Sebastian Anthony, for ExtremeTech:
We know that a cluster of neurons firing can trigger the memory of your first kiss — but why? How can 100 (or 100,000) neurons, firing in a specific order, conjure up a beautifully detailed image of an elephant? We’ve already worked out how images are encoded by the optic nerve, so hopefully MIT isn’t too far away from finding out.
I think memory neurons are so compact because they’re just shorthand recipes that call upon our resident media library.
