Summary

This chapter makes use of eye-movement systems to illustrate how cerebellar motor learning can provide fine adjustments, increasing or decreasing the speed and amplitude of movements to make them more accurate. The best-studied eye-movement system, with regard to learning, is the vestibulo-ocular reflex (VOR). The VOR is such a simple system that it is not terribly interesting in itself (except, of course, to its dedicated fans). But there is a payoff for understanding the VOR: building on what we learn from this simple system, we can move on to understand other, more complex forms of motor control and motor learning. Plasticity at the glomeruli and plasticity in themolecular layer may interact synergistically to adjust the response amplitudes for P-cells with various on-directions. The presence of linear filters in the VOR might be a fundamental difference between the cerebellar modules that control the NMR and the VOR.
