title: Progress in understanding spatial coordinate systems in the primate brain.
abstract: A new study in this issue of Neuron shows that when monkeys reach to a visual target, neurons in the dorsal premotor cortex compare the location of the target, the hand, and the point of visual fixation. The neurons therefore encode space through a combination of eye-centered and hand-centered coordinates.
