#116 - 40 Hz Brain Stimulation

Matt ventures into the realm of 40 Hz "gamma" rhythms - the conductor of the biological orchestra during high-order cognition - to explore how non-invasive light and sound stimulation can entrain brain activity, nudging neurons into synchrony. Crucially, Matt examines ground-breaking Alzheimer’s research where this rhythm rallies the brain's immune cells to clear toxic plaques, potentially stabilizing memory and preventing atrophy in early-stage patients.

Beyond cognition, Matt uncovers a neurobiological paradox: high-frequency stimulation can actually induce sleepiness by triggering a surge in adenosine. He discusses findings suggesting 40 Hz therapy acts as a "paradoxical lullaby," improving insomnia and regulating mood via the prefrontal cortex. While remaining grounded in scientific skepticism, Matt considers if this non-pharmacological intervention could become a vital addition to our future health toolkit.
