The Neurobiological Mechanisms of Food Hoarding in Rodents

Quick fact

A squirrel's hippocampal neurons fire more strongly when it hoards food, helping it remember thousands of cache locations over long periods. This neural activity is so crucial that damaging the hippocampus can destroy a rodent's hoarding ability.

Why this is interesting

You've probably seen a squirrel bury a nut, but have you ever wondered why it can remember exactly where it buried it? The answer lies not just in the nut, but deep inside the rodent's brain.
