Decoding the signals of speech

A slip of the tongue is really a slip of the brain.
Using high-resolution multi-electrode probes, researchers have deciphered the detailed signals our brains send to our throats and tongues. It turns out our brains can get a bit frazzled by having to activate similar muscles in quick succession – for example when we say tongue twisters.
This research could lead to the development of bionic brain implants that restore speech to stroke victims. Could an implant help with my fear of public speaking, I wonder…
This research appears in the 20 February 2013 issue of the journal Nature.
