simultaneously. The frontal lobe holds new data in short term memory. Much of this information is filtered‚ dismissed and never stored. However‚ if this information is work second consideration‚ it is routed to and held in the hippocampus where if it is deemed important it is organized and indexed by the hippocampus and stored in the cortex. Our goal is to make information relevant enough to the student for it to be processed and stored in long term memory. Not only does physical movement give the brain
