The Perfect Summary Podcast

Neuralink neurosurgeon Matt MacDougall explains brain implants for paralysis, robotic electrode surgery, animal research, and a sci-fi future for cognition.

Scott Kanoski explains how GLP-1, the vagus nerve, sugar and processed food shape hunger, cravings and hippocampal memory.

Stanford's Keith Humphreys on alcohol, cannabis, gambling, psychedelics and stimulants, and what the evidence says about recovery.

David Eagleman explains how the brain rewires itself, why time slows in a scare, why we dream, and how to bind your future self.

Read Montague explains dopamine as a learning signal, serotonin as its opponent, and what stress, SSRIs and screens do to both.

Andrew Huberman explains why heat limits effort and how cooling the palms, soles and face can multiply workout output and speed recovery.

Andrew Huberman explains how stress works, why short bursts help immunity, and real-time, medium and long-term tools to control it.

Andrew Huberman answers listener questions on light, exercise timing, learning during sleep and rest, smart drugs, temperature and food for better sleep and focus.

Andrew Huberman shows how to use your temperature minimum, light, exercise and food to beat jet lag, manage shift work and sleep better at any age.

Andrew Huberman explains how slow wave sleep builds motor skills and REM sleep strips emotion from memories, and how to get more of each.

Andrew Huberman explains how adults can change their brains through alertness, focused attention, visual focus tools and deep rest.

Andrew Huberman explains how infancy and puberty shape emotions and bonds, and offers a three-axis framework for understanding how you feel.

Andrew Huberman's toolkit for focus: 90-minute sessions, meal and caffeine timing, cold exposure, a 13-minute meditation and a few supplements.

Andrew Huberman explains how dopamine drives motivation, why pleasure comes paired with pain, and how intermittent reward keeps you on track.

Andrew Huberman on learning motor skills faster: many reps and errors, a quiet rest after practice, metronomes, a range-of-motion trick and visualization.

Andrew Huberman explains how to time cortisol and use short bursts of adrenaline to raise energy, strengthen immunity and learn faster.

Andrew Huberman explains how neurons drive fat loss and shares tools: fidgeting, shiver-based cold exposure, fasted training, caffeine, yerba mate and carnitine.

Psychiatrist and optogenetics pioneer Karl Deisseroth on diagnosing with words, light-controlled neurons, psychedelics, focus and his book Projections.

Andrew Huberman explains how skin and brain create pain and pleasure, and tools from cold exposure and hypnosis to supplements and reward timing.

Huberman explains the biology of major depression and reviews tools from EPA fish oil, exercise and creatine to ketamine, psilocybin and ketogenic diets.

Andrew Huberman explains hunger and satiety circuits, why morning protein matters, and the brain science and treatments behind anorexia, bulimia and binge eating.

Andrew Huberman explains the biology of ADHD and focus, from dopamine and brain networks to diet, supplements, drugs, blinking and smartphone limits.

Huberman explains how dopamine peaks lower your baseline, and how cold water, intermittent rewards and loving effort keep motivation high.

Johns Hopkins researcher Dr. Matthew Johnson explains how psilocybin, MDMA and other psychedelics are studied as treatments, and what the real risks are.

Circadian scientist Samer Hattar explains how to time light, meals and exercise, his tripartite model, jet lag fixes and why daylight saving time hurts.

Andrew Huberman explains how the brain and immune system talk to each other, with tools from nasal breathing to cyclic hyperventilation and sauna.

Huberman explains why gratitude lists fall short and builds a brief, story-based gratitude practice grounded in neuroscience and immune research.

UCLA's Jack Feldman explains how the brain controls breathing, why we sigh, how breathing shapes emotion and cognition, and simple breathwork to try.

Huberman explains the neuroscience of habits and offers a phase-based daily plan, a 21-day system, and a simple method for breaking bad habits.

Andrew Huberman explains why low-stakes play is a powerful portal to neuroplasticity for children and adults, and how to add an hour of play a week.
