Huberman Lab Clips(@HLPClips):Exercise does not grow new neurons: - Human data show little evidence for new neurons past puberty - The brain has a hard time folding entirely new elements into existing circuits, which is why some deaf people find cochlear implants intrusive - Exercise still benefits the brain, through hormonal signals like IGF-1 and the lactate pathway - Only about 10% of your total effort in a bout needs to reach the burn to send that benefit to your heart, liver and brain @hubermanlab
