Worms Retain Memories After Decapitation

A worm's memories can survive even if you cut off its head. In a wild experiment,

scientists trained flatworms to hate red light. Then, they literally chopped

them in half. The tail section grew a completely new head and a brand-new brain.

Three weeks later, they tested them again. The worms with the new brains still

remembered to avoid the red light. Their memory wasn't just in the original brain; it was somehow

passed on to the new one. This suggests memories might be stored throughout their

entire nervous system, not just in one spot.
