Reading imagined words straight from the brain — when there's nothing to listen to

---

Normally, decoding brain signals requires lots of labeled examples of people thinking the same thought. These researchers found they could "borrow" the brain's response to hearing music to decode what happens when people merely imagine playing it — like using a dictionary in one language to decode a different one.

This means brain-computer interfaces for paralyzed patients could work with far fewer training sessions, because we can map the brain's imagination circuit using richer, easier-to-collect listening data.
