Research at the Donders Institute for Brain, Cognition and Behaviour, based in the Netherlands, appears to show that intensive physical exercise timed around four hours following learning can be beneficial for improving the ability to remember information subsequently (in healthy persons). Chemicals produced in the body during physical exercise, such as dopamine and norepinephrine, are thought to have a role in improving memory formation.
