What is brain plasticity? It's a term that explains how brain functions aren't rigid and set in stone at an early age, but rather are changeable and adaptable. Put simply, an old dog CAN learn new tricks...but they need to apply themselves. It's "use it, or lose it."
In his return to the Brisbane Writers Festival, Norman Doidge gives an update on some of the latest findings relating to brain plasticity. He explains how understanding that the brain can change itself has huge potential for new treatments for neurological problems, and can also inform what we know about how the human brain grows, learns and adapts.
Doidge tells the remarkable story of how, in his last visit to Brisbane in 2008, he met a woman Jane Gapp whose daughter had the incurable condition Locked-In Syndrome. Reading Doidge's book compelled Gapp to persevere in her attempts to help her daughter recover, and she has since pulled her out of her "Locked-In" state.
Norman Doidge, M.D., is a psychiatrist, psychoanalyst, researcher, author, essayist and poet. He is on the Research Faculty at Columbia University's Center for Psychoanalytic Training and Research, in New York, and the University of Toronto's Department of Psychiatry. He is a native of Toronto.
Why is learning a second language more difficult after the onset of adolescence? Psychiatrist Norman Doidge explains that as we get older and master our first language, the competitive nature of brain plasticity deteriorates our ability to pick up a new one.
Capacity of neurons and neural networks in the brain to change their connections and behaviour in response to new information, sensory stimulation, development, damage, or dysfunction. Rapid change or reorganization of the brain's cellular or neural networks can take place in many different forms and under many different circumstances. Neuroplasticity occurs when neurons in the brain sprout and form synapses. As the brain processes sensory information, frequently used synapses are strengthened while unused synapses weaken. Eventually, unused synapses are eliminated completely in a process known as synaptic pruning, which leaves behind efficient networks of neural connections. Neuroplasticity occurs during development in childhood, following physical injury such as loss of a limb or sense organ, and during reinforcement of sensory information such as in learning. Neuroplasticity forms the basis of research into brain-computer interface technology, in which computers are designed to interact with the brain to restore sensation in people with an impaired sense such as the loss of vision. Research on neuroplasticity is also aimed at improving scientists' understanding of how to reactivate or deactivate damaged areas of the brain in people affected by stroke, emotional disorders, chronic pain, psychopathy, or social phobia; such research may lead to improved treatments for these conditions.
To those who haven't read articles or books much on the new findings in the field of neuroscience, this talk might not be convincing. However, Norman Doidge's talk is based on and supported by many neuroscientists' recent reserach work.
I am appalled by many mistakes in this talk.
(a) He says Russian revolution took a century? This guy needs a history lesson.
(b) He says Electricity (specifically Electro-mechanical aspects) as still work in progress. In fact, electro-mechanical aspect is one of the best known in realm of engineering and physics. This guy needs a lesson from physics.
(b)He stressed how Westerners brains are differently from Asians. How he found out? From few Asian graduate students....He was inferring something about very diverse Asian populations from study of few Asian graduate students!!! I'd be happy had he simply stated findings from that particular study but it was absolute mistake to infer for entire population from extremely low sample value.
This guy needs a lesson from statistics. In fact, the last mistake is very dangerous!!
This talk was an absolute waste of time for me.
