Scientists can livestream how the mouse brain’s hippocampus maps the physical world and accesses those memories.

“As the mouse is getting to know its environment, we use a special microscope to look from the outside into its brain and we record the activities of its nerve cells on video,” Thomas Hainmüller, a coauthor on the study, says in a statement. He and his colleague found that the mouse’s location within the game would trigger specific neurons among a group of cells that was engineered to light up when activated. The resulting neural map reflected memories of different areas within the virtual environment.
