Brains update sensory predictions through single timing hub, electric fish study finds

In the split second after you hear a noise, your brain is already making a potentially life-or-death deduction: Did I do that, or did something else?

Our nervous systems answer this question using something called corollary discharge, a copy of a motor command that tells sensory areas what to expect from our own actions.
