Exercise may help the brain to build durable memories, through good times and bad.

Stress and adversity weaken the brain’s ability to learn and retain information, earlier research has found. But according to a remarkable new neurological study in mice, regular exercise can counteract those effects by bolstering communication between brain cells.

Memory has long been considered a biological enigma, a medley of mental ephemera that has some basis in material existence. Memories are coded into brain cells in the hippocampus, the brain’s memory center. If our memories were not written into those cells, they would not be available for later, long-term recall, and every brain would be like that of Dory, the memory-challenged fish in “Finding Nemo.”
