Topic: anchored grid codes

Grid cells of the medial entorhinal cortex (MEC) have been proposed to play a key role in navigation. Competing models suggest they contribute to spatial localisation in general or have a dedicated role in path integration. Here, we aim to distinguish these possibilities by investigating how grid and non-grid cell firing varies as a function of performance in a virtual reality location memory task that can be solved either with a cued-based strategy or exclusively by path integration. We take advantage of spontaneous variation within and between recording sessions, which gives a complementary
