Does the thought of aging, brain injury, or a learning disability scare you because you believe your brain is permanently fixed?
If you’ve ever been told you’re “not a math person,” that you’re “too old to learn a new language,” or that your brain is simply “wired that way”, The Brain That Changes Itself might just change your life.
Overview
The Brain That Changes Itself by Norman Doidge, M.D., is a groundbreaking work that challenges the centuries-old belief that the adult brain is fixed and unchangeable.
Through compelling case studies and interviews with pioneering scientists, whom Doidge calls “neuroplasticians”, the book demonstrates that our brains are remarkably adaptable, capable of rewiring themselves in response to injury, learning, and even thought alone.
Published in 2007 by Viking Press, the book became a New York Times bestseller. The New York Times called it “mind-bending, miracle-making, reality-busting stuff”.
Jeanette Winterson described it in The Guardian as “an utterly wonderful book, without question one of the most important books about the brain you will ever read”.
What makes this book different from typical neuroscience writing is its deeply human approach. Doidge doesn’t just present dry scientific data, he tells stories. Stories of a woman who felt like she was perpetually falling until a device on her tongue rewired her brain.
Stories of stroke victims who learned to move again decades after doctors gave up on them. Stories of a woman born with only half a brain who functions, and thrives, in the world.

Table of Contents
Background
To understand why this book matters, you need to understand what came before. For four hundred years, mainstream medicine and science believed that brain anatomy was fixed. The common wisdom was that after childhood, the brain changed only when it began the long process of decline. Brain cells that failed to develop properly, or were injured, or died, could not be replaced.
This view had three major sources:
- The fact that brain-damaged patients could so rarely make full recoveries
- Our inability to observe the living brain’s microscopic activities
- The idea, dating back to the beginnings of modern science, that the brain is like a glorious machine
The machine metaphor led to the concept of “hardwiring”, the idea that the brain is like computer hardware with permanently connected circuits, each designed to perform a specific, unchangeable function. If a circuit was broken, it was broken forever.
This “neurological nihilism” spread through our culture, stunting our overall view of human nature. Since the brain could not change, human nature—which emerges from it—seemed necessarily fixed and unalterable as well.
The Brain That Changes Itself Summary: What I Learned
Let me share what I took away from this book—chapter by chapter, insight by insight. By the time you finish reading this summary, you’ll have a solid understanding of neuroplasticity and its implications.
Chapter 1: A Woman Perpetually Falling
The book opens with Cheryl Schiltz, a woman who lost her vestibular (balance) system after being given the antibiotic gentamicin following a routine hysterectomy. Excessive use of gentamicin is known to poison the inner ear structures, and Cheryl was given the drug way beyond the limit.
She became one of a small tribe of gentamicin’s casualties, known among themselves as “Wobblers.” She felt like she was perpetually falling, even when she was on the ground. “An imaginary trapdoor opens up and swallows me,” she told Doidge.
Enter Paul Bach-y-Rita, one of the great pioneers of neuroplasticity. He created a device, a construction hat with an accelerometer and a plastic strip with electrodes that went on the tongue, that replaced Cheryl’s damaged vestibular system. The device sent balance signals to her brain through her tongue. After using it, Cheryl could stand, dance, and even jump rope.
But here’s the truly remarkable part: after repeated sessions, the effects lasted longer and longer. Eventually, after a year of using the device, Cheryl no longer needed it at all. Her brain had rewired itself. As Doidge writes: “We are awakening some kind of force inside her”.
This chapter introduces Doidge’s central thesis: we see with our brains, not with our eyes. Bach-y-Rita famously said, “When a blind man uses a cane, he sweeps it back and forth… what he subjectively perceives is not the cane’s pressure on his hand but the layout of the room”.
Chapter 2: Building Herself a Better Brain
This chapter tells the story of Barbara Arrowsmith Young, a woman born with severe learning disabilities. She had areas of brilliance—her auditory and visual memory both tested in the 99th percentile, but these coexisted with areas of retardation. She couldn’t understand grammar, couldn’t read a clock, couldn’t tell her left from her right.
Barbara discovered the work of Aleksandr Luria, a Russian neuropsychologist who studied soldiers with brain injuries. She realized that her deficits had an address in the brain. Then she read about Mark Rosenzweig’s experiments showing that rats raised in stimulating environments developed heavier, more complex brains.
Lightning struck. If the brain could be modified, maybe she could fix her own deficits.
She designed mental exercises for herself—reading hundreds of cards with clock faces, trying to tell the time, checking the answers. After exhausting weeks, she could read clocks faster than normal people. More importantly, her other difficulties, with grammar, math, and logic, began to improve. For the first time in her life, she began to live in real time.
She went on to found the Arrowsmith School, where children with learning disabilities do brain exercises to strengthen their weak functions. The school has helped countless children who were told they would never improve.
Chapter 3: Redesigning the Brain
This chapter focuses on Michael Merzenich, whom the Irish neuroscientist Ian Robertson has described as “the world’s leading researcher on brain plasticity”.
Merzenich’s work fundamentally changed how we understand brain maps. He showed that brain maps are not fixed—they change depending on what we do. In one experiment, he amputated a monkey’s middle finger and found that the brain map for that finger disappeared, while the maps for the adjacent fingers grew into the space.
This demonstrated a principle Merzenich called competitive plasticity—there’s an endless war of nerves going on inside our brains. If we stop exercising our mental skills, we don’t just forget them; the brain map space for those skills is turned over to the skills we practice instead.
Merzenich also discovered that paying close attention is essential for lasting plastic change. When animals performed tasks automatically, without paying attention, the changes didn’t last.
This research led to the development of Fast ForWord, a computer program that helps children with language disabilities rewire their brains.
The program exercises basic brain functions involved in language, from decoding sounds up to comprehension. Studies showed that children who did Fast ForWord made significant progress on standardized language tests, with many moving ahead 1.8 years of language development in just six weeks.
Chapter 4: Acquiring Tastes and Loves
This is perhaps the most controversial chapter in the book. Doidge applies neuroplasticity to sexuality and love—arguing that our sexual tastes are not fixed but acquired, often during critical periods in childhood.
He describes patients who became addicted to Internet pornography and developed tolerance, needing more and more extreme content to get aroused. As one of his patients put it, he had “built up a tolerance to magazines” and needed videos.
Doidge writes: “The content of pornography is a dynamic phenomenon that perfectly illustrates the progress of an acquired taste”. He argues that pornography satisfies every prerequisite for neuroplastic change—focused attention, repetition, and dopamine release.
He also explores the neuroscience of romantic love, citing studies showing that when lovers look at photos of their sweethearts, their brains look like those of people on cocaine. Dopamine, the reward neurotransmitter, is activated.
Chapter 5: Midnight Resurrections
This chapter describes the work of Edward Taub, whose constraint-induced movement therapy has helped countless stroke victims recover movement years after their strokes.
Taub discovered the concept of learned nonuse. When monkeys lost sensation in one arm, they stopped using it—not because they couldn’t, but because they had learned not to. By restraining the good arm, Taub forced the monkeys to use the affected one, and they recovered.
He applied this insight to stroke patients.
By immobilizing the good arm and forcing patients to use their paralyzed arm for six hours a day, ten to fifteen days straight, many recovered significant function. One patient, a lawyer who had his stroke at age seven—forty-five years before—was able to improve significantly.
Brain scans confirmed that the therapy actually increased the size of the brain maps governing the affected limbs.
Chapter 6: Brain Lock Unlocked
Jeffrey Schwartz, a UCLA psychiatrist, developed a neuroplastic treatment for obsessive-compulsive disorder (OCD). Brain scans show that OCD involves three brain areas that get “locked” together: the orbital frontal cortex (which detects mistakes), the cingulate gyrus (which triggers anxiety), and the caudate nucleus (which normally allows thoughts to flow from one to the next).
Schwartz’s treatment involves two key steps:
- Relabeling: recognizing that the intrusive thought is not a real threat but an OCD symptom
- Refocusing: shifting attention to a positive, pleasurable activity
This refocusing “grows” a new brain circuit that can compete with the obsessive one. According to use-it-or-lose-it, the pathological networks will weaken.
Schwartz found that 80% of his patients improved with this method, often in combination with medication. Brain scans confirmed that the three locked brain areas began to fire separately.
Chapter 7: Pain: The Dark Side of Plasticity
V. S. Ramachandran, one of the most colorful scientists in the book, solved the centuries-old mystery of phantom limbs. Amputees often feel excruciating pain in limbs that no longer exist.
Ramachandran discovered that when a limb is amputated, the brain map for that limb doesn’t just disappear, it gets invaded by neighboring maps. In one patient, touching the face caused sensations in the phantom hand.
Ramachandran invented a simple but brilliant solution: a mirror box. By placing a mirror in a box and having the patient move their good hand while looking at its reflection, the patient’s brain was fooled into thinking the phantom limb was moving.
This relieved pain and, in some cases, eliminated the phantom entirely.
Chapter 8: Imagination: How Thinking Makes It So
Alvaro Pascual-Leone, a neuroscientist at Harvard, showed that we can change our brain anatomy simply by using our imaginations.
In one experiment, he taught two groups of people to play a piano sequence. One group practiced physically for two hours a day. The other group only imagined practicing. By the end of five days, both groups showed similar brain map changes, and the imagining players were as accurate as the physical players were on their third day.
As Doidge writes: “Everything your ‘immaterial’ mind imagines leaves material traces. Each thought alters the physical state of your brain synapses at a microscopic level”.
Chapter 9: Turning Our Ghosts into Ancestors
This chapter argues that psychoanalysis is actually a neuroplastic therapy. Doidge presents the case of Mr. L., a man in his late fifties who had been depressed for over forty years.
Mr. L. had lost his mother at twenty-six months old and was sent to live with an aunt a thousand miles away. He had no conscious memories of these events, but they haunted him. Through psychoanalysis, he was able to access these buried memories and “retranscribe” them. His recurring dream of searching for a lost object eventually changed.
He fell in love for the first time in his adult life.
Doidge draws on Eric Kandel’s Nobel Prize-winning work showing that learning changes the structure of neurons, and that psychotherapy is a form of learning. As Kandel put it: “Psychotherapy presumably does so through learning, by producing changes in gene expression that alter the strength of synaptic connections”.
Chapter 10: Rejuvenation
Frederick “Rusty” Gage and his team discovered that human brains continue to produce new neurons throughout life, a process called neurogenesis.
Remarkably, exercise, specifically running, doubled the number of new neurons in the hippocampus of mice. Learning didn’t create new neurons, but it did cause them to live longer.
The chapter profiles Dr. Stanley Karansky, a ninety-year-old who did brain exercises and noticed improvements in alertness, conversation, and even handwriting. As Doidge notes, “It’s a use-it-or-lose-it brain”.
Chapter 11: More Than the Sum of Her Parts
The book concludes with the story of Michelle Mack, a woman born with only half her brain. Her left hemisphere simply never developed.
Yet Michelle functions in the world. She holds a part-time job, reads, enjoys movies, and votes in elections. Her right hemisphere took over for her left, carrying out functions like speech and language.
She has some deficits, she struggles with abstract thinking and gets lost in unfamiliar places. But she also has savant-like abilities, including an extraordinary memory for dates and events.
Her story is perhaps the most powerful demonstration in the book of just how plastic the human brain can be. As Doidge writes: “Half a brain does not make for half a mind”.
The Brain That Changes Itself Analysis
Reading The Brain That Changes Itself was, for me, a genuinely transformative experience. I’ll be honest: I approached it with skepticism. I’ve read enough pop-science books that overpromise and underdeliver. But this one is different.
Doidge is not a neuroscientist—he’s a psychiatrist and psychoanalyst. This gives him a unique perspective. He’s not trying to sell a product or promote a particular lab’s research. He’s genuinely curious about how the mind and brain interact.
The book’s structure—telling stories through the scientists and patients themselves—makes complex neuroscience accessible without dumbing it down. As the Psychiatric Times review noted: “Dr Doidge is a fine writer, and his book has a lucid and engaging style. The text is thoroughly referenced, and most of the scientific claims are well substantiated”.
That said, the book has its critics. Some have argued that Doidge relies too heavily on anecdotal evidence. The CMAJ review noted that “some of the chapter headings seem somewhat sensationalistic and the book relies heavily on anecdotal accounts”. Others have criticized his Freudian perspective, particularly in the chapters on sexuality.
I found these critiques valid but not fatal. Doidge is writing for a general audience, not for a peer-reviewed journal. The case studies he presents are compelling, and many are backed by brain scan evidence. As the Psychiatric Times review concluded: “In general, I found Doidge’s conclusions quite persuasive”.
Strengths and Weaknesses
Strengths
1. Accessibility. Doidge has a gift for explaining complex neuroscience in plain English. He uses metaphors effectively without overdoing them.
2. Compelling stories. The case studies are unforgettable. Cheryl Schiltz, Barbara Arrowsmith Young, Michelle Mack—these are real people with extraordinary stories.
3. Scientific grounding. Despite the accessible style, the book is thoroughly referenced. Doidge interviewed the leading scientists in the field and presents their research accurately.
4. Practical implications. The book doesn’t just describe neuroplasticity, it shows how to harness it. From brain exercises to OCD treatment to stroke rehabilitation, the applications are concrete.
5. Broad scope. The book covers everything from learning disabilities to aging to sexual attraction to culture. It’s a comprehensive overview of a revolutionary field.
Weaknesses
1. Reliance on anecdote. Some readers will find the case study approach insufficiently rigorous. As one review noted, “may disappoint scholars of evidence-based medicine”.
2. Freudian bias. Doidge’s psychoanalytic background shows, particularly in the chapters on sexuality and psychotherapy. If you’re skeptical of Freud, parts of the book may feel dated.
3. Sensationalism. Some chapter headings are dramatic—”Midnight Resurrections,” “Brain Lock Unlocked.” The CMAJ review called them “somewhat sensationalistic”.
4. Over-reliance on individual scientists. Doidge sometimes presents his “neuroplasticians” as heroic figures without sufficient critical distance. The New York Times review noted his “breathless reverence”.
5. The “plastic paradox” could be explored further. Doidge acknowledges that neuroplasticity can lead to rigidity as well as flexibility, but this insight could be developed more fully.
Comparison with Similar Works
The Brain That Changes Itself sits alongside other popular neuroscience books like:
Oliver Sacks’s The Man Who Mistook His Wife for a Hat: Both books use case studies to explore neurological conditions. But while Sacks focuses on the strange and unusual, Doidge focuses on recovery and transformation.
Daniel Kahneman’s Thinking, Fast and Slow: Both explore how the mind works, but Kahneman focuses on cognitive biases while Doidge focuses on brain structure.
Matthew Walker’s Why We Sleep: Both are accessible science books, but Doidge covers a broader range of topics.
What sets Doidge apart is his focus on recovery and hope. This is not a book about what’s wrong with the brain, it’s a book about what the brain can do when given the right input.
Conclusion: Is The Brain That Changes Itself Worth Reading?
Yes, and I’d go further: I think this is one of the most important books of the twenty-first century.
Not because it’s perfect. It’s not. But because it fundamentally changes how we think about ourselves. For centuries, we’ve been told that our brains are fixed—that we’re stuck with what we’ve got. This book proves that’s wrong.
As the New York Times wrote: “The credo of this revolution is neuroplasticity—the discovery that the human brain is as malleable as a lump of wet clay not only in infancy… but well into hoary old age”.
The implications are staggering:
- Children with learning disabilities can rewire their brains
- Stroke victims can recover movement decades after their strokes
- The elderly can sharpen their memories
- People with OCD can rewire their brains without medication
- Amputees can eliminate phantom pain
But here’s the catch: neuroplasticity is a double-edged sword. The same property that allows us to recover from brain injury also allows us to develop bad habits, addictions, and rigid patterns of thinking. As Doidge writes, “Some of our most stubborn habits and disorders are products of our plasticity”.
The takeaway? Your brain is not fixed, but it’s also not automatically improving. You have to give it the right input. That means paying attention, practicing deliberately, and exposing yourself to new challenges.
If you’re ready to rethink what’s possible for your brain, The Brain That Changes Itself is the place to start.
