If I’d known when I was in therapy how our precious brains work, how we should take the reins and ride through the landscape of our minds, fertilizing the land to grow healthy brain cells, would I have reached this state of inner peace sooner?
In this story I shared ways to rewire our brains; to keep them growing with the language and images by which we communicate with that powerhouse inside our skulls. I also shared some neurobic exercises to keep our brains fit.
I was awestruck and grateful that you, dear readers, loved that story. Your interest has motivated me to write more about the plasticity of our brains — a fascination that has helped me stay out of depression for almost 19 years.
Understanding how this universe in my head works has been instrumental in coping with episodes of “down” time. I know I’m the conductor; it’s up to me to produce the symphony. I can step back and observe the various members of this Infinite Orchestra.

Let’s head back to when this scientific knowledge first emerged.
The Discovery of Neurogenesis
Until the early 1970’s scientific circles widely accepted that once you reached adulthood, the brain cells (nerve cells or neurons) you possess are finite. That’s it. That’s your ration.
In addition, the belief was that our brains are divided into departments, staffed by neurons appointed for their expertise in a particular function, and who may not transfer to another department.
A leading pioneer in neuroplasticity in the 1970’s is Professor Michael Merzenich PhD, author of “Soft Wired: How the New Science of Brain Plasticity Can Change Your Life” (2013). He was conducting experiments to demonstrate that the hypothesis in the previous paragraph was correct.
“He was trying to prove that if there was damage to one part of the brain, because it had a fixed function, that skill could not be relearned. His neuroplasticity discovery proved the exact opposite. The brain is one big learning tissue. The skills previously learned by damaged tissue can be relearned in other parts of the brain.” — Gemm Learninghttps://youtu.be/o98crZWauPI
Your brain has a cortical map for your feet, hands, and every other part of the body. Dr. Merzenich found that if one cortical map is deprived of its input, this situation wasn’t permanent. Later, it could become active once again if something stimulated other nearby cortical maps. This process occurs because of neuroplasticity; Brain’s ability to adapt to change.
Here’s an example of what someone can achieve.
In 1972, more than a decade before I met him, my husband and soulmate was a victim of a serious car accident, thanks to a drunken teenager. He couldn’t talk and he couldn’t walk. Broken and burnt below the knees.
He spent 18 months in hospital during which he taught himself to talk. And he walked again despite one leg being shortened with pins and the other having all toes except the big one amputated because of gangrene.
He’d been trying to convey to the medical staff that there was something wrong under the plaster cast on his leg using hand and facial gestures. By the time they caught on, they wanted to amputate the lower leg; he refused but let them take his toes.
Despite being told the damage to his brain was irreversible, he didn’t believe them. Losing who he was before motivated him to learn to talk and walk again. This is the power we have over our minds!
(PS He gave me permission to share this story.)
“Algorithms have done better than brain plasticity at enabling paralyzed people to send a cursor to a target using thought alone.” — The Economist, Technology Quarterly, January 2018.
The advances in neuroscience and technology create possibilities we would have relegated to the realm of science fiction four decades ago. For instance, we wouldn’t be researching and developing
- bionic eyes
- brain-controlled prosthetic limbs
- BCI (Brain Computer Interface) development such as the cochlear implant, a hearing device which Michael Merzenich helped develop.
- NLP (Neuro Linguistic Programming) was created by Richard Bandler and John Grinder in California (where else?) in the 1970s; an approach to personal development, communication and psychotherapy which identifies patterns of thoughts and behaviors.
I’m excited about the family of health benefits that this marriage creates!

Am I neurotic about neurobics? Well, yes, I’m obsessed with good emotional, physical and spiritual health for all of us.
