Brain Plasticity in Adults

posted by Cheryl Petersen

Until recently, it has been believed in mainstream neuroscience, that plasticity in the brain is present only in children. The younger years are considered critical in brain development because once we become an adult, the brain wiring is permanent, localized. Therefore, parts of the brain have been mapped. Localizationist, Torsten Wiesel, won the Nobel Prize for determining where visual processing occurs in the adult brain.

But, along comes experimental and open-minded Michael Merzenich, to discover that plasticity is found in the adult brain also. However, Nobel Prize winner, Torsten Wiesel opposed the idea and his opposition frustrated Merzenich because many other neuroscientists automatically accepted the position of the peer majority supported by Wiesel, even though the position was arrogant and weak.

Years later, Wiesel did accept adult brain plasticity and did graciously acknowledge in print that for a long time he was wrong and that Merzenich’s brave experiments ultimately commanded attention. In other words, Wiesel’s brain changed.

But, what did other hardcore localizationists do? They believed in adult brain plasticity because Wiesel did.

I learned two lessons from this real life story: One, when I am wrong, gracefully, publicly admit it and move forward with an appreciation and respect for the brave soul who brought the wrongness to my attention. Two, think for myself and don’t believe someone because they are technically in a position of authority.

Control is more than controlling someone or something
In the Bible, the book of Job portrays a man, Job, who gets robbed of everything by the Devil. Everything human beings consider to be good and deserving gets taken away by the Devil. As Job lay in bed suffering, his friends visit. The older friends start psychobabbling as to why Job is in his pre

One chip is enough
Marketing experts adapt people to the habit of eating not just one chip, but the whole bag. The problem with this doctrine is we get fat and confused. Many year ago, by sheer circumstance I was recuperating from an accident and found I just couldn’t eat very much at a time. One chip, or rather
