Hard is good…especially for brains

Here’s an interesting tip from Lumosity – brains like to be challenged. 

Huh?  I often think that my brain just wants to take it easy, take slow, and relaxxxx.  But maybe that’s just my laziness talking. Actually, after reading Dr. Eagleman’s book, Incognito, I have no idea which part of the brain I’m listening to any time…if that even makes sense.

One thing that Pam Zhang of the Lumosity blog asserts is that “Effective cognitive exercises must be both adaptive and novel in order to provide the brain with the challenges it needs.”

Does that mean that my standard Sudoku and crossword puzzles aren’t helping? Well, according to Ms. Zhang, they could be helping a lot more.

The analogy that seems to apply here is how we build muscles.  It’s hard to build muscles without a lot of straining, wheezing and hard work. Said differently, if all you do is walk around a bit, you don’t get a chiseled look and the ability to run a triathlon. So it is with brains, you don't get something for nothing - you got to make 'em wheez and struggle and work to build something. (Actually this whole idea of being able to build new brain cells is somewhat of a new idea. I suggest reading The Secret Life of the Middle-Aged Brain, by Barbara Strauch which does a great job of myth-debunking.)

Pam’s recent blog posting also says that you need to focus on brain exercises that are both adaptable and novel.

My sense of their use of the word “adaptable” is something more akin to “suitable”, as in something that’s just touch enough to make you work without getting hugely frustrated and quitting.  Early in my occupational therapy my therapist gave me a “find the words” assignment that I spent 4-5 hours on.  It was just way beyond my abilities at the time and I found the whole thing really discouraging.  The idea of a brain exercise seemingly within my grasp is something I’m much more interested in.

I get novelty, too.  The muscle analogy actually holds up pretty good here too.  We’ve learned that if we do the same exercises all the time, there’s just diminishing returns on a workout.  Your muscles know what to expect and are prepared for it, which is why P90X® in vogue right now. If my memory of “Mike and Mike in the Morning” commercials are accurate, they claim that one of the secrets is that it changes the workout every so often - they call it “muscle confusion” - so that your muscles don’t know what’s coming next.  I can imagine the same thing happening with my brain. (Actually my brain rarely knows what’s coming next.)

In fact, I find myself doing the same Lumosity exercises over and over again…even when I throw myself into a course (right now I’m on an well-needed “Attention” boost).

So I believe Ms. Zhang when she says that “The right kind of cognitive training introduces novel tasks that force the brain to process information in new ways”. So today I did my regular “Attention” boost and then tried “Rotation Matrix”.  I was lousy, which means, I guess, that if I stick with it for a while, I’ll build brain cells faster.

As I think about it, the really hard and un-fun part – the surgeries – are over. Now it’s time to embrace the fun hard parts.

Top Brain Books of 2011


As best I can tell, there’s a growing appetite for brain books. How can I tell?  Just amble down the aisle of a nearby book store (assuming that you can find one that’s solvent) and check out the titles.

If you like, well, brainy books about the brain, here’s my top two:
  • Incognito, David Eagleman, 2011
  • The Secret Life of the Middle-Aged Brain, Barbara Strauch, 2011
I really liked Barbara Strauch’s book about the middle-aged brain because it made me feel better about not being able to find my coffee cup (or cups depending upon the day).

And here’s two highly rated books that I haven’t read:
  • How the Brain Learns, David A. Sousa, 2011
  • Who's in Charge?: Free Will and the Science of the Brain by Michael Gazzaninga
I think that one of the great attractions of “science of the brain” books is that it’s unknown territory. The brain is extraordinarily complex, and we understand so little about the organ we use the most, that all these insights are a little bit like reading about astronauts and their exploits.

Now if you can’t find you cup of coffee and you’re scared to death about sliding down that slippery slope to geezerdom…or worse, you might want to read some books on improving brain performance. I haven't read any of these given my addiction to Lumosity, but here’s several you might want to check out:
  • Power Up Your Brain, David Perlmutter and Alberto Villoldo, 2011
  • Mensa 365 Brain Puzzlers Calendar 2011 by Mark Danna and Fraser Simpson (while I haven’t looked, I assume they have a 2012 edition coming out too.)
  • Brain Fitness for Women, Sondra Kornblatt and Jean Millican MD, 2012 (Ok, this hasn’t come out yet, but I thought I’d mention it anyways.)
Why all this interest in brain improvement?  I’m not sure, but I think that boomers are scared of losing their wits, their reputations and their place in the world. In this economy boomers are getting down-sized, out-placed and replaced. And if you can improve your “braininess” maybe you can stave off all of that. And while there is a certain “gravitas” that comes with age, there doesn’t seem to be a lot of other benefits, at least not in the business world.

Of course, there are also memoirs on real-life crises stemming from brain trauma and tumors. The only new one that I’m familiar with is Gabby’s new book which I just got Gabby’s book from the library and plan to dive into it shortly.
  • Gabby: A Story of Courage and Hope, Gabrielle Giffords, Mark Kelly and Jeffrey Zaslow, 2011

Dr. David Eagleman - The Carl Sagan of Brains

To me, Dr. Eagleman is the “Carl Sagan of Brains”. Why?  Because he is brain scientist who can explain the complex physiology of the brain to somebody like me who hasn't taken a science class since the 10th grade. I recommend it because, for those of us with medical brain issues, I find that we often focus on learning about the disease we have without learning about the brain itself.  

For example, his “Team of Rivals”[1] description of the workings of the brain helped me understand, when I’m arguing with myself, whom I’m arguing with. This happens to me the most when I want a piece of pie or bowl of ice cream but know that it’s not particularly good for me. Yes, this is almost a daily argument.

His commentary on how our actions are irrevocably tied to our biology, are particularly relevant to those of us that have had brain surgery.  In this arena, he discusses the behavioral changes of folks with brain tumors – an on-going topic on the American Brain Tumor Association and It’s Just Benign websites.
Is he controversial? Yes. Did I agree or even understand all his positions? No.

If you want to learn a bit more, before putting on reserve at your local library, I recommend that you listen to Terry Gross’ interview with Dr. Eagleman on her Fresh Air program: http://www.npr.org/2011/05/31/136495499/incognito-whats-hiding-in-the-unconscious-mind


[1] The book, Team of Rivals, was written by Doris Kearns Goodwin about Abraham Lincoln’s cabinet. If you like history books or the civil war, it’s well worth reading.
