It turns out your brain might not be the only part of your body that remembers. Scientists at NYU have found that cells outside the brain—like those from your kidneys—can actually “learn” and form memories. By mimicking how the brain processes information using spaced repetition (as in studying with breaks), researchers showed that even non-brain cells can activate a key memory gene in response to patterns. This suggests memory isn’t just a brain thing—it might be a basic feature of many cells in the body.
