Use Sleep to Enhance Learning, Memory & Emotional State | Dr. Gina Poe

About this video

Dr. Gina Poe, a professor at the University of California, Los Angeles, joins Huberman to discuss how specific phases of sleep shape learning, memory, emotional processing and growth hormone release. Dr. Poe explains that sleep can help consolidate procedural and emotional memories and can also discard the emotional tone of memories, acting in Huberman’s framing as a form of trauma therapy. A key point Huberman highlights is timing: Dr. Poe explains that going to sleep much later than your usual bedtime can mean missing the window for growth hormone release in the first hours of sleep, even if total sleep duration is adequate. The middle excerpt explores the locus coeruleus, the brain’s blue spot, its norepinephrine neurons, attention switching, and why its complete silence during REM sleep matters for clearing outdated synapses.
