Whether the system can be flexibly redirected to prioritize specific locations has been unclear. Using large-scale #Neuropixels recordings in freely behaving rats, we find that both sweeps – and the internal direction signals driving them – are dynamically modulated moment by moment. (4/6)

Populations of grid cells and place cells encode a position signal that within a 125-ms theta cycle sweeps linearly outwards from the animal’s location into the ambient environment, alternating stereotypically between left and right directions. 🧹🧹🧹
