The Need for Speed: Eye-Position Signal Dynamics in the Parietal Cortex

Accurate eye-position signals are critically important for localizing targets in space when the eyes move. In this issue of Neuron, Xu et al. (2012) provide evidence that eye-position gain fields in area LIP remain spatially inaccurate for some time after a saccade, indicating they are not updated rapidly enough to play a role in the computation of target locations for upcoming saccades.
