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 neu...
