Independent of a watch or the sun's position in the sky, humans somehow can figure out how much time has ticked by, and a new study reveals how. The study suggests the brain has no master clock, but instead that every individual brain circuit can learn to tell time.
"People think when you need to time something, that there's some clock circuit in the brain that we look to," said study co-author Geoffrey Ghose, a University of Minnesota neuroscientist. "What our study indicates is it's actually very different. For every little task or every little action or decision you make, you could potentially develop timing representations."
