Confidence and corrections: how we make and un-make up our minds.
Single neurons in several brain areas intervening between sensation and action signal the accumulation of sensory evidence favoring a particular behavioral response. Two new studies show that these same neurons encode decision confidence and that decision makers continue to process relevant sensory information even after a choice has been made.
