#1 Neuroscientist: After Listening to This, Your Brain Will Not Be the Same

Episode of The Mel Robbins Podcast · October 12, 2026 · 1 h 15 min

Mel Robbins talks with UBC neuroscientist Lara Boyd about neuroplasticity, how struggle, sleep, exercise and stress reduction rewire the brain, and how to make learning stick.

Summary

Mel Robbins interviewed neuroscientist Lara Boyd of the University of British Columbia about neuroplasticity, the brain's lifelong capacity to change. Boyd described leaving her career as a physical therapist after failing to help a young brain-injured patient walk, and argued that experience is the single largest driver of brain change, with engagement and motivation amplifying its effects. She explained that learning alters brain chemistry, structure and function, and that structural change requires time and sleep.

Boyd drew on her stroke research to describe a heightened 30-to-60-day window of plasticity after injury and a "sweet zone of difficulty" in which learners succeed roughly 50 to 60 percent of the time. She warned that disengagement causes the brain to change for the worse, describing plasticity as "use it or lose it," and said practice must get progressively harder to keep producing change.

She identified sleep, exercise and stress reduction as three key levers, calling exercise "rocket fuel" for the brain and describing lab studies pairing nine minutes of high-intensity interval training with practice, which improved overnight consolidation. She discussed cortisol's interference with growth factors, a study comparing yoga practitioners with runners, and an ongoing loving-kindness meditation study with teachers. Boyd also addressed first-person visualization, manifesting as brain priming, positive affirmations, gratitude, attention, and individual learning styles.

Robbins asked to be coached on learning conversational Spanish despite dyslexia, and Boyd recommended full auditory immersion, citing her daughter's French immersion experience. Boyd closed with her daily routine and UBC's motto "Tuum est" ("it is yours"), urging listeners to choose experiences wisely and "build the brain you want."

Chapters

  • Lara Boyd

    Boyd says that teaching schoolchildren that their brains change when they learn improves their grades.

    “if you take school children and you teach them their brain changes when they learn, their grades go up?”

    Listen from 3:37 · Educational neuroscience

  • Lara Boyd

    Boyd argues that experience, not any drug, is the single largest driver of change in the brain.

    “The single largest driver of change in our brain is our experience. There's no drug. There's no magic bullet”

    Lara Boyd

    Boyd states that a window of heightened brain excitability and plasticity after stroke lasts roughly 30 to 60 days.

    “this window of excitability after stroke, for example, seems to last 30 to 60 days, perhaps”

    Listen from 14:42 · Stroke rehabilitation

  • Lara Boyd

    Boyd reports that the most neuroplastic change occurs when stroke patients succeed at a task only about half the time.

    “when they're struggling, when their success rate is right around 50, 60%, so it's hard. this is when we're seeing the most neuroplastic change”

    Listen from 18:00 · Desirable difficulty in learning

  • Lara Boyd

    Boyd warns that disengagement also changes the brain, causing lost capacity in a use-it-or-lose-it manner.

    “if we do nothing or we do very little, then our brain will also change. And it won't be for the better. You will actually lose capacity”

    Listen from 25:30 · Neuroplasticity

  • Lara Boyd

    Boyd says the science of what happens during sleep is unsettled but it is clear that without sleep there is no learning.

    “I think that the jury is still out scientifically as to exactly what is happening in sleep. That is so essential. But certainly, we are very clear that if you don't sleep, you don't learn”

    Listen from 30:46 · Sleep and memory consolidation

  • Lara Boyd

    Boyd says sleep is where chemical changes become structural changes, so cramming does not produce real learning.

    “that is where that chemical change is being transformed into a structural change in the brain”

    Listen from 31:00 · Sleep and memory consolidation

  • Lara Boyd

    Boyd reports her lab found exercise paired with practice improved learning overnight, suggesting exercise aids memory consolidation.

    “the exercise group had significantly improved from where they were the night before. They got better overnight with exercise, paired with the practice the day before”

    Listen from 34:32 · High-intensity interval training

  • Lara Boyd

    Boyd describes a study in which yoga practitioners, unlike runners, engaged memory structures after amygdala activation in stressful situations.

    “in those runners, that amygdala lit up like a fireball. And I felt kind of silly because in our participants who practiced yoga”

    Listen from 37:51 · Meditation

  • Lara Boyd

    Boyd explains that cortisol competes with growth factors that enable plasticity, likening it to cars occupying limited parking spots.

    “cortisol has this negative effect of blocking the growth factors that allow the brain to be more neuroplastic. So they compete”

    Listen from 37:55 · Cortisol and stress

  • Lara Boyd

    Boyd rejects any magic number of practice hours and says practice must get progressively harder to keep changing the brain.

    “you can't just practice at the same difficulty over and over again, right? It needs to get harder as you go”

    Listen from 43:15 · Desirable difficulty in learning

  • Lara Boyd

    Boyd says first-person visualization produces more learning and brain change than observing oneself from outside.

    “if you're in your body, you're more first-person engagement, that mental rehearsal is going to have a better effect on learning and on brain change”

    Listen from 44:33 · Mental rehearsal and visualization

  • Lara Boyd

    Boyd suggests manifesting may work by triggering reinforcing dopamine release and priming the brain for change.

    “you may be getting these dopamine releases that are highly reinforcing towards that goal that you have, towards what you're working towards”

    Listen from 47:28 · Manifestation and goal setting

  • Mel Robbins

    Robbins describes believing she cannot learn languages despite years of French study and dyslexia.

    “I have a gigantic story that I am incapable of learning languages. I took seven years of French and cannot remember a damn word of it”

    Listen from 58:00 · Language immersion

  • Lara Boyd

    Boyd recommends that Robbins, as an auditory learner, learn Spanish through full immersion without English.

    “you need a Spanish immersion. So you need to just go. In fact, this is your excuse. You need to just go to Spain, pick a great city”

Today, you are getting a step-by-step guide on how to change your brain. Joining Mel is neuroscientist Dr. Lara Boyd, a professor at the University of British Columbia who directs the Brain Behaviour Lab there. This #1 neuroscientist will teach you how to rewire your brain at any age. There's a personal reason she's devoted her life to this work. Before becoming a neuroscientist, Dr. Boyd was a physical therapist. She spent three months unsuccessfully trying to help a man with a brain injury learn to walk again. Frustrated by how little she understood what was happening inside his brain, Dr. Boyd quit her job, got her PhD in neuroscience, and dedicated her career to figuring out how the brain learns and changes. Her message is incredibly hopeful: You are never too old, too late, or too set in your ways to change who you are and what you’re capable of. But becoming who you want to be doesn’t happen by accident. Dr. Boyd reveals what really reshapes your brain, what happens when you challenge yourself to do hard things, and how to make what you practice stick. In this episode, you’ll learn: -How to rewire your brain at any age -How doing challenging things can help your brain learn and change -The #1 driver of change in your brain -The daily habit that Dr. Boyd calls “rocket fuel” for your brain -How to prime your brain for success and the truth about manifestation -How to make lasting change, even if you’ve felt stuck for years Class is in session, because after you listen to this, your brain will not be the same.
