A Neuroscientist’s Poignant Study of How We For­get Most Things in Life (The New Yorker):

Any study of mem­o­ry is, in the main, a study of its frailty. In “Remem­ber,” an engross­ing sur­vey of the lat­est research, Lisa Gen­o­va explains that a healthy brain quick­ly for­gets most of what pass­es into con­scious aware­ness. The frag­ments of expe­ri­ence that do get encod­ed into long-term mem­o­ry are then sub­ject to “cre­ative edit­ing.” To remem­ber an event is to reimag­ine it; in the reimag­in­ing, we inad­ver­tent­ly intro­duce new infor­ma­tion, often col­ored by our cur­rent emo­tion­al state. A dream, a sug­ges­tion, and even the mere pas­sage of time can warp a mem­o­ry. It is sober­ing to real­ize that three out of four pris­on­ers who are lat­er exon­er­at­ed through DNA evi­dence were ini­tial­ly con­vict­ed on the basis of eye­wit­ness tes­ti­mo­ny. “You can be 100 per­cent con­fi­dent in your vivid mem­o­ry,” Gen­o­va writes, “and still be 100 per­cent wrong.” [Read more…] about Neu­ro­sci­en­tist Lisa Gen­o­va, author of the beau­ti­ful nov­el Still Alice, releas­es non-fic­tion book on Memory

Fun brain teaser to test your cognitive skills during International Brain Teaser Month

Mem­o­ry relies most­ly on the tem­po­ral lobes (see green area) and also the frontal lobes (red), Temporal lobe Frontal Lobeso those are the areas that will get some good neu­ronal acti­va­tion when read­ers raised in the US try to remem­ber the miss­ing words in the Amer­i­can proverbs below.

Now, if you were raised out­side the US and are not famil­iar with those proverbs you will have to use your rea­son­ing skills more than your mem­o­ry skills — In that case, frontal lobe acti­va­tion will be wider and more intense.

Con­verse­ly, if you were raised in the US you will find the inter­na­tion­al proverbs below to be more chal­leng­ing. You will not be able to remem­ber them, as you prob­a­bly nev­er learned them, but you should be able to fig­ure them out for extra frontal lobe, cog­ni­tive exercise.

Here’s the task: Guess the miss­ing words of each US and inter­na­tion­al proverb below. Get a pen and piece of paper and write your answers before you check the solutions 🙂

Jobs with low physical stress and good working conditions linked to larger hippocampus and better memory

by

CSU study links phys­i­cal stress on the job with brain and mem­o­ry decline in old­er age (press release):

A new study out of Col­orado State Uni­ver­si­ty has found that phys­i­cal stress in one’s job may be asso­ci­at­ed with faster brain aging and poor­er memory.

Aga Burzyn­s­ka, an assis­tant pro­fes­sor in the Depart­ment of Human Devel­op­ment and Fam­i­ly Stud­ies, and her research team con­nect­ed occu­pa­tion­al sur­vey respons­es with brain-imag­ing data from 99 cog­ni­tive­ly nor­mal old­er adults, age 60 to 79. They found that those who report­ed high lev­els of phys­i­cal stress in their most recent job had small­er vol­umes in the hip­pocam­pus and per­formed poor­er on mem­o­ry tasks. The hip­pocam­pus is the part of the brain that is crit­i­cal for mem­o­ry and is affect­ed in both nor­mal aging and in dementia.

On World Health Day 2020, let’s discuss the stress response and the General Adaptation Syndrome (2/3)

by

The hypothalamus–pituitary–adrenal (HPA) axis acts to release cor­ti­sol into the blood stream, as cor­ti­sol calls the body into action to com­bat stress. When high amounts of cor­ti­sol inter­act with the hypo­thal­a­mus, the HPA axis will slow down its activ­i­ty. The amyg­dala detects stress, while the pre­frontal cor­tex reg­u­lates our reac­tions to stress. Source: Bezdek K and Telz­er E (2017) Have No Fear, the Brain is Here!

[Editor’s note: Con­tin­ued from yes­ter­day’s Explor­ing the human brain and how it responds to stress (1/3)]

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 [Read more…] about On World Health Day 2020, let’s dis­cuss the stress response and the Gen­er­al Adap­ta­tion Syn­drome (2/3)

Neuroscience tips about gratitude, aging, pain and the brain: An interview with Dr. Daniel Levitin

About 13 years ago, I watched my very vital moth­er die a slow death from Lewy-Body demen­tia. For me, it was a wake­up call. If there were any­thing I could do to stay healthy myself—to avoid the slow decline of an aging brain—I want­ed to do it. But what real­ly helps us stay sharp longer? And how can we sep­a­rate fad ideas from sol­id, evi­dence-based advice around aging?

Ready for a Hap­py New Year  and Hap­py New Decade?

Here’s a spe­cial edi­tion of the Sharp­Brains month­ly e‑newsletter fea­tur­ing the lat­est on brain health and men­tal well-being — we hope you enjoy these tips and advice about what to do, and what not to, to pro­mote brain well­ness in 2020 and beyond:

Prac­tice Breath­ing & Com­pas­sion: Three evi­dence-based ways to devel­op a resilient mind

… and a Sport you love: Play sports (smart­ly) for a qui­eter brain

Chal­lenge your friends, often: For bet­ter mem­o­ry and think­ing skills at age 70, play cards and board games from age 11

… for exam­ple by solv­ing big prob­lems togeth­er: Mind­strong Health recruits slew of Sil­i­con Val­ley talent

When in trou­ble, con­sid­er ther­a­py before meds: To treat depres­sion, ther­a­py alone works bet­ter than ther­a­py com­bined with antidepressants

… your might even be able to access it pri­vate­ly, online: First Dig­i­tal Health For­mu­la­ry by Express Scripts includes CBT-based pro­grams to treat depres­sion, anx­i­ety and insomnia

Final­ly, beware “brain-boost­ing” sup­ple­ments, and don’t jump on direct-to-con­sumer tran­scra­nial direct cur­rent stim­u­la­tion (tDCS) unless you under­stand Pros and Cons

… but always keep your mind open to awe and to new ways to tease your brain, see the world around us and even shape it!

 

Wishing you a happy, healthy and prosperous New Year and New Decade,
