Left-right-alternating sweeps were extremely persistent, and were expressed continuously as rats ran in open arenas, on mazes, in completely novel envs and during REM sleep. This video shows decoding during a period of REM sleep (animal is completely immobile).

Excited to share that our paper is now published in Nature! In this study, we uncovered a grid-cell-based circuit in medial entorhinal cortex that probes the surrounding environment with theta-paced, sweeping spatial representations 🧵
