Thought control: now with letters

Using ECoG (electrocorticography) and overlaying electrodes directly on the surface of the brain, scientists can record reactions when letters are flashed on a screen and then play back the letters when that thought pattern is brought up. It’s around 8 letters per minute, but it’s something.

There’s also a piece where they translate thought patterns into music. An interesting article.
