Thank you for your inter­est and atten­tion and have a great December.

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?

The use of a vari­ety of brain train­ing inter­ven­tions is grow­ing in the area of men­tal health. Emerg­ing evi­dence sug­gests that in the near future tar­geted brain train­ing may even be used to pre­vent sub­stance abuse. For exam­ple, train­ing work­ing mem­ory may reduce sub­stance abusers’ dis­count­ing of long-term rewards and pun­ish­ments — such dis­count­ing is one of the rea­sons why peo­ple sus­cep­ti­ble to addic­tions do not ben­e­fit from tra­di­tional informational/ edu­ca­tional approaches to drug prevention.

Let’s explore some expand­ing appli­ca­tions of brain train­ing, and much more, in this lat­est edi­tion of the monthly Sharp­Brains eNewslet­ter.

Brain Train­ing and Men­tal Health

ADHD: Brain Train­ing, Neu­ro­feed­back, Diet, and More: What can be done to fight ADHD and improve the lives of peo­ple suf­fer­ing from it?

Brain Train­ing and Schiz­o­phre­nia: Social cog­ni­tive train­ing pro­grams can boost schiz­o­phren­ics’ skills social skills.

Rethink­ing the Clas­si­fi­ca­tion of Men­tal Ill­ness: How can we rethink the clas­si­fi­ca­tion of psy­chopathol­ogy (via the new DSM-5) to reflect our cur­rent under­stand­ing of the brain as a dynamic system?

Upcom­ing events: Cog­ni­tive Reme­di­a­tion in Psy­chi­a­try (June 10th, NYC), Enter­tain­ment Soft­ware and Cog­ni­tive Neu­rother­a­peu­tics Soci­ety (Sep­tem­ber 19–20, San Francisco).

Lifestyle for Brain Health

More Friends, Big­ger Brain: The num­ber of friends you have could be pre­dicted by the size of our amygdala!

Music and Demen­tia: Play­ing music pro­tects the brain later on. Music may also be used to teach new facts to peo­ple suf­fer­ing from dementia.

Exer­cise and Over­weight Chil­dren: Aer­o­bic exer­cise can boost over­weight chil­dren exec­u­tive functions.

The Brain Grows With Prac­tice…: We know that when the brain mas­ters a new skill, tar­geted brain areas/ cir­cuits get enlarged. We now know that those areas and cir­cuits even­tu­ally shrink back to nor­mal, but per­for­mance gain can be maintained!

Brain Teaser

Can you lis­ten to these laughs and dis­tin­guish whether it is a human or a com­puter laugh­ing? Also, given how good laugh­ing is…how about try­ing this to find out how much stressed you are? You may be surprised.

Laugh­ing feels good. Laugh­ing is indeed good in most cases. A good belly laugh amounts to an aer­o­bic exer­cise as your blood pres­sure and heart rate increase, your breath­ing changes and your diaphragm con­tracts. Laugh­ing has also been shown to boost the immune sys­tem and reduce stress.

Laugh­ing is thus good for your brain! Here are two fun ways to take a fur­ther look at laugh­ter and the brain :

• Lis­ten to these laughs and decide whether it is a human or a com­puter laughing.
• Try this to find out how much you are stressed. You may be surprised…

Enjoy!

The 2011 Sharp­Brains Vir­tual Sum­mit (March 30th — April 1st) gath­ered more than 260 research and indus­try lead­ers from 16 coun­tries for 3 days to dis­cuss the chang­ing land­scape of Brain Health and Cog­ni­tive Fit­ness. It was a great suc­cess! Find the key lessons and take-home points from the Sum­mit in these 2 arti­cles by Drs. Jamie Wil­son and Luc Beau­doin, respec­tively: 10 Emerg­ing Themes:  Why Brain Health Sta­tus Quo is Not an Option and 7 Key Lessons from the Sharp­Brains Sum­mit.

Con­sider this: “Col­lab­o­ra­tion is emerg­ing in ways that were unthink­able only a few years ago. Researchers are open­ing up their data and method­olo­gies to gain insights from one another. Com­mer­cial orga­ni­za­tions are part­ner­ing via dig­i­tal chan­nels, con­tent syn­di­ca­tion and other areas of best prac­tice. Social entre­pre­neurs and local prac­ti­tion­ers are shar­ing  moti­va­tional tips and edu­ca­tional resources in their efforts to build pro­grams from the bot­tom up.  Open inno­va­tion is dri­ving a bet­ter mar­ket­place for con­sumers. All these col­lab­o­ra­tive efforts are the seeds of suc­cess­ful inno­va­tion, and despite still being in the foothills, it would seem bet­ter to go hand in hand, than tak­ing a lonely road.”

We hope the arti­cles of this free newslet­ter will help you think about the future and your own role in shap­ing it as a pro­fes­sional and/ or a life­long learner.
