The authors performed patch-clamp recordings in the entorhinal cortex of mice navigating in a virtual-reality environment. They found that the membrane potential pattern of stellate cells during firing field crossings consists of a slow depolarization driving spike output, which is reproduced by a continuous attractor network model of grid cell firing; phase precession of spiking, however, is best explained by an oscillatory interference model.
