Dear Mr or Mrs Next US President,

We are glad to wel­come you to our blog car­ni­val. After a short hia­tus, Encephalon is back and gath­er­ing steam. We have pre­pared this “revival” edi­tion just for you, so you can be well informed and impress us all dur­ing the upcom­ing Sci­encede­bate 2008.

With­out fur­ther ado, let’s pro­ceed to the ques­tions posed by 24 blog­gers on neu­ro­science and psy­chol­ogy issues. We hope they pro­vide, at the very least, good men­tal stim­u­la­tion for you and your advisors.

Big Ques­tions

Do I deserve to vote even if I don’t have Free Will? (Marc at Neu­ro­sci­en­tif­i­cally Challenged).

If cul­ture sculpts our brains, what can our brains do to refine our cul­ture first? (Stephanie at Brains On Purpose).

Is God more than a fly­ing brain? (Jes­sica at bioephemera).

Is Your brain really read­ing This? (Pete at Brain Hammer).

A Few Intru­sive Questions

Do you play any musi­cal instru­ment? (Megan at SharpBrains).

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.”

We Never For­get Any­thing (Any­more) (Pre­ven­tion Magazine)

- “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 »

Neu­ro­plas­tic­ity: the brain’s abil­ity to reor­ga­nize itself by form­ing new con­nec­tions through­out life. (see more con­cepts in our Glos­sary).

We coudn’t be hap­pier about the grow­ing num­ber of books pop­u­lar­iz­ing the key lessons about brain train­ing that Dr. Elkhonon Gold­berg has been research­ing and writ­ing about for years, and that moti­vated us to embark our­selves in the Sharp­Brains adventure.

Dis­cover Mag­a­zine presents a great arti­cle, Rewiring the Brain, review­ing two recent books.

• The sub­ti­tle is “Neu­ro­plas­tic­ity can allow for treat­ment of senil­ity, post-traumatic stress, ­obsessive-compulsive dis­or­der, and depres­sion and Bud­dhists have been cap­i­tal­iz­ing on it for mil­lenia.” I would add that the strong value of life­long learn­ing present in jesuit and jew­ish tra­di­tions reflects the same wis­dom. Some quotes:
• “Two new books, Train Your Mind, Change Your Brain (Bal­lan­tine Books, $24.95) by sci­ence jour­nal­ist Sharon Beg­ley and The Brain That Changes Itself (Viking, $24.95) by psy­chi­a­trist Nor­man Doidge, offer mas­ter­fully guided tours through the bur­geon­ing field of neu­ro­plas­tic­ity research. Each has its own style and empha­sis; both are excellent.”
• “Finally, both authors con­clude that adult neu­ro­plas­tic­ity is a vastly under­tapped resource, one with which West­ern med­i­cine and psy­chol­ogy are just now com­ing to grips. An impor­tant emerg­ing research agenda is to Read the rest of this entry »
