title: Noncommutativity of eye rotations and the half-angle rule.
abstract: In order to produce kinematically efficient behavior when dealing with the noncommutativity of rotations, the oculomotor system has developed strategies such as the half-angle rule. In this issue of Neuron, Ghasia and Angelaki demonstrate that during smooth pursuit eye movements the half-angle rule is implemented by the mechanical properties of the eye plant.
