Cut a planarian worm's head off. It grows a new brain. The new brain remembers things the old brain learned.
Nobody can fully explain this. The standard model says memory lives in synaptic connections, but the new neurons have never fired before. Something else is carrying the information. Maybe bioelectric patterns, maybe the extracellular matrix, maybe something we haven't named yet.
We've been studying memory for decades and we still don't actually know where it lives.
