Very sig­nif­i­cant find­ings reported today. Keep­ing brain sharp may ward off Alzheimer’s pro­tein (Reuters):

“Peo­ple who chal­lenge their brains through­out their life­times — through read­ing, writ­ing and play­ing games — are less likely to develop pro­tein deposits in the brain linked with Alzheimer’s, researchers said on Mon­day.” Read the rest of this entry »

Tak­ing a posi­tion in any argument—large or small—is slip­pery busi­ness for our brains. We can have every inten­tion of hon­estly pur­su­ing an answer, yet still fool our­selves into think­ing our method is objec­tive when it is, in fact, any­thing but. Cog­ni­tive sci­ence has helped deci­pher this enigma with research on the the­o­ret­i­cal men­tal struc­tures our brains use to orga­nize infor­ma­tion, called schemata.

TO FIGHT, FLEE, OR FREEZE — THAT IS THE QUESTION

With a bet­ter under­stand­ing of the neu­ro­bi­ol­ogy of stress, the LD — ADHD — stress con­nec­tion becomes clear.  Stu­dents with learn­ing dis­abil­i­ties or ADHD, con­fronted with the stress cre­ated by expo­sure to tasks that are in real­ity or in their per­cep­tion too dif­fi­cult (and thus threat­en­ing), exhibit the pro­tec­tive behav­ior of any organ­ism under extreme stress:  They fight, they flee, or they freeze. When these kids don’t under­stand why they can’t do what other kids can do (mas­ter the stres­sor), and they can’t see any way to get out of a sit­u­a­tion that won’t go away, they begin to shut down.

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.

THE STRESS RESPONSE EXPLAINED

Stress was put on the map, so to speak, by a Hun­gar­ian — born Cana­dian endocri­nol­o­gist named Hans Hugo Bruno Selye (ZEL — yeh) in 1950, when he pre­sented his research on rats at the annual con­ven­tion of the Amer­i­can Psy­cho­log­i­cal Asso­ci­a­tion. To explain the impact of stress, Selye pro­posed some­thing he called the Gen­eral Adap­ta­tion Syn­drome (GAS), which he said had three com­po­nents. Accord­ing to Selye, when an organ­ism expe­ri­ences some novel or threat­en­ing stim­u­lus it responds with an alarm reac­tion. This is fol­lowed by what Selye referred to as the recov­ery or resis­tance stage, a period of time dur­ing which the brain repairs itself and stores the energy it will need to deal with the next stress­ful event.

Fun arti­cle by Daniel Kah­ne­man based on his new book,Think­ing, Fast and Slow.

How cog­ni­tive illu­sions blind us to rea­son (The Guardian):

Why do Wall Street traders have such faith in their pow­ers of pre­dic­tion, when their suc­cess is largely down to chance? Daniel Kah­ne­man explains.

- “Look­ing back, the most strik­ing part of the story is that our knowl­edge of the gen­eral rule that we could not pre­dict had no effect on our con­fi­dence in indi­vid­ual cases. We were reluc­tant to infer the par­tic­u­lar from the gen­eral. Sub­jec­tive con­fi­dence in a judg­ment is not a rea­soned eval­u­a­tion of the prob­a­bil­ity that this judg­ment is cor­rect. Con­fi­dence is a feel­ing, which reflects the coher­ence of the infor­ma­tion and the cog­ni­tive ease of pro­cess­ing it. It is wise to take admis­sions of uncer­tainty seri­ously, but dec­la­ra­tions of high con­fi­dence mainly tell you that an indi­vid­ual has con­structed a coher­ent story in his mind, not nec­es­sar­ily that the story is true.” …

- “The sub­jec­tive expe­ri­ence of traders is that they are mak­ing sen­si­ble edu­cated guesses in a sit­u­a­tion of great uncer­tainty. In highly effi­cient mar­kets, how­ever, edu­cated guesses are no more accu­rate than blind guesses.”

Under­stand­ing the Human Brain and How It Responds to Stress

The Lit­tle Brain Down Under

The tour con­tin­ues … Sit­ting under the occip­i­tal and tem­po­ral lobes of the brain is the cere­bel­lum. It’s about the size of a child’s fist. Because it looks like a sep­a­rate brain­like struc­ture attached to the under­side of the cor­tex, the cere­bel­lum is some­times referred to as the “ lit­tle brain. ” It’s con­nected to the brain stem, which in turn con­nects the brain to the spinal cord. The cere­bel­lum used to be rel­e­gated to the very sim­ple role of help­ing us main­tain bal­ance when we walk or run, but mod­ern neu­ro­science has found that the cere­bel­lum plays a much larger and more impor­tant role than that.
