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.

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.

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.

In 2005 the Amer­i­can Acad­emy of Pedi­atrics (AAP) began an ini­tia­tive to pro­mote an approach to care among its mem­bers in which “…the pedi­atric team works in part­ner­ship with a child and a child’s fam­ily to assure that all of the med­ical and non-medical needs of the patient are met.” A crit­i­cally impor­tant focus of this approach is the role of the fam­ily and child — as devel­op­men­tally appro­pri­ate — in the devel­op­ment of an over­all plan of care.

This shared decision-making approach is espe­cially impor­tant for con­di­tions like ADHD where there is not a sin­gle treat­ment that is the most appro­pri­ate and pre­ferred option for all patients. How­ever, Read the rest of this entry »

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!)

Although ADHD used to be con­sid­ered a dis­or­der of child­hood, follow-up stud­ies indi­cate that between 30% and 60% of chil­dren with ADHD con­tinue to expe­ri­ence symp­toms and impair­ment in adult­hood. And, even when ADHD symp­toms decline over time, many indi­vid­u­als con­tinue to expe­ri­ence sig­nif­i­cant impair­ment in impor­tant areas of functioning.

For exam­ple, chil­dren with ADHD have Read the rest of this entry »

The use of a vari­ety of brain train­ing inter­ven­tions is grow­ing in the area of men­tal health. Emerg­ing evi­dence sug­gests that in the near future tar­geted brain train­ing may even be used to pre­vent sub­stance abuse. For exam­ple, train­ing work­ing mem­ory may reduce sub­stance abusers’ dis­count­ing of long-term rewards and pun­ish­ments — such dis­count­ing is one of the rea­sons why peo­ple sus­cep­ti­ble to addic­tions do not ben­e­fit from tra­di­tional informational/ edu­ca­tional approaches to drug prevention.

Let’s explore some expand­ing appli­ca­tions of brain train­ing, and much more, in this lat­est edi­tion of the monthly Sharp­Brains eNewslet­ter.

Exer­cise and Over­weight Chil­dren: Aer­o­bic exer­cise can boost over­weight chil­dren exec­u­tive functions.

The Brain Grows With Prac­tice…: We know that when the brain mas­ters a new skill, tar­geted brain areas/ cir­cuits get enlarged. We now know that those areas and cir­cuits even­tu­ally shrink back to nor­mal, but per­for­mance gain can be maintained!

ADHD, or atten­tion deficit hyper­ac­tiv­ity dis­or­der, affects mil­lions of chil­dren and adults (up to 5% of chil­dren in the US).  More and more evi­dence sug­gests that brain train­ing may be key to help these indi­vid­u­als. With this in mind, we put together our most recent arti­cles on the topic to  a) help you bet­ter under­stand what is going in the brain of a per­son with ADHD, and b) pro­vide you with up-to-date infor­ma­tion on what can be done to fight the dis­or­der and improve the lives of peo­ple suf­fer­ing from it. We par­tic­u­larly thank Dr. Rabiner from Duke Uni­ver­sity for writ­ing many of these arti­cles.

What is ADHD?

What kind of atten­tion is involved in ADHD? ADHD may be con­sid­ered as a prob­lem in the will­ful con­trol of atten­tion as opposed to a pure deficit in the abil­ity to pay attention.

Although I no longer main­tain a clin­i­cal prac­tice, for years I worked with chil­dren with ADHD and their fam­i­lies. One thing I heard from many par­ents was that their child responded well to phys­i­cal exer­cise, that it helped their chil­dren burn off excess energy and main­tain a calmer and more focused state.

Indeed, evi­dence from sev­eral large-scale exper­i­men­tal stud­ies sug­gests that phys­i­cal activ­ity train­ing can have a pos­i­tive influ­ence on children’s cog­ni­tive func­tion­ing. Read the rest of this entry »
