We remember things longer if we take breaks during learning, referred to as the spacing effect. Scientists gained deeper insight into the neuronal basis for this phenomenon in mice. With longer intervals between learning repetitions, mice reuse more of the same neurons as before — instead of activating different ones. Possibly, this allows the neuronal connections to strengthen with each learning event, such that knowledge is stored for a longer time.
Remember more by taking breaks: Longer breaks during learning lead to more stable activation patterns in the brain. — ScienceDaily
