This blog post was inspired by the book, The Scientific American Brave New Brain.1 When I was a graduate student I learned that the brain was hardwired like a machine or a computer (which were much less common in those days). This was dogma that was not challenged. It was widely accepted and affected the way that people who suffered strokes or other brain traumas were treated. The belief was that once the damage was done, little more could be done than to teach the victim how to deal with the remaining functionality that was left. Recent research has refuted this dogma and the term neuroplasticity has become the norm. The brain is remarkably plastic or flexible. And if one part of the brain is damaged, another part of the brain can frequently take over that function. An earlier Healthymemory blog post, “Transactive Memory: An Aid to Short and Long Term Memory and to Stroke Recovery” addressed some issues regarding stroke, and subsequent posts will address it further.

Brave New Brain states that the current consensus is that “your brain is changing every second in response to the environment and mind.” The Healthymemory Blog strongly concurs. Brave New Brain also states that tomorrow you change and mold your brain as you want and need. Now here the Healthymemory Blog would argue that already today you can change and mold your brain as you want and need. Indeed, if the brain is changing every second in response to the environment and your mind, you can change and mold your brain by selecting the environment in which it operates and the manner in which your mind wakes. Presumably Brave New Brain is implying that the future will bring technology, for example chemicals or electronic means of stimulating the brain, that will facilitate your changing and molding your brain as you want and need. The prospects of this happening will be discussed in future posts, but you need to realize that today you can change and mold your brain as you want and need. True there are limitations. You might want to change your brain so that you can invent means of travel that exceed the speed of light. Nevertheless, your brain holds enormous potential that you should not overlook.

This admonition certainly applies to young people. However, it also applies to older people, including we Baby Boomers. We are not done learning. Our goal should be not only to ward off cognitive decline and dementia, but to continue to learn, create, and grow cognitively. We can change and mold our brains by choosing how we apply them. There are vast resources available in what the Healthymemory Blog terms transactive memory. Transactive memory refers to all the information that is external to your own biological brain. Included here is the information stored in the biological brains of other humans, and all the information stored in the libraries of the world, and, of course, the internet. There are three types of transactive memory. Accessible transactive memory is information that you know exists and can readily access. Available transactive memory is information that you know exists but that you cannot readily access. This is information that needs to be searched for and sought. Then there is potential transactive memory, which is all the information you have not yet discovered. You should note that the Healthymemory has a whole category of posts on transactive memory.

You should also note that there is another category of Healthymemory Blog posts on Mnemonic Techniques. Mnemonic techniques are specific strategies for learning difficult material, especially information that lacks or is deficient in inherent meaning. It is also believe that these techniques can serve as healthy mental exercises. The “Human Memory: Theory and Data” category includes posts such as this current one. As the title suggests it addresses human memory and also includes posts on common cognitive errors and how they can be avoided.
