Maximize the Cognitive Value of Your Mental Workout

February 21, 2008 by Alvaro Fernandez

Phys­i­cal fit­ness. Cognitive/ brain fit­ness. Both require nov­el­ty, vari­ety and chal­lenge. Pro­fes­sor Schlo­mo Breznitz, a sci­en­tif­ic and busi­ness leader in the cog­ni­tive fit­ness field, explains why, elo­quent­ly, below. Per­haps “we want change” real­ly means “we need change”. Enjoy!

Why are every­day life chal­lenges not suf­fi­cient to keep our brains fit?

– By Prof. Shlo­mo Breznitz

Often, when describ­ing the ben­e­fits of Mind­Fit to brain health, I am asked by peo­ple in the audi­ence whether this soft­ware is real­ly need­ed. After all, so they argue, life pro­vides con­tin­ues cog­ni­tive chal­lenges, which should suf­fice for ensur­ing brain fit­ness. From the moment we wake up until we go to sleep our brains have to attend to com­plex stim­uli, plan many activ­i­ties, some of them quite com­plex, and car­ry us through what­ev­er the day offers. These tasks should pro­vide suf­fi­cient “brain exer­cise” with­out the need to engage in spe­cif­ic men­tal workout.

This line of argu­ment sounds odd­ly famil­iar, since it is an exact dupli­ca­tion of claims made in the recent past against the need for phys­i­cal exer­cise. One jumps into the car and from the car and per­haps even climbs a few stairs before sit­ting in the chair, which should be enough to burn the calo­ries and keep fit.

Neuroplasticity 101 and Brain Health Glossary

September 10, 2007 by Alvaro Fernandez

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”.

fmri.jpgThanks 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.

MindFit by CogniFit, and Baroness Susan Greenfield

September 8, 2007 by Alvaro Fernandez

We are glad to see that Mind­Fit is final­ly mak­ing it into the pop­u­lar press, at least in the UK. The pro­gram is mak­ing big news in the UK (BBC, Times, Dai­ly Telegragh, Guardian…) because Baroness Susan Green­field, direc­tor of the Roy­al Insti­tu­tion and a well-respect­ed neu­ro­sci­en­tist, is endors­ing it. We eval­u­at­ed it last year andTwo In One Task liked what we saw, based on our 10-Ques­tion Check­list. Now, remem­ber that no pro­gram is “best”, but that dif­fer­ent pro­grams can be more appro­pri­ate for spe­cif­ic peo­ple and spe­cif­ic goals, so read the check­list first and take a lot at oth­er pro­grams too if you are in the mar­ket for “brain training”.

Mind­Fit is a soft­ware-based assess­ment and train­ing pro­gram for 14 cog­ni­tive skills impor­tant for healthy aging. We typ­i­cal­ly rec­om­mend it for peo­ple over 50 (up to any age, you sim­ply need to know how to use a com­put­er and a mouse) who want a nov­el and var­ied men­tal workout.

11 Neuroscientists Debunk a Common Myth about Brain Training

September 6, 2007 by Alvaro Fernandez

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):

Judith Beck “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.

James Zull“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.

Dr. Elkhonon Goldberg“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.

Picture of Daniel Gopher “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.

Yaakov Stern“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.

Go Hirano“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.

Picture of Brett Steenbarger “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.

torkel_s.jpg“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.

Bradley S. Gibson, Ph.D.“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.

Arthur Lavin“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.

David Rabiner“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.

Build Your Cognitive Reserve: An Interview with Dr. Yaakov Stern

July 23, 2007 by SharpBrains

Yaakov SternDr. Yaakov Stern is the Divi­sion Leader of the Cog­ni­tive Neu­ro­science Divi­sion of the Sergievsky Cen­ter, and Pro­fes­sor of Clin­i­cal Neu­ropsy­chol­o­gy, at the Col­lege of Physi­cians and Sur­geons of Colum­bia Uni­ver­si­ty, New York. Alvaro Fer­nan­dez inter­views him here as part of our research for The Sharp­Brains Guide to Brain Fit­ness book.

Dr. Stern is one of the lead­ing researchers of the Cog­ni­tive Reserve the­o­ry, which aims to explain why some indi­vid­u­als with full Alzheimer’s pathol­o­gy (accu­mu­la­tion of plaques and tan­gles in their brains) can keep nor­mal lives until they die, while oth­ers with the same amount of plaques and tan­gles dis­play the severe symp­toms we asso­ciate with Alzheimer’s Dis­ease. He has pub­lished dozens of peer-reviewed sci­en­tif­ic papers on the subject.

The con­cept of a Cog­ni­tive Reserve has been around since 1989, when a post mortem analy­sis of 137 peo­ple with Alzheimer’s Dis­ease showed that some patients exhib­it­ed few­er clin­i­cal symp­toms than their actu­al pathol­o­gy sug­gest­ed. These patients also showed high­er brain weights and greater num­ber of neu­rons when com­pared to age-matched con­trols. The inves­ti­ga­tors hypoth­e­sized that the patients had a larg­er “reserve” of neu­rons and abil­i­ties that enable them to off­set the loss­es caused by Alzheimer’s. Since then, the con­cept of Cog­ni­tive Reserve has been defined as the abil­i­ty of an indi­vid­ual to tol­er­ate pro­gres­sive brain pathol­o­gy with­out demon­strat­ing clin­i­cal cog­ni­tive symptoms.

Key take-aways

  • Life­time expe­ri­ences, like edu­ca­tion, engag­ing occu­pa­tion, and leisure activ­i­ties, have been shown to have a major influ­ence on how we age, specif­i­cal­ly on whether we will devel­op Alzheimer’s symp­toms or not.
  • This is so because stim­u­lat­ing activ­i­ties, ide­al­ly com­bin­ing phys­i­cal exer­cise, learn­ing and social inter­ac­tion, help us build a Cog­ni­tive Reserve to pro­tect us.
  • The ear­li­er we start build­ing our Reserve, the bet­ter; but it is nev­er too late to start. And, the more activ­i­ties, the bet­ter: the effect is cumulative.

The Cog­ni­tive Reserve

Alvaro Fer­nan­dez (AF): Dear Dr. Stern, it is a plea­sure to have you here. Let me first ask you this: the impli­ca­tions of your research are pret­ty broad, pre­sent­ing major impli­ca­tions across sec­tors and age groups. What has been the most unex­pect­ed reac­tion so far?

Brain Exercise for the Frontal lobes: the McKinsey Mind

May 1, 2007 by Alvaro Fernandez

My first full-time job was as a strate­gic con­sul­tant at McK­in­sey & Com­pa­ny. A very intense 2‑year learn­ing experience.

Their Alum­ni News Ser­vice recent­ly inter­viewed me and pub­lished this great arti­cle on Sharp­Brains. The writer does a superb job of pro­vid­ing an overview of what we do, so I rec­om­mend you read it. I’d like to empha­size the fol­low­ing quotes for any­one look­ing for jobs these days, so that “brain exer­cise” is part of the equation:

  • “Alvaro has some very high praise for the men­tal gym­nas­tics that the McK­in­sey expe­ri­ence pro­vides.  Giv­en that the frontal lobes in our brain (behind the fore­head) only mature in our late 20s, he says, the jobs we take in our ear­ly and mid-20s are very impor­tant not only for our career prospects, but also for our brain devel­op­ment fit­ness. This is the stage in our life where, con­scious­ly or not, we can improve our deci­sion-mak­ing, ini­tia­tive and self-reg­u­la­tion abil­i­ties, all of which lit­er­al­ly affect the phys­i­cal growth of our frontal lobes in a sig­nif­i­cant way.”
  • “Join­ing McK­in­sey as a BA is lit­er­al­ly like join­ing a brain gym, Alvaro says. “The demands of the McK­in­sey mod­el. [Read more…] about Brain Exer­cise for the Frontal lobes: the McK­in­sey Mind
