning involving the limbs.
