How Do Flatworms Keep Memories After Losing Their Heads?

This reel explores the astonishing ability of tiny planarian flatworms to regenerate entire new heads and brains while preserving learned behaviors. The narration details how researchers trained flatworms to expect food in a lit dish, then cut off their heads and watched as regrown worms remembered the task faster than untrained ones. The video ponders where memory might reside within these creatures—perhaps not just in the brain but throughout their bodies. It concludes by inviting viewers to share their thoughts on this scientific mystery.
