Update: Mind. Learn. Eat. Shape. Play

September 30, 2010 by SharpBrains

You may find that too much media cov­er­age on how to take good care of our brains is con­fus­ing, if not poten­tial­ly mis­lead­ing. In The True Sto­ry — is men­tal exer­cise good, bad, or irrel­e­vant, Dr. Pas­cale Mich­e­lon dis­sects for you a recent large study which was large­ly report­ed as bad news when in fact it brings good news (no mir­a­cles, but good news).  We hope you enjoy her insight­ful analy­sis — and all the excel­lent arti­cles that fol­low in the Sep­tem­ber edi­tion of our month­ly eNewslet­ter cov­er­ing cog­ni­tive health and brain fit­ness top­ics. Please remem­ber that you can use the box in the right col­umn to sub­scribe and receive this newslet­ter via email.

Do you Mind

Dear sapi­ens sapi­ens, do you mind: Dr. Joshua Stein­er­man encour­ages you to ask your­self the tough ques­tions: Do you mind your brain? Do you know your nog­gin’? Can you claim cere­bral own­er­ship or is your men­tal a rental? Plus, why we need a new lex­i­con for pos­i­tive cog­ni­tion interventions.

Time for a Cog­ni­tive Reserve Day: with 36 mil­lion peo­ple world­wide with demen­tia today and relat­ed care costs around 1 per­cent of the world’s gross domes­tic prod­uct (GDP), and grow­ing fast, may it be time to com­ple­ment World Alzheimer’s Day with Word Cog­ni­tive Reserve’s Day?

Food for Thought

Debunk­ing learn­ing styles: a recent arti­cle in The New York Times debunks many old myths about learn­ing and learn­ing styles, sum­ma­riz­ing emerg­ing cog­ni­tive neu­ro­science findings.

Sci­ence for the Peo­ple: quick now — think of a ques­tion, any ques­tion, that comes to mind. Chances are some one in the excel­lent ros­ter of 28 sci­ence blog­gers who took part in Sharp­Brains’ edi­tion of Sci­en­tia Pro Pub­li­ca blog car­ni­val answered it.

Food for Thought — II 

‘West­ern’ Style Diet Increas­es Risk of ADHD: Dr. David Rabin­er reports how, on the one hand, a recent large study track­ing 1172 Aus­tralian ado­les­cents and their par­ents found that dietary fac­tors can play an impor­tant role in the devel­op­ment of atten­tion deficits, at least for some children.

A Con­trolled Tri­al of Herbal Treat­ment for ADHD: on the oth­er hand, Dr. Rabin­er adds, a recent ran­dom­ized-con­trolled tri­al sup­ports the idea that appro­pri­ately pre­pared and tar­get­ed herbal com­pounds have the poten­tial to be ther­a­peu­tic and reduce atten­tion deficit symptoms.

Shap­ing the Future

Q&A about the new Sharp­Brains Coun­cil for Brain Fit­ness Inno­va­tion: we have received many good ques­tions about the new Sharp­Brains Coun­cil … here you are our answers.

Meet the Experts: since 2006 we have inter­viewed dozens of experts on the future of cog­ni­tive enhance­ment and men­tal health, build­ing up the foun­da­tion for the type of inno­va­tion the Sharp­Brains Coun­cil wants to fos­ter. Here you can find what 26 lead­ing-edge sci­en­tists and experts believe and why.

Get­ting ther­a­py through your iPhone: The Dai­ly Beast (a great new media out­let) just pub­lished this excel­lent arti­cle on an emerg­ing “small rev­o­lu­tion” in men­tal health care.

Minding the Aging Brain

February 20, 2008 by Dr. Joshua Steinerman

Cog­ni­tive train­ing (the basis for what we call “brain fit­ness” these days) has a wide array of appli­ca­tions. The most recentneurons one, which is cap­tur­ing pub­lic’s imag­i­na­tion, monop­o­liz­ing media cov­er­age, and cre­at­ing cer­tain con­fu­sion, is Healthy Brain Aging. We are for­tu­nate to have Dr. Joshua Stein­er­man, one of our new Expert Con­trib­u­tors, offer today his great voice to this con­ver­sa­tion. Enjoy!

Mind­ing the Aging Brain

– By Joshua R. Stein­er­man, M.D.

Sci­en­tists, philoso­phers, artists, and experts from all fields of human endeav­or lament: it ain’t easy get­ting old­er. It? Do they refer to frailty and dis­abil­i­ty? To bod­i­ly dis­ease? To life at its essence?

It’s all in your head

The mind is not set in stone, but it is encased by bone. It’s real­ly all about the brain, the hyphen in the mind-body conun­drum. That squishy gray neu­ronal jun­gle is the inter­face between inter­nal life and envi­ron­men­tal sen­sa­tions and stim­u­la­tion. As expect­ed, the brain shows signs of aging just as a wrin­kled brow, a stooped pos­ture, or an arthrit­ic fin­ger might. The most com­mon brain changes observed in aging and in age-asso­ci­at­ed neu­ropsy­chi­atric dis­ease include:

Math Brain Teaser: The Unkindest Cut of All, Part 1 of 2

April 27, 2007 by Caroline Latham

In hon­or of Math­e­mat­ics Aware­ness Month, here is anoth­er math­e­mat­i­cal brain ben­der from puz­zle mas­ter Wes Carroll.

The Unkind­est Cut of All, Part 1 of 2

Dif­fi­cul­ty: HARD
Type: MATH (Spa­tial)
Square

Ques­tion:
The area of a square is equal to the square of the length of one side. So, for exam­ple, a square with side length 3 has area (32), or 9. What is the area of a square whose diag­o­nal is length 5?

In this puz­zle you are work­ing out your spa­tial visu­al­iza­tion (occip­i­tal lobes), mem­o­ry (tem­po­ral lobes), and hypoth­e­sis gen­er­a­tion (frontal lobes).

Solu­tion:
12.5

Expla­na­tion:
I am espe­cial­ly fond of these two ways to solve this problem:

1. Draw the right tri­an­gle whose hypotenuse is the square’s diag­o­nal, and whose two legs are two sides of the square. Then use the Pythagore­an The­o­rem (a^2 + b^2 = c^2) to solve for the length of each side. Since two sides are equal, we get (a^2 + a^2 = c^2), or (2(a^2) = c^2) ). Since c is 5, 2(a^2) = 25, mak­ing a^2 equal to 25/2, or 12.5. Since the area of the square is a^2, we’re done: it’s 12.5.

2. Tilt the square 45 degrees and draw a square around it such the the cor­ners of the orig­i­nal square just touch the mid­dles of the sides of the new, larg­er square. The new square has sides each 5 units long (the diag­o­nal of the small­er square), and it there­fore has area 25. How­ev­er, a clos­er inspec­tion reveals that the area of the larg­er square must be exact­ly twice that of the small­er. There­fore the small­er square has area 25/2, or 12.5.
