The mouse moves through the virtual world of a video game with the help of a Styrofoam ball that floats on compressed air.THOMAS HAINMÜLLER, MARLENE BARTOS Researchers looked into the brains of live mice experiencing a virtual environment to see how neurons were altered through the process of memory consolidation, according to research published June 6 in Nature.  

A look into memory: A video recording shows neurons begin to flash as soon as they are activated.THOMAS HAINMÜLLER, MARLENE BARTOS 

“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.
