The brain clock that keeps memories ticking

Just as members of an orchestra need a conductor to stay on tempo, neurons in the brain need well-timed waves of activity to organize memories across time. In the hippocampus–the brain’s memory center–temporal ordering of the neural code is important for building a mental map of where you’ve been, where you are, and where you are going. New research has pinpointed how the neurons that represent space in mice stay in time.
