Summary

Coordination requires the movement to be represented very differently, in motor coordinates, before it can be carried out. The transformation from one coordinate system to another is computationally intensive and may make use of the cerebellum. The cerebellum is necessary for normal performance of both vergence movements and conjugate eye movements. The representation of eye and head movements in the cerebellum depends on whether the head movement is active or passive. The cerebellum can access them both by way of the interpositus/red nucleus pathway and by way of the fastigial/lateral vestibular nucleus pathway, as well as through the motor cortex. It takes into account joint interactions, force enslaving, motor strategies, and other important factors, to plan the movement. It uses internal models of our bodies to compensate for their physical characteristics. Finally, the cerebellum can correct movements rapidly using both internal models and sensory feedback.
