Salon.com on Brain Fitness: Tree or Forest?

April 1, 2008 by Alvaro Fernandez

Salon.com pub­lished yes­ter­day a thought-pro­vok­ing arti­cle focused on Posit Sci­ence’s Brain Fit­ness Pro­gram, titled Buff Up Your Brain, that com­bined a) some pret­ty good analy­sis and great points about that spe­cif­ic pro­gram and jus­ti­fi­able (to a point) crit­i­cism of the com­mer­cial tone of a recent PBS Spe­cial, with b) the error of con­fus­ing a tree with the for­est, that led the author to make sev­er­al unwar­rant­ed claims regard­ing the field.

Com­put­er­ized cog­ni­tive train­ing has been around since way before Posit Sci­ence, and will be here way beyond Posit Sci­ence (and Sharp­Brains, and Salon.com), and their audi­to­ry pro­cess­ing prod­uct-fea­tured in the PBS Spe­cial- is not, in our view, the most par­tic­u­lar­ly impres­sive exam­ple. Well-direct­ed cog­ni­tive exer­cise can enhance men­tal skills and trans­fer to real-life out­comes, act­ing as a good com­ple­men­tary tool, when used prop­er­ly, to oth­er lifestyle options and tools.

Brain Training: No Magic Bullet, Yet Useful Tool. Interview with Elizabeth Zelinski

December 18, 2007 by Alvaro Fernandez

Sharon Beg­ley, Newsweek’s sci­ence reporter, recent­ly wrote that

- “With the nation’s 78 mil­lion baby boomers approach­ing the age of those dread­ed ‘“where did I leave my keys?” moments, it’s no won­der the mar­ket for com­put­er-based brain train­ing has shot up from essen­tial­ly zero in 2005 to $80 mil­lion this year, accord­ing to the con­sult­ing firm SharpBrains.

- “Now comes the largest and most rig­or­ous study of a com­mer­cial­ly-avail­able train­ing pro­gram, and it shows that there is hope for aging brains. This morn­ing, at the meet­ing of the Geron­to­log­i­cal Soci­ety of Amer­i­ca, sci­en­tists are pre­sent­ing data show­ing that after eight weeks of dai­ly one-hour ses­sions with Brain Fit­ness 2.0 from Posit Sci­ence, elder­ly vol­un­teers got mea­sur­ably bet­ter in their brain’s speed and accu­ra­cy of processElizabeth Zelinski IMPACTing.

We recent­ly had the chance to inter­view Dr. Eliz­a­beth Zelin­s­ki of the Uni­ver­si­ty of South­ern Cal­i­for­nia Andrus Geron­tol­ogy Cen­ter, who led the IMPACT (Improve­ment in Mem­o­ry with Plas­tic­i­ty-based Adap­tive Cog­ni­tive Train­ing) Study Sharon Beg­ley refers to in the quote above.

First, some con­text on this study, which is by far the largest high-qual­i­ty study of its kind. The study was prospec­tive, ran­dom­ized, con­trolled, and used a dou­ble blind tri­al. 524 healthy adults 65-year-old and over were divid­ed into two groups. One received an hour a day of train­ing for eight to ten weeks, and the oth­er spent the same amount of time watch­ing edu­ca­tion­al DVDs. The IMPACT study, fund­ed by Posit Sci­ence cor­po­ra­tion, was per­formed in mul­ti­ple loca­tions, includ­ing the Mayo Clin­ic, USCF, and San Fran­cis­co Vet­er­an Affairs Med­ical Center.

The dis­cus­sion cen­ters at his point on the ini­tial results that were pre­sent­ed Geron­to­log­i­cal Soci­ety of Amer­i­ca (the study has­n’t been pub­lished yet).

Alvaro Fer­nan­dez: Dr. Zelin­s­ki. Thank you for being with us. Could you start by set­ting the con­text and pro­vid­ing an overview of how human cog­ni­tive abil­i­ties typ­i­cal­ly evolve as we age based on insights from your Long Beach Lon­gi­tu­di­nal Study?

Eliz­a­beth Zelin­s­ki: Of course. The first con­cept to under­stand is that dif­fer­ent cog­ni­tive skills evolve over the lifes­pan in dif­fer­ent ways. Some that rely on expe­ri­ence, such as vocab­u­lary, actu­al­ly improve as we age. Some tend to decline grad­u­al­ly, start­ing in our late 20s. This hap­pens, for exam­ple, with pro­cess­ing speed (how long it takes us to process and respond to infor­ma­tion), mem­o­ry, and rea­son­ing. We could sum­ma­rize this phe­nom­e­non by say­ing that as we age we get bet­ter at deal­ing with the famil­iar, but worse at deal­ing with the new. We can always learn, but at a slow­er pace.

Are there any spe­cif­ic tip­ping or inflec­tion points in this trend, any age when the rate of decline is more pronounced? 

We don’t have a clear answer to that. It depends a lot on the indi­vid­ual. In gen­er­al it is a grad­ual, cumu­la­tive process, so that by age 70 we sta­tis­ti­cal­ly see clear age declines. Which, for exam­ple, is a strong fac­tor deter­min­ing why old­er adults strug­gle to adapt to new tech­nolo­gies, but why try­ing to learn them pro­vides need­ed men­tal stim­u­la­tion. Now we know that genes only account for a por­tion of this decline. Much of it depends on our envi­ron­ment, lifestyle and actions.

Can you sum­ma­rize what a healthy indi­vid­ual can do to slow down this process of decline, and help stay healthy and pro­duc­tive as long as possible?

One gen­er­al rec­om­men­da­tion is to do every­thing we can to pre­vent or delay dis­ease process­es, such as dia­betes or high-blood pres­sure, that have a neg­a­tive effect on our brains. For exam­ple, it is a tragedy in our soci­ety that we usu­al­ly reduce our lev­els of phys­i­cal exer­cise dras­ti­cal­ly after we leave school.

Let me then ask: what are the rel­a­tive virtues of phys­i­cal vs. men­tal exercise? 

Great ques­tion! That in fact leads into my sec­ond rec­om­men­da­tion. Aer­o­bic exer­cise has been shown to [Read more…] about Brain Train­ing: No Mag­ic Bul­let, Yet Use­ful Tool. Inter­view with Eliz­a­beth Zelinski

Physical and Mental Exercise: Why Pitch One Against the other?

December 11, 2007 by Alvaro Fernandez

Read­er There­sa Cerul­li just for­ward­ed this Let­ter to the Edi­tor that she had sent to the New York Times and went unpub­lished. The let­ter address­es the OpEd men­tioned here (pitch­ing phys­i­cal vs. men­tal exer­cise), and refers to the Cogmed work­ing mem­o­ry train­ing pro­gram, whose results have been stud­ied in mul­ti­ple papers pub­lished in top med­ical and sci­en­tif­ic jour­nals.

——————————-

Dear Edi­tor:

I applaud San­dra Aamodt and Sam Wang for throw­ing some cold water on the cur­rent brain fit­ness craze in their recent New York Times Mag­a­zine Opin­ion Edi­to­r­i­al “Exer­cise on the Brain.”  They are cor­rect in label­ing the host of “men­tal fit­ness” prod­ucts that tar­get aging baby boomers as “inspired by sci­ence ”  not to be con­fused with actu­al­ly proven by sci­ence. For the last 30 years, terms like “brain plas­tic­i­ty” have been wide­ly and casu­al­ly used, cre­at­ing hype that risks drown­ing out the real break­throughs that brain researchers are mak­ing in this area.

How­ev­er, I would like to dis­tin­guish the “men­tal fit­ness” trend that Aamodt and Wang right­ly crit­i­cize from actu­al researched-based cog­ni­tive train­ing such as the Cogmed pro­gram devel­oped in Swe­den. Unlike “men­tal fit­ness” pro­grams, cog­ni­tive train­ing pro­grams focus very nar­row­ly on spe­cif­ic cog­ni­tive func­tions that research has shown to be plas­tic. This is in stark con­trast to com­pil­ing a smat­ter­ing of exer­cis­es or activ­i­ties that are gen­er­al­ly thought to be [Read more…] about Phys­i­cal and Men­tal Exer­cise: Why Pitch One Against the other?

Use It or Lose It: What is the “It”?

September 12, 2006 by Alvaro Fernandez

Who has not heard “Use It or Lose It”.

Now, what is “It”?

And, is “It” only one thing or a num­ber of inte­grat­ed ele­ments, each of which are heav­i­ly involved in spe­cif­ic men­tal operations?

Let’s take a quick look:

The brain is com­posed of 3 “brains” or main sub-struc­tures, each named after the evo­lu­tion­ary moment in which the sub-sys­tem is believed to have appeared.

Theropod A) The Neo­cor­tex is the most recent area, where we per­form high-lev­el think­ing and com­plex inte­gra­tive tasks. Oth­er mam­mals do have this part too, but in much small­er pro­por­tion of the whole brain volume.

B) The Lim­bic Sys­tem, or Mam­malian Brain, crit­i­cal for emo­tions and for memory,

C) The Cere­bel­lum and Stem, or Rep­til­ian Brain, that reg­u­lates basic vital vari­ables such as breath­ing, heart­beat and motor coordination

 

Now some more details:

Theropod
B) Emo­tions are gen­er­at­ed in the lim­bic sys­tem, as well as the appetites and urges that (typ­i­cal­ly) help us sur­vive. For instance, the amyg­dala gets trig­gered to pre­pare us to deal with a threat­en­ing sit­u­a­tion, result­ing in our feel­ing of fear. The hip­pocam­pus is key in the for­ma­tion of mem­o­ry.

 

TheropodA) The Neo­cor­tex is com­posed of

  • Frontal Lobes: or the CEO of the Mind, for sophis­ti­cat­ed brain func­tions such as plan­ning and conceptualizing.
  • Pari­etal: deals with move­ment, the sens­es, and some forms of recog­ni­tion
  • Tem­po­ral: audi­to­ry process­es and language
  • Occip­i­tal: visu­al pro­cess­ing center

In action

When we exer­cise our brains, we put our Neu­rons in action. “Cells that fire togeth­er wire togeth­er” means that synapses–unions between neurons–get solid­i­fied the more often the respec­tive neu­rons “talk” to each oth­er. (Cred­it: Peter Furstenberg)
