Very intense week, and very fun. I will be writ­ing more about this week’s 3 speak­ing events, but let me say now that our key messages

1) our brains remain flex­i­ble dur­ing our lifetimes,

2) we can refine our brains with tar­geted practice,

3) good brain exer­cise, or “men­tal cross-training”, requires nov­elty, vari­ety, and increas­ing level of chal­lenge (but with­out cre­at­ing too much stress),

are being very well accepted from both healthy aging and work­place pro­duc­tiv­ity points of view. We have ONE brain: health and pro­duc­tiv­ity are 2 sides of the same coin.

If you want to make sure we learn more about our brains, you can help fel­low blog­ger Shel­ley Batts get a col­lege schol­ar­ship by voting here. She has a great neu­ro­science blog, is now final­ist in a com­pe­ti­tion to win a nice schol­ar­ship, and needs out help.

Have some more time? You can watch this excellent 90-second video of cog­ni­tive neu­ro­sci­en­tist Dr Lisa Sak­sida doing yoga in front of the fire while explain­ing the nature of Brain and Mind (via Mind­Hacks). Quotes:

“I wish peo­ple under­stood that there is no mind/brain dual­ity. Specif­i­cally, I wish peo­ple under­stood that there is no such thing as a purely psy­cho­log­i­cal dis­or­der. Every event in your psy­cho­log­i­cal life, and there­fore every psy­cho­log­i­cal change, is reducible in the­ory to events and changes in your brain. We should there­fore not judge peo­ple dif­fer­ently, accord­ing to whether they are con­sid­ered to have a ‘psy­cho­log­i­cal’ as opposed to a ‘neu­ro­log­i­cal’ problem.”

“Of course, a lack of mind/brain split does not mean that we should aban­don all talk of psy­chol­ogy. Psy­chol­ogy and neu­ro­science are two ways of study­ing the same thing, and both are essen­tial for under­stand­ing the human condition.”

Given the grow­ing num­ber of arti­cles in the pop­u­lar press men­tion­ing words such as “neu­ro­plas­tic­ity”, “fMRI” and “cog­ni­tive reserve”, let’s review some key find­ings, con­cepts and terms.

First, a pre­scient quote by Span­ish neu­ro­sci­en­tist San­ti­ago Ramon y Cajal (1852–1934): “Every man can, if he so desires, become the sculp­tor his own brain”.

Thanks to new neu­roimag­ing tech­niques, regarded “as impor­tant for neu­ro­science as tele­scopes were for astron­omy, neu­ro­sci­en­tists and cog­ni­tive psy­chol­o­gists have been find­ing that the brain has a num­ber of “core capac­i­ties” and “men­tal mus­cles” that can be exer­cised through nov­elty, vari­ety and prac­tice, and that exer­cis­ing our brain can influ­ence the gen­er­a­tion of new neu­rons and their con­nec­tions. Brain exer­cise is being rec­og­nized, there­fore, as a crit­i­cal pil­lar of brain health, together with nutri­tion, phys­i­cal exer­cise and stress management.

Pre­vi­ous beliefs about our brain and how it works have been proven false. Some beliefs that have been debunked include claims that adult brains can not cre­ate new neu­rons (shown to be false by Berke­ley sci­en­tists Mar­ian Dia­mond and Mark Rosen­zweig, and Salk Institute’s Fred Gage), notions that work­ing mem­ory has a max­i­mum limit of 6 or 7 items (debunked by Karolin­ska Insti­tute Torkel Kling­berg), and assump­tions that the brain’s basic processes can not be reor­ga­nized by repeated prac­tice (UCSF’s Drs. Paula Tal­lal and Michael Merzenich). The “men­tal mus­cles” we can train include atten­tion, stress and emo­tional man­age­ment, mem­ory, visual/ spa­tial, audi­tory processes and lan­guage, motor coor­di­na­tion and exec­u­tive func­tions like plan­ning and problem-solving.

Men­tal stim­u­la­tion is impor­tant if done in the right sup­port­ive and engag­ing envi­ron­ment. Stanford’s Robert Sapol­sky has proven that chronic stress and cor­ti­cal inhi­bi­tion, which may be aggra­vated due to imposed men­tal stim­u­la­tion, may prove coun­ter­pro­duc­tive. Hav­ing the right moti­va­tion is essential.

A sur­pris­ing and promis­ing area of sci­en­tific inquiry is Mindfulness-Based Stress Reduc­tion (MBSR). An increas­ing num­ber of neu­ro­sci­en­tists (such as Uni­ver­sity of Wisconsin-Madison’s Richard David­son) are inves­ti­gat­ing the abil­ity of trained med­i­ta­tors to develop and sus­tain atten­tion and visu­al­iza­tions and to work pos­i­tively with pow­er­ful emo­tional states and stress through the directed men­tal processes of med­i­ta­tion practices.

And now, some keywords:

Brain Fit­ness Pro­gram: struc­tured set of brain exer­cises, usu­ally computer-based, designed to train spe­cific brain areas and processes in tar­geted ways.

Chronic Stress: ongo­ing, long-term stress, which blocks the for­ma­tion of new neu­rons and Read the rest of this entry »

Last Mon­day, NPR (very good US-based radio sta­tion) had a pro­gram on “do brain train­ing pro­grams work?” that reflected very old-fashioned think­ing. In short, the guest speak­ers talked and talked about the impor­tance of nutri­tion and phys­i­cal exer­cise (both very impor­tant, as we have cov­ered in this blog mul­ti­ple times), and expressed skep­ti­cism about the con­cept of exer­cis­ing our brains to improve atten­tion, mem­ory and other skills…I guess it takes a while to change old men­tal par­a­digms (And yes, some pro­grams work bet­ter than others).

Neu­ro­sci­en­tists have finally debunked that old think­ing that our brains decline inex­orably after a cer­tain age with lit­tle each of us can do to “exer­cise” or “train our brains”. But don’t trust me. Dur­ing the last year I have had the for­tune to inter­view 11 cutting-edge neu­ro­sci­en­tists and cog­ni­tive psy­chol­o­gists on their research and thoughts. Here are some of my favorite quotes (you can read the full inter­view notes by click­ing the links):

“Today, thanks to fMRI and other neu­roimag­ing tech­niques, we are start­ing to under­stand the impact our actions can have on spe­cific parts of the brain.”- Dr. Judith S. Beck, Direc­tor of the Beck Insti­tute for Cog­ni­tive Ther­apy and Research, and author of The Beck Diet Solu­tion: Train Your Brain to Think Like a Thin Per­son. Full Inter­view Notes.

“Learn­ing is phys­i­cal. Learn­ing means the mod­i­fi­ca­tion, growth, and prun­ing of our neu­rons, con­nec­tions called synapses and neu­ronal net­works, through experience…When we do so, we are cul­ti­vat­ing our own neu­ronal net­works. We become our own gar­den­ers — Dr. James Zull, Pro­fes­sor of Biol­ogy and Bio­chem­istry at Case West­ern Uni­ver­sity. Full Inter­view Notes.

“Exer­cis­ing our brains sys­tem­at­i­cally is as impor­tant as exer­cis­ing our bod­ies. In my expe­ri­ence, “Use it or lose it” should really be “Use it and get more of it”.- Dr. Elkhonon Gold­berg, neu­ropsy­chol­o­gist, clin­i­cal pro­fes­sor of neu­rol­ogy at New York Uni­ver­sity School of Med­i­cine, and dis­ci­ple of the great neu­ropsy­chol­o­gist Alexan­der Luria. Full Inter­view Notes.

“What research has shown is that cog­ni­tion, or what we call think­ing and per­for­mance, is really a set of skills that we can train sys­tem­at­i­cally. And that computer-based cog­ni­tive train­ers or“cognitive sim­u­la­tions are the most effec­tive and effi­cient way to do so. — Dr. Daniel Gopher, Direc­tor of the Research Cen­ter for Work Safety and Human Engi­neer­ing at Tech­nion Insti­tute of Sci­ence. Full Inter­view Notes.

“Indi­vid­u­als who lead men­tally stim­u­lat­ing lives, through edu­ca­tion, occu­pa­tion and leisure activ­i­ties, have reduced risk of devel­op­ing Alzheimer’s symp­toms. Stud­ies sug­gest that they have 35–40% less risk of man­i­fest­ing the dis­ease– Dr. Yaakov Stern, Divi­sion Leader of the Cog­ni­tive Neu­ro­science Divi­sion of the Sergievsky Cen­ter at the Col­lege of Physi­cians and Sur­geons of Colum­bia Uni­ver­sity, New York. Full Inter­view Notes.

“It is hardly deni­able that brains enchant Japan­ese peo­ple. We love brain train­ing. Dentsu, the biggest adver­tis­ing agency, announced the No.1 Consumer-chosen 2006 Prod­uct was game soft­ware and books for brain train­ing.”- Go Hirano, Japan­ese exec­u­tive, founder of NeuWell. Full Inter­view Notes.

“Elite per­form­ers are dis­tin­guished by the struc­tur­ing of their learn­ing process. It is impor­tant to under­stand the role of emo­tions: they are not “bad”. They are very use­ful sig­nals. It is impor­tant to become aware of them to avoid being engulfed by them, and learn how to man­age them. — Dr. Brett Steen­barger, Asso­ciate Pro­fes­sor of Psy­chi­a­try and Behav­ioral Sci­ences, SUNY Med­ical Uni­ver­sity, and author of Enhanc­ing Trader Per­for­mance. Full Inter­view Notes.

“We have shown that work­ing mem­ory can be improved by train­ing…I think that we are see­ing the begin­ning of a new era of com­put­er­ized train­ing for a wide range of appli­ca­tions.  Dr. Torkel Kling­berg, Direc­tor of the Devel­op­men­tal Cog­ni­tive Neu­ro­science Lab at Karolin­ska Insti­tute. Full Inter­view Notes.

“Train­ing is very impor­tant: atten­tional con­trol is one of the last cog­ni­tive abil­i­ties to develop in nor­mal brain development…I can eas­ily see the rel­e­vance in 2 fields. One, pro­fes­sional sports. Two, mil­i­tary train­ing.  Pro­fes­sor Bradley Gib­son is the Direc­tor of the Per­cep­tion and Atten­tion Lab at Uni­ver­sity of Notre Dame. Full Inter­view Notes.

“I don’t see that schools are apply­ing the best knowl­edge of how minds work. Schools should be the best place for applied neu­ro­science, tak­ing the lat­est advances in cog­ni­tive research and apply­ing it to the job of edu­cat­ing minds. — Dr. Arthur Lavin, Asso­ciate Clin­i­cal Pro­fes­sor of Pedi­atrics at Case West­ern School of Med­i­cine, pedi­a­tri­cian in pri­vate prac­tice. Full Inter­view Notes.

“Cog­ni­tive train­ing rests on solid premises, and some pro­grams already have very promis­ing research results. Some of the most are promis­ing areas are: neu­ro­feed­back, which as a whole is start­ing to present good research results, and work­ing mem­ory train­ing. — Pro­fes­sor David Rabiner, Senior Research Sci­en­tist and the Direc­tor of Psy­chol­ogy and Neu­ro­science Under­grad­u­ate Stud­ies at Duke Uni­ver­sity: Full Inter­view Notes.

There is much we can do every­day to lit­er­ally exer­cise our brains. No mat­ter our age. So much to Learn…so Good to Learn! Let’s see when this story makes it into NPR.

We were very happy to dis­cover that Sci­en­tific Amer­i­can Mind has high­lighted Sharp­Brains in their June/July 2007 issue!

Here’s what they had to say:

“Every­one knows the impor­tance of stay­ing phys­i­cally fit. But what about stay­ing men­tally fit? Research in the past sev­eral years has shown that men­tal “work­outs” may improve mem­ory, relieve stress and even help stave off Alzheimer’s. This new site is an online gym for the mind, offer­ing a blog about the sci­ence of brain fit­ness and links to rel­e­vant research. It also sells “exer­cise” soft­ware and offers per­sonal training.”
