New­born Neu­rons — Even in the Adult Aging Brain — Are Crit­i­cal for Mem­ory (Sci­ence Daily):

“Newly gen­er­ated, or new­born neu­rons in the adult hip­pocam­pus are crit­i­cal for mem­ory retrieval, accord­ing to a study led by Stony Brook Uni­ver­sity researchers…Previous research… has demon­strated that new­born neu­rons form con­nec­tions with exist­ing neu­rons Read the rest of this entry »

Aer­o­bic exer­cise is the kind of exer­cise that has been con­sis­tently shown to trig­ger the growth of both brain cells and new con­nec­tions between them, boost­ing cog­ni­tive func­tions. It has also been asso­ci­ated with lower risks of devel­op­ing Alzheimer’s Dis­ease. Is it the case that other types of phys­i­cal exer­cise can also ben­e­fit the brain? Evi­dence is more lim­ited, but a new study sug­gests that weight train­ing may be a likely can­di­date to do so. Read the rest of this entry »

I just had the chance to dis­cuss lat­est neu­ro­sci­en­tific research and think­ing with Dr. Yaakov Stern, one of the lead­ing sci­en­tists study­ing how to build a neu­ro­pro­tec­tive cog­ni­tive reserve across the lifes­pan. Dr. Stern leads the Cog­ni­tive Neu­ro­science Divi­sion at the Colum­bia Uni­ver­sity Sergievsky Cen­ter. What fol­lows is a Q&A ses­sion con­ducted via email over the last week.

Alvaro Fer­nan­dez: What do you make of the recent study “Asso­ci­a­tion of Life­time Cog­ni­tive Engage­ment and Low β-Amyloid Depo­si­tion”? 

Yaakov Stern: I find these results very intrigu­ing. The con­cept of cog­ni­tive reserve posits that Read the rest of this entry »

As our final arti­cle for 2011, let us repur­pose one of Sharp­Brains’ most pop­u­lar blog posts since 2006. It may give you a few point­ers to sharpen those New Years Res­o­lu­tions. Let’s sum­ma­rize some lifestyle guide­lines we can all fol­low to enhance and main­tain a sharp brain through life...

1. Learn what is the “It” in “Use It or Lose It”. A basic under­stand­ing will serve you well to appre­ci­ate your brain’s beauty as a liv­ing and constantly-developing dense for­est with bil­lions of neu­rons and synapses.
2. Take care of your nutri­tion. Did you know that the brain only weighs 2% of body mass but con­sumes over 20% of the oxy­gen and nutri­ents we intake? As a gen­eral rule, you don’t need expen­sive ultra-sophisticated nutri­tional sup­ple­ments, just make sure you don’t stuff your­self with the “bad stuff”.
3. Remem­ber that the brain is part of the body. Things that exer­cise your body can also help sharpen your brain: phys­i­cal exer­cise enhances neurogenesis.
4. Prac­tice pos­i­tive, future-oriented thoughts until they become your default mind­set and you Read the rest of this entry »

(Editor’s note: Path­ways respon­si­ble for higher-order think­ing in the pre­frontal cor­tex (PFC), or exec­u­tive cen­ter of the brain, remain vul­ner­a­ble through­out life—during crit­i­cal early-life devel­op­men­tal win­dows, when the PFC fully matures in the early 20s, and finally from declines asso­ci­ated with old age. At all ages, phys­i­cal activ­ity and PFC-navigated social con­nec­tions are essen­tial com­po­nents to main­tain­ing brain health. The Expe­ri­ence Corps, a community-based social-engagement pro­gram, part­ners seniors with local schools to pro­mote purpose-driven involve­ment. Par­tic­i­pat­ing seniors have exhib­ited imme­di­ate short-term gains in brain regions vul­ner­a­ble to aging, such as the PFC, indi­cat­ing that peo­ple with the most to lose have the most to gain from envi­ron­men­tal enrichment.)

Over the last decade, sci­en­tists made two key dis­cov­er­ies that reframed our under­stand­ing of the adult brain’s poten­tial to ben­e­fit from life­long envi­ron­men­tal enrich­ment. First, they learned that the adult brain remains plas­tic; it can gen­er­ate new neu­rons in response to phys­i­cal activ­ity and new expe­ri­ences. Sec­ond, they con­firmed the impor­tance of social con­nect­ed­ness to late-life cog­ni­tive, psy­cho­log­i­cal, and phys­i­cal health. The inte­gra­tion of these find­ings with our under­stand­ing of indi­vid­u­als’ devel­op­men­tal needs through­out life under­scores the impor­tance of the “social brain.” The pre­frontal cor­tex (PFC) is par­tic­u­larly inte­gral to nav­i­gat­ing com­plex social behav­iors and hier­ar­chies over the life course.
