20-Minute Bike Ride Triggers Memory-Boosting Brain Ripples

A 20-minute session of light-to-moderate cycling rapidly increases hippocampal sharp wave-ripples and strengthens connectivity between memory-related brain regions, with higher exercise intensity yielding stronger ripple dynamics, providing the first direct human evidence that a single workout can modulate memory-related brain rhythms (observed in epilepsy patients and aligning with prior noninvasive imaging).
