In French Revolution-style, researchers decapitated flatworms—then did something that would give even Madam Defarge the creeps.

The scientists let the worms’ heads grow back and found that their memories returned along with the new noggins, according to a new study in the Journal of Experimental Biology.

Michael Levin and Tal Shomrat, biologists at Tufts University, have been studying how animals store and process information, whether it’s memories in the brain or the blueprint for developing organs in the body.

After the team verified that the worms had memorized where to find food, they chopped off the worms’ heads and let them regrow, which took two weeks.

Then the team showed the worms with the regrown heads where to find food, essentially a refresher course of their light training before decapitation.

Subsequent experiments showed that the worms remembered where the light spot was, that it was safe, and that food could be found there. The worms’ memories were just as accurate as those worms who had never lost their heads. (Test your memory with a National Geographic game.)
