"Opposing Brain Waves: The Key to Memorization and Recall"

US researchers have discovered that brain waves move in opposite directions depending on the type of cognitive task being performed, with learning processes flowing one way and recall actions bouncing back the other direction. This finding sheds light on how the brain supports various behaviors and may have implications for conditions like memory loss. The study, published in Nature Human Behavior, utilized electrodes implanted on the cerebral cortex of epilepsy patients to directly observe brain wave activity during different cognitive tasks, providing valuable insights into the brain's dynamic functioning.
