You have been invited to an impor­tant fundrais­ing gala at your old col­lege and decided that this black-tie event demands a short col­lar super white Ital­ian shirt, like the one you bought years ago for your wed­ding. When you bravely tried the wed­ding shirt on (size 16), your wife noted that the col­lar suf­fo­cates you and you need about 1/4″ more space every­where in-between your neck and the col­lar all around your neck. What size shirt do you need to buy?  In case you don’t know the shirt size 16 means that a tape wrapped around your neck and two fin­gers posi­tioned flat upfront will mea­sure 16 inches.

You are spend­ing the sum­mer pol­ish­ing your the­sis in the uni­ver­sity library. Every day you take the esca­la­tor into the sub­way, turn right and catch a train going up North to the uni­ver­sity. One day you real­ize that the trains on your left going in the oppo­site direc­tion can bring you to the beach. It is sum­mer and noth­ing is wrong with some leisure. You care­fully cal­cu­late that even if you spend half of the remain­ing sum­mer vaca­tion in the library it should be enough to fin­ish the the­sis. You decide to spice up your sum­mer by Read the rest of this entry »

Archimedes made a plen­i­tude of sig­nif­i­cant sci­en­tific dis­cov­er­ies through­out his life. He designed machines capa­ble of lift­ing attack­ing ships out of the water as well as mir­ror arrays capa­ble of focus­ing sun rays and set­ting enemy ships on fire. He explained why and how bod­ies float in the water, help­ing the king ver­ify that his crown is indeed made out of pure gold. He was fas­ci­nated with infin­ity and found the way of approx­i­mat­ing the num­ber Pi as well as count­ing the num­ber of grains of sand that will fit inside the uni­verse. He died telling a Roman sol­dier that he is too busy to meet a gen­eral as he was con­tem­plat­ing yet another math­e­mat­i­cal dia­gram.  His tomb was dec­o­rated with his favorite dis­cov­ery .… What do you think it is?

As part of the research behind the book The Sharp­Brains Guide for Brain Fit­ness we inter­viewed dozens of lead­ing cog­ni­tive health and fit­ness sci­en­tists and experts world­wide to learn about their research and thoughts, and have a num­ber of take-aways to report.

What can we clearly say today that we couldn’t have said only 10 years ago? That what neu­ro­science pio­neer San­ti­ago Ramon y Cajal claimed in the XX cen­tury, “Every man can, if he so desires, become the sculp­tor his own brain”, may well become real­ity in the XXI.

And trans­form Edu­ca­tion, Health, Train­ing, and Gam­ing in the process, since Read the rest of this entry »

“What­ever you strug­gle with in a sense as it stems from your neu­rol­ogy, the inher­ent plas­tic­ity of the brain gives you a basis for improve­ment. This is a way under­uti­lized and under-appreciated resource that well all have.” Dr. Michael Merzenich on the Brain Sci­ence Pod­cast #54, 2/13/09.

Recently there has been grow­ing con­tro­versy about the effec­tive­ness of computer-based cog­ni­tive train­ing pro­grams. As a co-founder of Posit Sci­ence, Inc. Dr. Michael Merzenich is a staunch defender of the meth­ods his com­pany uses to val­i­date the pro­grams that they have devel­oped. But for the pur­poses of this essay, I want to share some of the key ideas we dis­cussed dur­ing his recent inter­view on the Brain Sci­ence Podcast.

First of all, I asked him to dis­cuss some of the high­lights of his long career. Since he was one of the first neu­ro­sci­en­tists to embrace the con­cepts of neu­ro­plas­tic­ity I was curi­ous about how this came about. While he did have some expo­sure to the ani­mal evi­dence as a grad­u­ate stu­dent, it was actu­ally his expe­ri­ence with the inven­tion of the cochlear implant that con­vinced Dr. Merzenich of the real-world, prac­ti­cal impli­ca­tions of brain plas­tic­ity. The qual­ity of the Read the rest of this entry »

Over the last year we have inter­viewed a num­ber of lead­ing brain health and fit­ness sci­en­tists and prac­ti­tion­ers world­wide to learn about their research and thoughts, and have news to report.

What can we say today that we couldn’t have said only 10 years ago? That what neu­ro­science pio­neer San­ti­ago Ramon y Cajal claimed in the XX cen­tury, “Every man can, if he so desires, become the sculp­tor his own brain”, may well become real­ity in the XXI. And influ­ence Edu­ca­tion, Health, Train­ing, and Gam­ing in the process.

We have only scratched the sur­face of what science-based struc­tured cog­ni­tive (i.e., men­tal) exer­cise can do for brain health and pro­duc­tiv­ity. We are now wit­ness­ing the birth of a new indus­try that crosses tra­di­tional sec­tor bound­aries and that may help us under­stand, assess and train our brains, har­ness­ing the grow­ing research about neu­ro­ge­n­e­sis (the cre­ation of new neu­rons), neu­ro­plas­tic­ity (the abil­ity of the brain to rewire itself through expe­ri­ence), cog­ni­tive train­ing and emo­tional regulation.

Let’s now debunk 10 myths, still too preva­lent, that may pre­vent us from see­ing the full poten­tial of this emerg­ing field:

Myth 1: It’s all in our genes.

Real­ity: A big com­po­nent of our life­long brain health and devel­op­ment depends on what we do with our brains. Our own actions, not only our genes, influ­ence our lives to a large extent. Genes pre­dis­pose us, not deter­mine our fates.

“Indi­vid­u­als who lead men­tally stim­u­lat­ing lives, through edu­ca­tion, occu­pa­tion and leisure activ­i­ties, have reduced risk of devel­op­ing Alzheimer’s. 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 Colum­bia University.

Myth 2: The field of Cognitive/ Brain Fit­ness is too new to be credible.

Real­ity: The field rests on solid foun­da­tions dat­ing back more decades — what is new is the num­ber and range of tools that are now start­ing to be avail­able for healthy individuals.

“Rig­or­ous and tar­geted cog­ni­tive train­ing has been used in clin­i­cal prac­tice for many years. Exer­cis­ing our brains sys­tem­at­i­cally is as impor­tant as exer­cis­ing our bod­ies.” — Dr. Elkhonon Gold­berg, neu­ropsy­chol­o­gist, clin­i­cal pro­fes­sor of neu­rol­ogy at New York Uni­ver­sity School of Med­i­cine, and dis­ci­ple of Alexan­der Luria.

“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 Beck, Direc­tor of the Beck Insti­tute for Cog­ni­tive Ther­apy and Research.

Myth 3: Med­ica­tion is and will remain the only evidence-based inter­ven­tion for a num­ber of brain-related problems.

Real­ity: Cog­ni­tive train­ing pro­grams are start­ing to Read the rest of this entry »

We had a very fun ses­sion titled Teach­ing Brain Fit­ness in Your Com­mu­nity at an Amer­i­can Soci­ety on Aging (ASA) con­fer­ence for health pro­fes­sion­als a cou­ple of weeks ago. Full house, with over 60 atten­dants and very good par­tic­i­pa­tion, show­ing great inter­est in the topic. I can’t wait to see the evaluations.

These are some of the resources I promised as a follow-up, which can be use­ful to every­one inter­ested in our field:

Dana Press kindly sent us a cou­ple of books. One of them, The Dana Guide to Brain Health: A Prac­ti­cal Fam­ily Ref­er­ence From Med­ical Experts, is our topic today.

We are impressed by what Dana is doing to insert neu­ro­science find­ings and impli­ca­tions into the pub­lic discourse.

No big sur­prise then, to find out so much qual­ity con­tent inside a 700-page one-of-a-kind guide, some of it, inci­den­tally, pro­vided by Dr. Gold­berg, our Chief Sci­en­tific Advisor.

The guide is really 4 books inside a com­mon bind­ing. Priced at a rea­son­able level, and with superb in-depth text and images in all rel­e­vant areas, the book can be used as a 1) Brain 101 tuto­r­ial, 2) brief sum­mary of the basics of Brain Care and Well­ness, 3) descrip­tion of the stages of brain devel­op­ment, 4) ref­er­ence guide for around 70 brain-related con­di­tions. In my per­sonal opin­ion, every neu­ro­science, med­ical and psy­chol­ogy stu­dent, clin­i­cian and researcher should have this book in their hands to keep abreast of many recent devel­op­ments, and also be exposed to pro­fes­sional devel­op­ment courses based on it. Many fam­i­lies and indi­vid­u­als inter­ested in the brain should con­sider buy­ing it too.

You have prob­a­bly heard about cog­ni­tive abil­i­ties or cog­ni­tion. What is cog­ni­tion? Cog­ni­tion has to do with how a per­son under­stands and acts in the world. It is a set of abil­i­ties, skills or processes that are part of nearly every human action.

Cog­ni­tive abil­i­ties are the brain-based skills we need to carry out any task from the sim­plest to the most com­plex. They have more to do with the mech­a­nisms of how we learn, remem­ber, problem-solve, and pay atten­tion rather than with any actual knowl­edge. Any task can be bro­ken down into the dif­fer­ent cog­ni­tive skills or func­tions needed to com­plete that task suc­cess­fully. For instance, answer­ing the tele­phone involves at least: per­cep­tion (hear­ing the ring tone), deci­sion tak­ing (answer­ing or not), motor skill (lift­ing the receiver), lan­guage skills (talk­ing and under­stand­ing lan­guage), social skills (inter­pret­ing tone of voice and inter­act­ing prop­erly with another human being).

The fields of neu­ropsy­chol­ogy, cog­ni­tive psy­chol­ogy, and thus cog­ni­tive train­ing are based on the frame­work that cog­ni­tion con­sists of dif­fer­ent men­tal func­tions or cog­ni­tive abil­i­ties which are based on spe­cific con­stel­la­tions of brain struc­tures. For instance mem­ory skills rely mainly on parts of the tem­po­ral lobes (next to the tem­ples) and parts of the frontal lobes (behind the forehead).

In the table below, you can browse through the main brain func­tions involved in cog­ni­tion. You will also find brain teasers that will help you chal­lenge all the cog­ni­tive abil­i­ties described: Learn and have fun!

COGNITIVE ABILITIES ARE MENTAL SKILLS

.

COGNITIVE ABILITIES CAN IMPROVE IF EXERCISED

With age, some cog­ni­tive abil­i­ties decline, espe­cially the exec­u­tive func­tions. In addi­tion, cog­ni­tive abil­i­ties that are not used reg­u­larly tend to dimin­ish over time. This may hap­pen at any age but is mostly observed in older age. For­tu­nately, these skills can also be improved at any age with reg­u­lar practice.

Fur­ther rel­e­vant and use­ful resources:

- An inter­view with Yaakov Stern, explain­ing what cog­ni­tive reserve is and how cog­ni­tive abil­i­ties can be improved through life­time experiences.
