Worry is like a rock­ing chair. It gives you some­thing to do, but it gets you nowhere.
— Erma Bombeck

The brain is the con­trol cen­ter for all of our thoughts, actions, atti­tudes, and emo­tions. It ’ s the pilot­house on the river­boat of our lives. It’s Mis­sion Con­trol for all of our fl ights into space or time. It ’ s the air traffic con­troller that helps us nav­i­gate and reroute our paths based on incom­ing and out­go­ing infor­ma­tion and how we’re feel­ing about it at the time. It’s the John Williams of our per­sonal sym­phony. It ’ s the Mother Ship to our Starfleet; it’s . . . (Uh, sorry, I got car­ried away there, but I think you get my point!)

Train­ing the brain is pos­si­ble because of neu­ro­plas­tic­ity. Our daily expe­ri­ences can trig­ger neu­ro­plas­tic changes in the brain, such as the growth of new brain cells (neu­rons) and new con­nec­tions (synapses) between neu­rons. Plas­tic­ity is observed at all ages but is at its peak dur­ing brain devel­op­ment, as a baby and then a child learns basic knowl­edge and skills nec­es­sary to sur­vive. We should thus expect that the brain of a baby could be eas­ily trained. This is what Wass and his col­leagues recently demon­strated in a new study with 11-month-old babies.

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 »

These fan­tas­tic pic­tures by Carl Schoonover in “Por­traits of the Mind: Visu­al­iz­ing the Brain from Antiq­uity to the 21st Cen­tury” will have 2 effects on your brain: 1) stim­u­late the neu­rons in your occip­i­tal lobes (as you know, the part at the back of your  brain that is devoted to vision) and 2) acti­vate your rea­son­ing skills as you reflect on what the mind is…

We’ve all been there: obsess­ing over a faux pas we com­mit­ted at a party, infu­ri­ated by an unkind word from a col­league, rumi­nat­ing over a tough break-up with a spouse or friend. We suf­fer some misfortune—big or small, real or imagined—and the pain or humil­i­a­tion sticks with us for hours, days, or even years afterward.

“The mind is like Vel­cro for neg­a­tive expe­ri­ences,” psy­chol­o­gist Rick Han­son is fond of say­ing, “and Teflon for pos­i­tive ones.”

But it doesn’t have to be this way. Draw­ing on some of the lat­est find­ings from neu­ro­science, Han­son has spent years explor­ing how we can over­come our brain’s nat­ural “neg­a­tiv­ity bias” and learn to inter­nal­ize pos­i­tive expe­ri­ences more deeply—while min­i­miz­ing the harm­ful phys­i­cal and psy­cho­log­i­cal effects of dwelling on the negative.

For years, research has shown that, over time, our expe­ri­ences lit­er­ally reshape our brains and can change our ner­vous sys­tems, for bet­ter or worse. Now, neu­ro­sci­en­tists and psy­chol­o­gists like Han­son are zero­ing in on how we can take advan­tage of this “plas­tic­ity” of the brain to cul­ti­vate and sus­tain pos­i­tive emotions.

In his recent book, the best-selling Buddha’s Brain: The Prac­ti­cal Neu­ro­science of Hap­pi­ness, Love, and Wis­dom, Han­son describes spe­cific prac­tices that can pro­mote last­ing joy, equa­nim­ity, and compassion—and backs it all up with sound science.

Han­son recently spoke with host Michael Bergeisen about some of these very prac­ti­cal, research-based steps we can all take to rewire our brains for last­ing hap­pi­ness. Below we present a con­densed ver­sion of the dis­cus­sion. Read the rest of this entry »

Have you already read The Sharp­Brains Guide to Brain Fit­ness?

Let’s see…

1. Pick the only part of your body that does not con­tain fat:

a. Arm
b. Thigh
c. Brain
d. None

Answer: d) Fats are also present in the brain: in neu­rons’ mem­branes to keep them flex­i­ble. These fats are the omega 3 and omega 6 fatty acids mol­e­cules. (Page 32 of the book)

2. Pick the only food prod­uct that doesn’t con­tain Omega-3 fatty acids

a. Tuna
b. Wal­nut
c. Kiwi
d. Jelly Beans

Answer: d) Fatty acids can be found in cold-water fish (such as mack­erel, her­ring, salmon, and tuna), kiwi, and wal­nuts. (Page 33)

3. Pick the only food prod­uct that doesn’t con­tain antioxidants

a. Olive oil
b. Milk
c. Nuts
d. Berries

Answer: b) Antiox­i­dants can be found in veg­etable oils, nuts, green leafy veg­eta­bles (e.g., spinach), cit­rus fruit, and berries. (Page 33)

4. Chronic Stress cannot:

a. Pre­vent you from being cre­ative
b. Kill brain cells
c. Pre­vent you from sleep­ing
d. Kill liver cells

Answer: d) Pro­longed expo­sure to adrenal steroid hor­mones like cor­ti­sol, which is released into the blood stream when we are stressed, can lead to cell death and block the for­ma­tion of new neu­rons. (Page 35)

5. What type of phys­i­cal exer­cise is the best for your brain health?

a. Weight lift­ing
b. Aer­o­bic exer­cises
c. Flex­i­bil­ity exer­cises Read the rest of this entry »

In a recently pub­lished sci­en­tific study (see Hall C, et al “Cog­ni­tive activ­i­ties delay onset of mem­ory decline in per­sons who develop demen­tia” Neu­rol­ogy 2009; 73: 356–361), Hall and col­leagues exam­ined how edu­ca­tion and stim­u­lat­ing activ­i­ties may inter­act to con­tribute to cog­ni­tive reserve. The study involved 488 ini­tially healthy peo­ple, aver­age age 79, who enrolled in the Bronx Aging Study between 1980 and 1983. These indi­vid­u­als were fol­lowed for 5 years with assess­ments every 12 to 18 months (start­ing in 1980). At the start of the study, all par­tic­i­pants were asked how many cog­ni­tive activ­i­ties (read­ing, writ­ing, cross­word puz­zles, board or card games, group dis­cus­sions, or play­ing music) they par­tic­i­pated in and for how many days a week. Researchers were able to eval­u­ate the impact of self-reported par­tic­i­pa­tion these activ­i­ties on the onset of accel­er­ated mem­ory decline in 101 indi­vid­u­als who devel­oped demen­tia dur­ing the study.

Results showed that for every “activ­ity day” (par­tic­i­pa­tion in one activ­ity for one day a week) the sub­jects engaged in, they delayed for about two months the onset of rapid mem­ory loss asso­ci­ated with demen­tia. Inter­est­ingly, the pos­i­tive effect of brain-stimulating activ­i­ties in this study appeared to be inde­pen­dent of a person’s level of education.

This is great news as it sug­gests that it is never too late to try to build up brain reserve. The more brain stim­u­lat­ing activ­i­ties one does and the more often, the bet­ter for a stronger cog­ni­tive reserve.

The cog­ni­tive reserve hypoth­e­sis sug­gests that indi­vid­u­als with more cog­ni­tive reserve can expe­ri­ence more Alzheimer’s dis­ease pathol­ogy in the brain (more plaques and tan­gles) with­out devel­op­ing Alzheimer’s dis­ease symptoms.

How does that work? Sci­en­tists are not sure but two pos­si­bil­i­ties are con­sid­ered.
1. One is that more cog­ni­tive reserve means more brain reserve, that is more neu­rons and con­nec­tions between neu­rons.
2. Another pos­si­bil­ity is that more cog­ni­tive reserve means more com­pen­satory processes (see my pre­vi­ous post “Edu­ca­tion builds Cog­ni­tive Reserve for Alzheimers Dis­ease Pro­tec­tion” for more details.)

Now, one may won­der about the dif­fer­ence types of men­tal stim­u­la­tion avail­able, includ­ing not only puz­zles and such, but struc­tured activ­i­ties such as brain fit­ness soft­ware and med­i­ta­tion. Do we exer­cise our brain every time we think about some­thing? What can one do to exer­cise one’s brain in ways that enhance capac­ity? Does aer­o­bic fit­ness train­ing also exer­cise one’s brain? What types of method­olo­gies and prod­ucts are avail­able? Do they “work”? Are all the same?

Those are the types of ques­tions we wanted to address in the book The Sharp­Brains Guide To Brain Fit­ness (avail­able via Amazon.com). We are proud of the recog­ni­tion the book has started to obtain, includ­ing endorse­ments by lead­ing scientists:

“The Sharp­Brains Guide to Brain Fit­ness is the only book that I know of that seam­lessly inte­grates lat­est infor­ma­tion about cog­ni­tive health across the lifes­pan, with inter­views with active researchers exam­in­ing cog­ni­tive main­te­nance and enhance­ment, along with reviews of com­mer­cial prod­ucts tar­geted to cog­ni­tive enhance­ment. The book should be very use­ful to any­one inter­ested in brain care, both health care pro­fes­sion­als and the pub­lic at large”.
— Arthur Kramer, Pro­fes­sor of Psy­chol­ogy at Uni­ver­sity of Illinois

In our 2008 mar­ket report we offered Top 10 Brain Train­ing Future Trends, includ­ing:

“2. Phys­i­cal and men­tal exer­cise will be bet­ter inte­grated. Phys­i­cal exer­cise has been shown to increase the rate of neu­ro­ge­n­e­sis, whereas men­tal exer­cise helps ensure the sur­vival of any newly cre­ated neu­rons. Today both activ­i­ties usu­ally take place in very dif­fer­ent set­tings: the for­mer, in health clubs, the later, in uni­ver­si­ties. We pre­dict that the bor­ders between them will become more dif­fuse. Expect new pro­grams such as brain fit­ness pod­casts that allow us to train work­ing mem­ory as we jog or exer­cise bikes with built-in brain games.”

We all have heard “Use It or Lose It”. Now, what is “It”? how does “it” work? why is “it” our best (and too often unrec­og­nized) friend?

The Soci­ety for Neu­ro­science (SfN) has just released a user-friendly pub­li­ca­tion titled Neu­ro­science Core Con­cepts, aimed at help­ing edu­ca­tors and the gen­eral pub­lic learn more about the brain.

Descrip­tion: “Neu­ro­science Core Con­cepts offer fun­da­men­tal prin­ci­ples that one should know about the brain and ner­vous sys­tem, the most com­plex liv­ing struc­ture known in the uni­verse. They are a prac­ti­cal resource about:

• - How your brain works and how it is formed.
• - How it guides you through the changes in life.
• - Why it is impor­tant to increase under­stand­ing of the brain.”

I first dis­cov­ered Nor­man Doidge’s book, The Brain That Changes Itself, in a May, 2007 review in the New York Times. Intrigued, but caught up in myr­iad end-of-school-year respon­si­bil­i­ties, the book was put out of my mind until later that sum­mer, when our schools learn­ing spe­cial­ist emailed to say she had just fin­ished a fas­ci­nat­ing book. The Brain That Changes Itself: Stores of Per­sonal Tri­umph from the Fron­tiers of Brain Sci­ence, is a com­pelling col­lec­tion of tales about the amaz­ing abil­i­ties of the brain to rewire, read­just and relearn after hav­ing a slice of itself ren­dered dys­func­tional. The first seven chap­ters cap­ti­vated me for their per­sonal sto­ries; the final four chap­ters for the sci­ence and philosophy.

Part of what makes Doidge’s writ­ing so acces­si­ble is he tells sto­ries, and his sto­ries just hap­pen to incor­po­rate brain sci­ence. As a result, his book is easy to digest. The neu­ro­science behind Doidge’s book involves neu­ro­plas­tic­ity, which is the brain’s abil­ity to rewire itself. This means that the brain is our intel­li­gence  is not some­thing fixed in con­crete but rather a chang­ing, learn­ing entity. On the face of it, this con­cept should not sound unusual, for it is what hap­pens to indi­vid­u­als all the time as we go about the learn­ing process, from infancy onwards.

What sep­a­rates the sto­ries in this book from daily learn­ing is that Read the rest of this entry »
