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 »

Spon­sored Ad (How to Adver­tise on SharpBrains.com)

Time for the Octo­ber edi­tion of the monthly Sharp­Brains eNewslet­ter, fea­tur­ing this time sev­eral arti­cles on the impact of stress, emo­tions, and self-regulation, on our brain’s struc­ture and performance.

We are pleased to bring to Sharp­Brains read­ers a new 6-part series on the Neu­ro­bi­ol­ogy of Stress, based on a recent book by Sharp­Brains con­trib­u­tor Dr. Jerome Schultz. The first two parts are already avail­able: Part 1 — The Human Brain and How It Responds to Stress and Part 2 — Gray Mat­ters.

Brain Study Links Emo­tional Self-Regulation and Math Per­for­mance: A new study strongly sug­gests the need to “help stu­dents reap­praise the sit­u­a­tion and con­trol emo­tions before they even get into a task”. While the study focused on math anx­i­ety and per­for­mance, the impli­ca­tions are rel­e­vant out­side the class­room too.

Reminder: Brain Fit­ness Q&A Ses­sions in Novem­ber: As we announced a few weeks ago, we are hon­ored to present an upcom­ing Brain Fit­ness Q&A Series. The first ses­sion, fea­tur­ing Dr. Gary Small, will take place Novem­ber 1st, 2011, 2-3pm US Eeast­ern Time. Please mark your cal­en­dar and join us at sharpbrains.com then! (no need to do any­thing prior to the session).

Music Train­ing Can Enhance Ver­bal Intel­li­gence and Exec­u­tive Func­tion: Very inter­est­ing new study pub­lished in Psy­cho­log­i­cal Sci­ence on the value of music train­ing (vs. sim­ply lis­ten­ing to music).

Gam­ing and Neu­ro­science: Oppor­tu­ni­ties and Chal­lenges: A sum­mary of impres­sions by researcher  Aki Niko­laidis based on his par­tic­i­pa­tion in the recent con­fer­ence Enter­tain­ment Soft­ware and Cog­ni­tive Neu­rother­a­peu­tics Con­fer­ence (ESCoNS) at the Uni­ver­sity of Cal­i­for­nia San Francisco.

– Don’t try this with your part­ner, or you may fight.
– How many col­ors do you see in The Her­mann Grid?
– This is less obvi­ous than it may appear.
– Is this a cir­cle or what?
– Are these 2 rows par­al­lel?
– What do you see?

(Editor’s Note: every other Fri­day, start­ing today, we’ll pub­lish a brain teaser to exer­cise our brains a bit. Here you have one sub­mit­ted by new con­trib­u­tor Maria Lando. Enjoy!).
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?

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…

Who will Ben­e­fit From Train­ing?  New research shows that mea­sur­ing brain activ­ity pat­terns can pre­dict who may ben­e­fit most from tran­ing inter­ven­tions –and who may not. Please note that the Kramer lab involved in this research is now offer­ing a post­doc­toral fellowship.

A Quick Test to Detect Ath­letes’ Con­cus­sions:  This new test can be per­formed at the side­line of sport­ing events to help detect con­cus­sions by look­ing at dif­fer­ent types of eye movements.

The Best Way to Learn: Tak­ing a test in which you recall what you have read seems to be a much bet­ter strat­egy than either study­ing the mate­r­ial repeat­edly or draw­ing detailed dia­grams of what you are learning.

Brain Teaser

Let us first announce an upcom­ing Vir­tual Book Club Dis­cus­sion focused on Brain Fit­ness, to take place on Mon­day March 14th in honor of Brain Aware­ness Week 2011 (March 14-20th). Let’s dis­cuss burn­ing issues together: Why care about neu­ro­plas­tic­ity and the pos­si­bil­i­ties it offers to enrich our qual­ity of life? What does cog­ni­tive reserve research mean to the way we learn, work, play, live? What is Brain Train­ing — and what is not? All the con­ver­sa­tion be vir­tual, via social media tools. You can learn more here.

This edi­tion of Sharp­Brains monthly eNewslet­ter brings many arti­cles on those top­ics. Enjoy! Read the rest of this entry »

Mem­ory is more com­plex that we usu­ally think. Cog­ni­tive sci­ences have iden­ti­fied dif­fer­ent mem­ory sys­tems, each sup­ported by dif­fer­ent brain regions. One major dif­fer­ence is between long-term and short-term mem­ory (also called work­ing memory).

Long-term mem­ory is an unlim­ited stor­age of mem­o­ries dat­ing as far back as you can remem­ber to a few min­utes ago. For instance, when you remem­ber your first day in high-school or what you said to your col­league two min­utes ago, you are using your long-term mem­ory sys­tem. This sys­tem depends mostly on parts of the tem­po­ral (in blue here) and frontal (in green) regions of the brain.

Short-term or work­ing mem­ory is a lim­ited stor­age used to briefly keep the infor­ma­tion needed for the task at hand. For instance, when you keep in mind a phone num­ber while you are dial­ing it or when you do some men­tal cal­cu­la­tion you are using your work­ing mem­ory sys­tem. This sys­tem depends mostly on parts of the frontal (in green) and pari­etal (in yel­low) regions of the brain.

Work­ing mem­ory is cru­cial for most of the tasks we per­form daily. It is also quite vul­ner­a­ble to the aging process. Two good rea­sons to try to main­tain this func­tion! Ready to test and sharpen your short-term memory?

Fol­low this link to mem­o­rize series of let­ters. The first 2 tri­als are very easy but the test gets quite chal­leng­ing after that!

How can we help younger gen­er­a­tions find the right path to life­long brain health and per­for­mance — espe­cially as they will live longer, and in more dynamic, com­plex envi­ron­ments? We cre­ated the Brain Health across the Lifes­pan series to curate reli­able sources of infor­ma­tion, and here you can  check out  the Top 10 Resources to Bet­ter Under­stand the Teenage Brain.
