AbstractAnimals must navigate changing environments to find food, shelter or mates. In mammals, grid cells in the medial entorhinal cortex construct a neural spatial map of the external environment1,2,3,4,5. However, how grid cell firing patterns rapidly adapt to novel or changing environmental features on a timescale relevant to behaviour remains unknown. Here, by recording over 15,000 grid cells in mice navigating virtual environments, we tracked the real-time state of the grid cell network.

1 Introduction Metastable intermolecular composites (MICs) or nanothermites have recently been investigated for rapid energy and power generation in various domains, such as actuating microelectromechanical systems (MEMS), welding, joining, and propulsion.[1, 2] Typical MICs embody a reactive fuel – oxidizer formulation.
