Without operations or medications, they have made use of the brain's hitherto unknown ability to change. Some were patients who had what were thought to be incurable brain problems; others were people without specific problems who simply wanted to improve the functioning of their brains or preserve them as they aged.
For four hundred years this venture would have been inconceivable because 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; that when brain cells failed to develop properly, or were injured, or died, they could not be replaced.
Nor could the brain ever alter its structure and find a new way to function if part of it was damaged. The theory of the unchanging brain decreed that people who were born with brain or mental limitations, or who sustained brain damage, would be limited or damaged for life. Scientists who wondered if the healthy brain might be improved or preserved through activity or mental exercise were told not to waste their time, A neurological nihilism—a sense that treatment for many brain problems was ineffective or even unwarranted—had taken hold, and it spread through our culture, even stunting our overall view of human nature.
Since the brain. You've reached the end of this preview. Share this link with a friend: Other Related Materials 7 pages. That plasticity and variety also means that our sexuality is not hardwired, but is altered by our psychology and experience.
It could have been interesting when Norman Doidge says that sexual plasticity seem higher in those who have had many partners and in those couples who stayed together for a long time, but fails to dig deeper and provide any sort of proof.
Falling in love brings about huge changes in our brain. Especially when people commit to each other, they need to alter their existing lives as well, which is why for many love feels like a loss of identity. The author says that we do not fall with looks alone but with a host of attributes, including the ability of that other person to make us feel good.
Once in love, highly pleasurable emotional states are triggered that can make us fall in love even with defects of our partners, which made me think of days of Summer.
Norman Doidge says that oxytocin reinforces bonding in mammals and triggers trust. Contrary to dopamine that triggers sexual arousal and excites us, oxytocin makes calmer and warmer Sinek in Leaders Eat Last also talks about hormones.
Oxytocin is released when falling in love and when preparing to parent so that people can unlearn previous selfish-ier behavior and make space for the new partner and new baby.
Unlearning and changing at such a deep state also helps explain why so many people who fall in love with manipulative persons often end up being puppets and takes them years to recover. Especially important for sexual development are critical periods. Norman Doidge goes on a long tirade against pornography. He says pornography is addictive for its dopamine release and has negative repercussions for couples. People who get hooked often require kinkier and kinkier stuff or more and more violent and cannot get horny anymore with their partner without fantasizing about pornographic scripts.
The author speaks at length about a patience he had. The patient had a childhood where violence was common and her mom also had sexual encounters with him. He ended up mixing sex with violence and the two maps for sex and violence overlapped with each other. Doidge was able to disassociate the two maps by pointing out the difference between the two every time they came up in conversation, helping him see the difference and that he was capable of untangling sex from violence.
For a long time it was believed that there was little that patients could do to recover after a stroke. Of course, given our brain plasticity, that was quite wrong. Norman Doidge introduces Thaub and his research with monkeys. Basically monkeys who had had their arm deafferented -ie.: But Thaub had a genius idea: You don't get what you want - You get what you need Click To Tweet.
Thaub began treating people with strokes even long after they had stopped normal rehabilitation, and many showed large improvements even when their stroke happened more than 4 years before. A few are -like the one for colors-, but many are generic, so that our motor skills or computational skills for example, can be taken care in whichever part of the brain.
Norman Doidge talks about OCD, obsessions and neurosis here, which is super interesting. What happens from a neuroplasticity point of view is that a patient which indulges his worry by checking and re-checking that everything is OK only strengthen his fears and worries because he keeps firing those neurons over and over, making the neural connection more and more efficient. Worry begets worry, says Doidge. The author talks about Schwartz and his research to cure OCD.
Schwartz proposes that the patient, as soon as the worry comes up, tells himself that the problem is not whatever he is worried about, but the OCD episode. This will help him get some distance from his own brain chemical reactions. The struggle is not to make the feeling go away, but not to give in.
The next step is that the patient focuses instead on a new, pleasurable activity. The idea makes sense because instead of firing the worry neural connection it grows a new brain connection. Because of the use or lose it principle, the more the patient does it the more the new connection gets stronger and the weaker and weaker the worry connection gets. Because the patient should think about a pleasurable activity, he also gets rewarded with a dopamine release which helps growing the new neuronal connection even Seth Godin in Linchpin talks about how he overcame his little neurotic tendencies by refusing to double check and triple check the passport was in place and the key was in the pocket.
To read more on Schwartz and his researches this is his website. Norman Doidge explains here that plasticity is a property.
As a property, it can be good, or used in good ways, or it can be negative or used for negative purposes. The author then introduces Ramachandran and the phenomenon of phantom limbs, such as patient who lose a limb but keep feeling the limb is still there.
The whole idea also led to a simple revolution: Norman Doidge introduces Pascual-Leone researches and talks about the neuroplasticity of learning. He talks about a research from Pascual-Leone on people learning a new skills. Brain scans of students during the whole week showed that on Friday the brain maps had a dramatic expansion, only to return to normal size on Monday. Friday maps continued to grow for six months, but always returned to normal on Monday.
Monday maps were the opposite instead: The longer term Monday changes instead represent the new neural connection being formed. The two different speed also help understand a phenomenon we can all be familiar with: To learn long term we need to stay at a skill for longer I would link again here to Grit for more on the importance at staying at a skill and The Talent Code and Mastery on how to learn.
People training mentally on a skill were almost as good as people who actually trained physically for that skill. Both start as electrical impulses in our brain which then sends signals to our muscles. Experiments have already proven how people with electrodes in their brain could move objects connected to those electrodes, allowing us to imagine a future where paralyzed people can move objects around them.
Our brain is not disconnected from our body. Every thought leaves a trace by altering the shape of the brain itself.
The author poignantly ask: Pascual-Leone uses a great analogy: The slope, snow consistency and terrain beneath the slope are our genes, a given. Albeit the slope is partly given, we can steer the sledge to choose a path. The more we keep using those paths, the more we strengthen and the more we increase our chances of using them again.
Those are our habits, which can be good habits or bad ones. As Thaub showed with his research on OCD, to develop a new pathway, you have to block the other already existing ones. However, Doidge later explains, we can also shape our genes.
In this chapter Norman Doidge goes through a breathtaking real life case of a patient he cured. The patient goes beyond the walls he har erected to avoid dealing with the devastating pain. The Brain That Changes Itself deals with a very important topic as well: Our brains, like all other organs, gradually decline.
And yet it still goes under massive plastic reorganization. High IQ has been correlated to how well someone can recover from lost brain functions. It seems like having intelligence to spare allowed people to better restructure the brain.
The question is then why on earth should the left hemisphere limit our potential? Better to let go of the details and use that space for other activities.
