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).

A Few Intru­sive Questions

The New Yorker April 30th issue includes a superb arti­cle on The Way We Age Now: Can med­i­cine serve an aging pop­u­la­tion?. Atul Gawande pro­vides a great (and a bit depress­ing) sur­vey on the geri­atrics field: more and more need for prac­ti­tion­ers, with less and less supply.

now, a cou­ple of quotes and data points that are very rel­e­vant to our efforts around healthy brain aging.

• “for most of our hundred-thousand-year existence—all but the past cou­ple of hun­dred years—the aver­age life span of human beings has been thirty years or less. (Research sug­gests that sub­jects of the Roman Empire had an aver­age life expectancy of twenty-eight years.)”
• “Inher­i­tance has sur­pris­ingly lit­tle influ­ence on longevity. James Vau­pel, of the Max Planck Insti­tute for Demo­graphic Research, in Ros­tock, Ger­many, notes that only six per cent of how long you’ll live, com­pared with the aver­age, is explained by your par­ents’ longevity; by con­trast, up to ninety per cent of how tall you are, com­pared with the aver­age, is explained by your par­ents’ height. Even genet­i­cally iden­ti­cal twins vary widely in life span: the typ­i­cal gap is more than fif­teen years.”

Fas­ci­nat­ing. First, let’s appre­ci­ate our incred­i­ble life expectancy today; we are lit­er­ally push­ing the envelop of how to main­tain healthy brains and bod­ies. By his­tor­i­cal stan­dards, many of us are liv­ing on “bor­rowed” time. Sec­ond, there you have some evi­dence for the impor­tance of our expe­ri­ence and our lifestyle on how long we live. In terms of healthy aging, on aver­age, nur­ture seems to be at least as impor­tant as nature, and the one more in our con­trol to take action today.
