Fields of gain in the brain.
For more than two decades, neuroscientists have debated the role of "gain fields" in sensorimotor transformations. In this issue of Neuron, Chang et al. demonstrate a tight correlation between eye and hand position gain fields in the "parietal reach region," strongly suggesting that they play a functional role in computing the reach command.
