Gray Mat­ters

The term gray mat­ter usu­ally evokes an image of the cor­tex, because that ’ s the part most vis­i­ble in pic­tures of the brain.  In fact, gray mat­ter makes up not only the cere­bral cor­tex but also the cen­tral por­tion of the spinal cord and areas called the cere­bel­lar cor­tex and the hip­pocam­pal cor­tex.  This dense tis­sue is packed full of neu­ronal cells, their den­drites (branch­ing, root — like end­ings), axon ter­mi­nals (the other end), and those sticky glial cells I men­tioned ear­lier. The cor­tex is the area of the brain where the actual pro­cess­ing of infor­ma­tion takes place.  Because of its rel­a­tive size and com­plex­ity, it ’ s easy to under­stand why it plays a key role in mem­ory, atten­tion, per­cep­tual aware­ness, thought, lan­guage, and consciousness.

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!)

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 »

You may have watched the new series Lie To Me, with Tim Roth, based on the work of Paul Ekman.

The sec­ond episode, which you can watch for free via Hulu.com Here, is pretty inter­est­ing, but the best part hap­pens in the begin­ning, so you only need to watch a few min­utes to learn why what are called “lie detec­tors” are noth­ing but biofeed­back sys­tems that mea­sure phys­i­o­log­i­cal anxiety.

Biofeed­back can be a very effec­tive train­ing tool for emo­tional self-regulation and stress man­age­ment, pre­cisely because it enables a faster feedback-based learn­ing loop. Indeed, we are see­ing a grow­ing num­ber of appli­ca­tions in the mar­ket, with names such as EmWave, StressEraser, RES­PeR­ATE, Jour­ney to the Wild Divine, and others.

Sim­ply, don’t believe the tech­nol­ogy is an effec­tive lie detector.

Car­o­line and I wrote an arti­cle on Paul Ekman’s work a cou­ple of years ago — let me repub­lish it now, given his work has made it all the way to main­stream TV!

Paul Ekman has con­ducted exten­sive research on iden­ti­fy­ing emo­tions through facial expres­sions. As part of that research, and as part of the power of dis­ci­pline and train­ing, he learned how to con­sciously manip­u­late 42 facial mus­cles, includ­ing many that in most of us are beyond our con­trol, and even awareness.

In the 60s and 70s when Ekman began look­ing into the uni­ver­sal­ity of facial expres­sions, all the major con­tem­po­rary social sci­en­tists, like Mar­garet Mead, believed that expres­sions were cul­tur­ally learned, not innate. He trav­eled all over the world with pic­tures of peo­ple mak­ing dis­tinct facial expres­sions and found peo­ple in cul­tures every­where, from mod­ern to stone age, agreed on the emo­tion behind the expres­sion. He then turned to Read the rest of this entry »

Learn­ing & the Brain is a con­fer­ence that gets marked on my cal­en­dar annu­ally because I always return home hav­ing either been exposed to new infor­ma­tion, or with a new per­spec­tive on an old topic. Last month’s con­fer­ence in Cam­bridge, MA, themed Using Emo­tions Research to Enhance Learn­ing & Achieve­ment, was no excep­tion. As with pre­vi­ous con­fer­ences, in addi­tion to the many keynote ses­sions, I focused on the adult learn­ing strand, since so much of my time is spent pro­vid­ing pro­fes­sional devel­op­ment for, and col­lab­o­rat­ing with adults. Here are five con­fer­ence cues as they relate to education.

1. CHALLENGE YOURSELF WITH NEW LEARNING

Aaron Nel­son stated that our mem­ory starts to decline between ages twenty-five and thirty, or to phrase it a bit more pos­i­tively, Sam Wang says our mem­ory peaks around age thirty. On the other end of the age spec­trum, accord­ing to Ken Kosik, there is unequiv­o­cal evi­dence that edu­ca­tion pro­tects against Alzheimer’s. Both Nel­son and Kosik men­tioned the the­ory of cog­ni­tive reserve, which trans­lates roughly to the more we learn, the more con­nec­tions we cre­ate, and there­fore the greater the neu­ronal buffer we have to draw upon as we age.

Elkhonon Gold­berg, at last April’s con­fer­ence, stated that “as one ages, the domain of the novel shrinks, and the domain of what is known grows”. He cau­tioned the audi­ence to beware of being on men­tal autopi­lot. Thus, the goal is not to sim­ply get bet­ter at doing more of the same. The type of learn­ing that makes a dif­fer­ence con­sists specif­i­cally of new, novel chal­lenges. The result of such engage­ment is that Read the rest of this entry »

Michael I. Pos­ner is a promi­nent sci­en­tist in the field of cog­ni­tive neu­ro­science. He is cur­rently an emer­i­tus pro­fes­sor of neu­ro­science at the Uni­ver­sity of Ore­gon (Depart­ment of Psy­chol­ogy, Insti­tute of Cog­ni­tive and Deci­sion Sci­ences). In August 2008, the Inter­na­tional Union of Psy­cho­log­i­cal Sci­ence made him the first recip­i­ent of the Dogan Prize “in recog­ni­tion of a con­tri­bu­tion that rep­re­sents a major advance in psy­chol­ogy by a scholar or team of schol­ars of high inter­na­tional reputation.”

Dr. Pos­ner, many thanks for your time today. I really enjoyed the James Arthur Lec­ture mono­graph on Evo­lu­tion and Devel­op­ment of Self-Regulation that you deliv­ered last year. Could you pro­vide a sum­mary of the research you presented?

I would empha­size that we human beings can reg­u­late our thoughts, emo­tions, and actions to a greater degree than other pri­mates. For exam­ple, we can choose to pass up an imme­di­ate reward for a larger, delayed reward.

We can plan ahead, resist dis­trac­tions, be goal-oriented. These human char­ac­ter­is­tics appear to depend upon what we often call “self-regulation.” What is excit­ing these days is that progress in neu­roimag­ing and in genet­ics make it pos­si­ble to think about self-regulation in terms of spe­cific brain-based networks.

Can you explain what self-regulation is?

All par­ents have seen this in their kids. Par­ents can see the remark­able trans­for­ma­tion as their chil­dren develop the abil­ity to reg­u­late emo­tions and to per­sist with goals in the face of dis­trac­tions. That abil­ity is usu­ally labeled ‚ self-regulation.

The other main area of your research is atten­tion. Can you explain the brain-basis for what we usu­ally call “attention”?

I have been inter­ested in how the atten­tion sys­tem devel­ops in infancy and early childhood.

One of our major find­ings, thanks to neu­roimag­ing, is that there is not one sin­gle “atten­tion”, but three sep­a­rate func­tions of atten­tion with three sep­a­rate under­ly­ing brain net­works: alert­ing, ori­ent­ing, and exec­u­tive atten­tion. Read the rest of this entry »

Daniel Gole­man requires no intro­duc­tion. Per­son­ally, of all his books I have read, the one I found most stim­u­lat­ing was Destruc­tive Emo­tions: A Sci­en­tific Dia­logue With the Dalai Lama, a superb overview of what emo­tions are and how we can put them to good use. He is now con­duct­ing a great series of audio inter­views includ­ing one with George Lucas on Edu­cat­ing Hearts and Minds: Rethink­ing Education.

We are hon­ored to bring you a guest post by Daniel Gole­man, thanks to our col­lab­o­ra­tion with Greater Good Mag­a­zine, a UC-Berkeley-based quar­terly mag­a­zine that high­lights ground break­ing sci­en­tific research into the roots of com­pas­sion and altru­ism. Enjoy!

My nat­ural rhythms are in cycle with the school cal­en­dar. Jan­u­ary 1st takes a back seat to my new year, which gets ush­ered in with the month of Sep­tem­ber when there is crisp­ness in the air that grad­u­ally shakes off the slower, more relaxed pace of summer.Conveniently, my career in teach­ing meshes with my nat­ural cycli­cal year. And as this year draws to a close, I am re-energized by the pace of sum­mer, know­ing that any­thing may pop in to my mind as I engage in activ­i­ties not directly related to school. But before that hap­pens, I’d like to reflect on this past year, in par­tic­u­lar as it was my first year of blog­ging about the brain.

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.
