Overview
- Researchers used intracranial EEG to record neural activity before and after 20 minutes of stationary cycling.
- Exercise increased the rate of hippocampal sharp wave–ripples and propagated signals to cortical regions involved in learning and recall.
- Coupling and phase synchrony strengthened between hippocampal ripples and ripples in limbic and default mode cortical networks.
- Higher heart rate during the workout correlated with larger post-exercise ripple increases.
- The peer-reviewed study was published March 9 in Brain Communications, aligns with fMRI patterns reported in healthy adults, and the team plans follow-up work pairing direct recordings with memory tests.
