Summary

Story summary

A study from the University of Iowa shows a 20-minute exercise session boosts learning-related neural activity.
Researchers recorded brain activity in 14 epilepsy patients with intracranial EEG (iEEG) before and after exercise.
They observed increased high-frequency brain waves, or ripples, originating in the hippocampus and connecting to cortex.
This study provides the first direct evidence in humans that exercise alters brain rhythms tied to cognitive function.
