As promised in my pre­vi­ous post on Neu­ro­ge­n­e­sis and Brain Plas­tic­ity in Adult Brains, I will now list some inter­views, video, arti­cles, and books that go hand-in-hand with these fas­ci­nat­ing top­ics we are dis­cussing. Please com­ment below if you have favorite addi­tional resources!

I apol­o­gize for the long delay in get­ting back to this col­umn but I have a good excuse. We just recently had a baby, and boy, that takes care right there of the phys­i­cal exer­cise need. Between car­ry­ing the baby upstairs and down­stairs, run­ning to get the baby, get­ting out of the bed and pick­ing the baby up and putting the baby down a cou­ple of times a night no you need not worry about get­ting your daily exer­cise dose in…Now, the major­ity of the answers to my post on the brain virtues of phys­i­cal exer­cise sug­gests that most peo­ple think that the brain ben­e­fits of phys­i­cal exer­cise are mostly to be under­stood as com­ple­men­tary effects of a healthy life style.

Is this cor­rect? In my post today I will attempt to answer this question.

First, while gen­er­ally health­ier peo­ple seem to have health­ier brains, the phys­i­cal exer­cise effect on the brain seems to be inde­pen­dent of other things. One of the most impor­tant devel­op­ment in neu­ro­science was when the offi­cial dogma claim­ing that there was no neu­ro­ge­n­e­sis (pro­duc­tion of new brain cells) in the adult brain was top­pled. Now we know that the brain is “plas­tic” mean­ing that, under the right cir­cum­stances, the brain can change Read the rest of this entry »

Back in July, I wrote a post enti­tled 10 Brain Tips To Teach and Learn. Those tips apply to stu­dents of any age, includ­ing adults, for ide­ally adults are still learn­ers. Why is adult learn­ing rel­e­vant in a brain-focused blog, you may wonder:

The short of it

As we age, our brain:

still forms new brain cells
can change its struc­ture & func­tion
finds pos­i­tive stress can be ben­e­fi­cial; neg­a­tive stress can be detri­men­tal
can thrive on novel chal­lenges
needs to be exer­cised, just like our bodies

The long of it

Adults may have a ten­dency to get set in their ways have been doing it this way for a long time and it works, so why change? Turns out, though, that change can be a way to keep aging brains healthy. At the April Learn­ing & the Brain con­fer­ence, the theme of which was neu­ro­plas­tic­ity, I attended sev­eral ses­sions on adult learn­ing. Here’s what the experts are saying.

Over the last year we have gladly seen an avalanche of news on adult neu­ro­ge­n­e­sis (the cre­ation of new neu­rons in adult brains), fol­low­ing recent research reports. Fur­ther, we have seen how the news that phys­i­cal exer­cise can enhance neu­ro­ge­n­e­sis is becom­ing com­mon knowl­edge among many health sys­tems we work with.

Now, the obvi­ous ques­tion that doesn’t always get asked is, “What good are new neu­rons if they don’t sur­vive?”. And that’s where learn­ing, enrich­ment, men­tal exer­cise, are critical.

We are glad to intro­duce a new Expert Con­trib­u­tor, Dr. Bill Klemm, a pro­fes­sor of Neu­ro­science at Texas A&M Uni­ver­sity, who sum­ma­rizes much research on how new neu­rons are born-and what they need to live long happy lives.

New Neu­rons: Good News, Bad News

– By Dr. Bill Klemm

In the last few years, researchers have dis­cov­ered that new nerve cells (neu­rons) are born, pre­sum­ably from resid­ual stem cells that exist even in adults. That should be good news for all of us as we get older and fear men­tal decline. The bad news is that these new neu­rons die, unless our minds are active enough.

Bran­don Keim writes a nice post on The Future Sci­ence of Altru­ism at Wired Sci­ence Blog, based on an inter­view with Jor­dan Graf­man, chief of cog­ni­tive neu­ro­science at the National Insti­tute of Neu­ro­log­i­cal Dis­or­ders and Stroke.

Bran­don pro­vides good con­text say­ing that “Sci­en­tists, said Graf­man, are under­stand­ing how our brains are shaped by cul­ture and envi­ron­ment, and a mech­a­nism of these changes may involve fluc­tu­a­tion in our genes them­selves, which we’re only begin­ning to under­stand”. (more on this in our post Richard Dawkins and Alfred Nobel: beyond nature and nur­ture).

And gives us some very nice quotes from Dr. Graf­man, including

• “One of the ways we dif­fer­en­ti­ate our­selves from other species is that we have a sense of future. We don’t have to have imme­di­ate grat­i­fi­ca­tion.… But how far can we go into the future? How much of our brain is aimed at doing that? […]”
• “Other great apes have a frontal lobe, fairly well devel­oped, but not nearly as well devel­oped as our own. If you believe in Dar­win and evo­lu­tion, you argue that the area grew, and the neural archi­tec­ture had to change in some way to accom­mo­date the abil­i­ties asso­ci­ated with that behav­ior. There’s no doubt that didn’t occur overnight; prob­a­bly a slow change, and it was one of the last areas of the brain to develop as well. It’s very recent evo­lu­tion­ary devel­op­ment that humans took full advan­tage of. What in the future? What in the brains can change?”
• “The issue becomes — do we teach this? Train peo­ple to do this? Chil­dren tend to be self­ish, and have to be taught to share.”

The UC Berke­ley mag­a­zine Greater Good tries to answer that ques­tion with a series of arti­cles on Grat­i­tude. I espe­cially enjoyed A Les­son in Thanks, described as Read the rest of this entry »
