How to Change Your Brain & Increase Neuroplasticity at Any Age | Dr. Andrew Huberman

Adult neuroplasticity requires active engagement through alertness and focus, moving beyond the passive learning capabilities of childhood. The process relies on the release of acetylcholine from the nucleus basalis, which acts as a gatekeeper for neural remapping. While pharmacological interventions can influence this pathway, they often carry significant health risks and addictive potential. Instead, moderate-intensity exercise serves as a safe, effective trigger for the vagus nerve, stimulating the release of norepinephrine and acetylcholine to open a window for enhanced learning. This physiological state, combined with incremental practice and consistent, high-quality sleep, enables the brain to rewire circuits and acquire new skills throughout adulthood. By strategically timing cognitive efforts in the hours following exercise, individuals can optimize their capacity for self-directed, adaptive neural change.
