Brain changes seen in cab­bies who take ‘The Knowl­edge (BBC Health):

“The struc­ture of a Lon­don taxi driver’s brain changes dur­ing the gru­el­ing process of learn­ing the quick­est way around the cap­i­tal, scans reveal. Dozens of trainee dri­vers had MRI scans before and after they acquired “The Knowl­edge”, mem­o­riz­ing hun­dreds of jour­neys and street names.

The Uni­ver­sity Col­lege Lon­don team, writ­ing in Cur­rent Biol­ogy, found brain parts linked to mem­ory grew big­ger. Read the rest of this entry »

How Exer­cise Ben­e­fits the Brain (NewYork Times):

“To learn more about how exer­cise affects the brain, sci­en­tists in Ire­land recently asked a group of seden­tary male col­lege stu­dents to take part in a mem­ory test fol­lowed by stren­u­ous exercise.

First, the young men watched a rapid-fire lineup of pho­tos with the faces and names of strangers. After a break, they tried to recall the names they had just seen as the pho­tos again zipped across a com­puter screen. Read the rest of this entry »

Stayin’ Alive

The Human Brain Likes to Be in Balance

For­tu­nately, the brain has some built — in safety sys­tems. Too much cor­ti­sol in the blood sig­nals the brain and adrenal glands to decrease cor­ti­sol pro­duc­tion. And under nor­mal con­di­tions, when the stress is over­come or brought under con­trol (by fight­ing, flee­ing, or turn­ing into an immo­bile statue, or by mas­ter­ing the threat), the hypo­thal­a­mus starts send­ing out the orders to stand down. Stop pro­duc­ing cor­ti­sol!  Event over!  Under con­tin­u­ous stress, how­ever, this feed­back sys­tem breaks down. The hypo­thal­a­mus keeps read­ing the stress as a threat, furtively send­ing mes­sages to the pitu­itary gland, which screams out to the adrenal glands to keep pump­ing out cor­ti­sol, which at this point begins to be neu­ro­toxic — poi­son to the brain.

I con­sider myself some­thing of a prospec­tive meditator—meaning that a seri­ous med­i­ta­tion prac­tice is always some­thing I’m about to start… next week. So for years, I’ve been mak­ing a men­tal note of new stud­ies show­ing that med­i­ta­tion can lit­er­ally change our brain struc­ture in ways that might boost con­cen­tra­tion, mem­ory, and pos­i­tive emotions.

The results seem entic­ing enough to make any­one drop into the full lotus position—until you read the fine print: Much of this research involves peo­ple who have med­i­tated for thou­sands of hours over many years; some of it zeroes in on Olympic-level med­i­ta­tors who have clocked 10,000 hours or more. Pretty daunting.

Well, a new study offers some hope—and makes the ben­e­fits of med­i­ta­tion seem within reach even for a novice like me. The study, pub­lished in Jan­u­ary in the jour­nal Psy­chi­a­try Research: Neu­roimag­ing, sug­gests that med­i­tat­ing for just 30 min­utes a day for eight weeks can increase the den­sity of gray mat­ter in brain regions asso­ci­ated with mem­ory, stress, and empa­thy.

My inter­est in the brain stems from want­ing to bet­ter under­stand both how to make school more palat­able for stu­dents, and pro­fes­sional devel­op­ment more mean­ing­ful for fac­ulty. To that end, I began my Neu­rons Fir­ing blog in April, 2007, have been doing a lot of read­ing, and been attend­ing work­shops and con­fer­ences, includ­ing Learn­ing & the Brain.

If you agree that our brains are designed for learn­ing, then as edu­ca­tors it is incum­bent upon us to be look­ing for ways to max­i­mize the learn­ing process for each of our stu­dents, as well as for our­selves. Some of what fol­lows is sim­ply com­mon sense, but I’ve learned that all of it has a sci­en­tific basis in our brains. Read the rest of this entry »

The July/ August 2009 issue of The Jour­nal on Active Aging includes my arti­cle Why We Need to Retool “Use It Or Lose It“

An excerpt:

“By now you have prob­a­bly heard about brain plas­tic­ity, the life­long capac­ity of the brain to change and rewire itself in response to the stim­u­la­tion of learn­ing and expe­ri­ence. The lat­est sci­en­tific research shows that spe­cific lifestyles and actions can improve the health and level of func­tion­ing of our brains, no mat­ter our age.

Of par­tic­u­lar impor­tance to main­tain­ing cog­ni­tive func­tion­ing through life are the hip­pocam­pus (deep inside the brain, part of what is called the lim­bic sys­tem), which plays a role in learn­ing and mem­ory; and the frontal lobes (behind your fore­head), which are key to main­tain­ing decision-making and auton­omy. Is there a way to phys­i­cally pro­tect these parts of the aging brain? Yes. But the right answer is far from “do one more cross­word puz­zle” or “do more X” (what­ever X is). The key is to add sig­nif­i­cantly dif­fer­ent activ­i­ties to ensure a flow of nov­elty, vari­ety and chal­lenge, com­bin­ing phys­i­cal and men­tal exer­cise while not ignor­ing fac­tors such as stress man­age­ment and bal­anced nutrition.

We need, in other words, to retool our under­stand­ing and prac­tice of “Use it or lose it.” We must focus on the impor­tance of get­ting out of our phys­i­cal and men­tal rou­tines and activ­i­ties to get the ben­e­fits of real exercise—physical and mental.”

This is a par­tial list of the lit­er­a­ture we reviewed dur­ing the research phase of our new book, The Sharp­Brains Guide to Brain Fit­ness.  We know many friends of Sharp­Brains are researchers, health­care pro­fes­sion­als, graduate/ Ph.D. stu­dents, who want have direct access to the ref­er­ences (per­haps PubMed should pro­mote itself as a never end­ing source of men­tal stim­u­la­tion?), so here you have this list, orga­nized by rel­e­vant chap­ter. Please note that the list below appears in the book — whose man­u­script we had to close in Jan­u­ary 2009.

We are excited to release our 2009 mar­ket report The State of the Brain Fit­ness Soft­ware Mar­ket 2009. To be for­mally released on May 4th but avail­able now for our clients and read­ers, this report aims to inform decision-makers at health­care, insur­ance, research, pub­lic pol­icy, invest­ment and tech­nol­ogy orga­ni­za­tions about impor­tant devel­op­ments in the brain fit­ness and cog­ni­tive health space.

2009 Mar­ket Report

The State of the Brain Fit­ness Soft­ware Mar­ket 2009: This new 150-page report finds sus­tained growth in the brain fit­ness soft­ware mar­ket (from $225m in 2007 to $265m in 2008) and promis­ing seeds for future growth, com­bined with increased con­fu­sion given aggres­sive mar­ket­ing claims and lack of edu­ca­tion and stan­dards. The report includes, for the first time, a Mar­ket & Research Momen­tum Matrix to cat­e­go­rize 21 key ven­dors, 10 Research Exec­u­tive Briefs writ­ten by 12 lead­ing sci­en­tists, and the com­plete results of our mar­ket sur­vey with 2,000+ respon­dents.

Upcom­ing Guide

This is one of the slides I cre­ated recently for my talks, and it seems to be get­ting the point across.

Your answer?

The follow-up ques­tion: is your job and life more sim­i­lar to the con­stant problem-solving and men­tal chal­lenge of the cab dri­ver, or to the rou­tine or the bus driver?
