Your Brain Lifting Weights

Increasingly science is coming to the opinion that the brain can be effectively trained, like a muscle.

 

If you’re like me, the idea that neurons, ganglia, dendrites and synapses, can get stronger-faster-better through regular mental sweating sounds like another case for Dr. Obvious. But in fact the state of the art for most of my lifetime was that the human cognition peaked at, oh, say age 35, and then began a long (hopefully slow) slide into senescence. How fast or slowly that happened depended in the main on our genetic inheritance.  

 

But remember, state of the art science until 1661(!) was that the earth and all its matter at its most elemental was comprised of earth, air, fire, and water. That’s what Aristotle posited in the fourth century BC. So great was his genius that it wasn’t until the 17th Century…nearly two millennia later… that Irish chemist Robert Boyle called this premise into question with the publication of his book The Sceptical Chymist, which presaged the modern theory of chemical elements.

 

In other words, sometimes science gets its mind around an idea and won’t let go no matter the evidence to the contrary.

 

But in the last few decades especially, it’s becoming clear that new brain cells born in mature brains “integrate into existing neuronal circuitry, providing the brain with a continual reservoir of youthful active cells. Such cells might then replace older neurons or possibly be used to reshape the brain so it may learn and adapt to new experiences.”

 

So new brain cells grow in mature brains and replace the old ones, which possibly (I say likely) allows us to continue to learn things as we age.

 

So how can we learn as we age? Current science suggests that “exposure to complex experiences boost the components that process information in the brain. Brain cell survival increases, the neural appendages that receive communication signals grow and the connections between cells multiply. Some of these changes occur not only during the brain’s early growth stage, but also in later years. A severe lack of mental exercise and even stressful experiences, however, limit the brain plan.”

 

What constitutes ‘exposure to complex experiences?’ Or, to continue the analogy, what gives your brain a workout? That’s the 100 billion brain cell question.

 

For me it’s travel to new places (preferably in Italy where I can get plenty of gelato), games, reading or listening to books and magazines, researching and writing, physical exercise, watching documentaries on TV, taking formal coursework, using brain workout software, learning new career skills, and getting friendly again with my dictionary and encyclopedia.

 

Since, by most estimates, 75 percent of all learning is informal, there’s almost certainly more.

 

One big bonus to mental workouts, after exercising my brain I don’t have to shower with a bunch of strangers!
