Round-up of recent arti­cles on neu­ro­science, brain devel­op­ment and cog­ni­tive health:

Encephalon 68: A car­ni­val of neu­ro­science:

Chris hosts a great col­lec­tion of neu­ro­science and psy­chol­ogy posts in his sig­na­ture Q&A style.

Bilin­gual Babies Get Head Start — Before They Can Talk:

- Unlike the mono­lin­gual group, the bilin­gual group was able to suc­cess­fully learn a new sound type and use it to pre­dict where each char­ac­ter would pop up.

- The bilin­gual babies’ skill applies to more than just switch­ing between lan­guages. Mehler likened this appar­ently enhanced cog­ni­tive abil­ity to a brain select­ing “the right tool for the right oper­a­tion” also called exec­u­tive function.

- In this basic process, the brain, ever flex­i­ble, nim­bly switches from one learned response to another as sit­u­a­tions change.

- Mono­lin­gual babies hone this abil­ity later in their young lives, Mehler suggests.”

Study shows how kids’ stress hurts mem­ory:

“Now, research is pro­vid­ing what could be cru­cial clues to explain how child­hood poverty trans­lates into dim­mer chances of suc­cess: Chronic stress from grow­ing up poor appears to have a direct impact on the brain, leav­ing chil­dren with impair­ment in at least one key area — work­ing memory.”

Return­ing troops get­ting tested for brain injuries:

- “More than 150,000 ser­vice mem­bers from the Marines, Air Force, Army and Navy have under­gone the test­ing that became manda­tory last year. Those who suf­fer a con­cus­sion or sim­i­lar head injury will get a follow-up test.”

Dia­betes ‘impact on brain power’:

- “Fail­ure to con­trol type 2 dia­betes may have a long-term impact on the brain, research has suggested.

- Lead researcher Dr Jackie Price said: “Either hypos lead to cog­ni­tive decline, or cog­ni­tive decline makes it more dif­fi­cult for peo­ple to man­age their dia­betes, which in turn causes more hypos.

- “A third expla­na­tion could be that a third uniden­ti­fied fac­tor is caus­ing both the hypos and the cog­ni­tive decline.”

A roundup of sev­eral excel­lent arti­cles this week:

Keep­ing Your Brain Fit (US News and World Report)

- “In a study of more than 2,800 peo­ple ages 65 or older, Har­vard researchers found that those with at least five social ties—church groups, social groups, reg­u­lar vis­its, or phone calls with fam­ily and friends—were less likely to suf­fer cog­ni­tive decline than those with no social ties.”

- “The work­ing hypoth­e­sis is that it has some­thing to do with stress man­age­ment,” says Mar­i­lyn Albert, a neu­ro­sci­en­tist at Johns Hop­kins and codi­rec­tor of the Alzheimer’s research cen­ter there. In ani­mal stud­ies, a pro­longed ele­va­tion in stress hor­mones dam­ages the hip­pocam­pus. Social engage­ment appears to boost people’s sense of con­trol, which affects their stress level. Cre­ative arts seem to be a highly promis­ing way to increase social engage­ment. George Wash­ing­ton University’s Cohen has found that elderly peo­ple who joined choirs also stepped up their other activ­i­ties dur­ing a 12-month period, while a non­sing­ing con­trol group dropped out of some activ­i­ties. The singers also reported fewer health prob­lems, while the con­trol group reported an increase.”

- “Pro­cess­ing new infor­ma­tion when we’re anx­ious is tough; the stress itself is a dis­trac­tion. Fer­nan­dez taught Lau­rie this relax­ation trick: Read the rest of this entry »

Today is Inter­na­tional Women’s Day 2007.

Global con­sult­ing com­pany Accen­ture orga­nized a series of events, and I was for­tu­nate to lead a fun work­shop on The Neu­ro­science of Stress and Stress Man­age­ment in their San Fran­cisco office, help­ing over 125 accom­plished women (and a few men) learn what stress is, its impli­ca­tions for our brain func­tion­ing, per­for­mance and health, and of course some tips and tech­niques to develop our “stress man­age­ment” mus­cles. It was an honor to be able to wrap up a great event that included Dis­trict Attor­ney Kamala D. Har­ris, two of the co-authors of This is Not the Life I Ordered, a video by Sen­a­tor Dianne Fein­stein, and some great Accen­ture women.
