A few days ago we pub­lished the first and sec­ond install­ments of this Peace Among Pri­mates series, by neu­ro­sci­en­tist Robert Sapol­sky. Today we pub­lish the third and final one.

Peace Among Pri­mates (Part 3)

Any­one who says peace is not part of human nature knows too lit­tle about pri­mates, includ­ing ourselves.

Brain Fit­ness News and Events

Upcom­ing Events: I will be speak­ing at five Health, Edu­ca­tion and Gam­ing events over the next cou­ple of months to intro­duce find­ings from our recent mar­ket report. Please intro­duce your­self if you attend any of these events.

Pre­vent­ing Mem­ory Loss-Special Issue: Con­gres­sional Quar­terly Researcher, one of the main pub­li­ca­tions on Capi­tol Hill, pub­lished an impres­sive 24-page spe­cial issue titled Pre­vent­ing Mem­ory Loss.

A few days ago we pub­lished the first install­ment of this Peace Among Pri­mates series, by neu­ro­sci­en­tist Robert Sapol­sky. Today we pub­lish the sec­ond install­ment. Next Sat­ur­day, April 19th, you can come back and read the third and final part in the series.

In the early 1980s, “For­est Troop,” a group of savanna baboons I had been studying—virtually liv­ing with—for years, was going about its busi­ness in a national park in Kenya when a neigh­bor­ing baboon group had a stroke of luck: Read the rest of this entry »

One of the most orig­i­nal minds we have ever encoun­tered is that of Robert Sapol­sky, the Stanford-based pri­mate (plus neu­ro­sci­en­tist, pri­ma­tol­o­gist, author of A Primate’s Mem­oir, and more). We highly rec­om­mend most of his books. Above all, for any­one inter­ested in brain health, this is a must read (and very fun): Why Zebras Don’t Get Ulcers: An Updated Guide To Stress, Stress Related Dis­eases, and Cop­ing.

We are hon­ored to bring you a guest Arti­cle Series by Robert Sapol­sky, 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 this first install­ment, out of three. Very timely given the so-called “war on ter­ror”. Come back on Sat­ur­day April 12th for the sec­ond one, or sub­scribe to our RSS or newslet­ter to keep in the loop.

Peace Among Pri­mates

Any­one who says peace is not part of human nature knows too lit­tle about pri­mates, includ­ing ourselves.

–By Robert M. Sapolsky

It used to be thought that humans were the only sav­agely vio­lent pri­mate. “We are the only species that kills its own,” nar­ra­tors intoned por­ten­tously in nature films sev­eral decades ago. That view fell by the way­side in the 1960s as it became clear that some other pri­mates kill their fel­lows aplenty. Males kill; females kill. Some use their tool­mak­ing skills to fash­ion big­ger and bet­ter cud­gels. Other pri­mates even engage in what can only be called warfare—organized, proac­tive group vio­lence directed at other populations.

Yet as field stud­ies of pri­mates expanded, what became most strik­ing was the vari­a­tion in social prac­tices across species. Yes, some pri­mate species have lives filled with vio­lence, fre­quent and var­ied. But life among oth­ers is filled with com­mu­ni­tar­i­an­ism, egal­i­tar­i­an­ism, and coop­er­a­tive child rear­ing. Read the rest of this entry »

Below you have a very insight­ful arti­cle on stress by one of our new Expert Con­trib­u­tors, Gre­gory Kel­let, a researcher at UCSF. Enjoy! (Credit for Pic of Vic­to­ria Crater in Mars: Mars Recon­nais­sance Orbiter, via Wikipedia).

“My brain is fried, toast, fraz­zled, burnt out. How many times have you said or heard one ver­sion or another of these state­ments. Most of us think we are being fig­u­ra­tive when we utter such phrases, but research shows that the bio­log­i­cal con­se­quences of sus­tained high lev­els of stress may have us being more accu­rate than we would like to think.

Crash Course on Stress

Our bod­ies are a com­plex bal­anc­ing act between sys­tems work­ing full time to keep us alive and well. This bal­anc­ing act is con­stantly adapt­ing to the myr­iad of changes occur­ring every sec­ond within our­selves and our envi­ron­ments. When it gets dark our pupils dilate, when we get hot we sweat, when we smell food we sali­vate, and so forth. This con­stant bal­anc­ing act main­tains a range of sta­bil­ity in the body via change; and is often referred to as allosta­sis. Any change which threat­ens this bal­ance can be referred to as allo­sta­tic load or stress.

Allo­sta­tic load/stress is part of being alive. For exam­ple just by get­ting up in the morn­ing, we all expe­ri­ence a very impor­tant need to increase our heart rate and blood pres­sure in order to feed our newly ele­vated brain. Although usu­ally man­age­able, this is a change which the body needs to adapt to and, by our def­i­n­i­tion, a stressor.

Stress is only a prob­lem when this allo­sta­tic load becomes over­load. When change is exces­sive or Read the rest of this entry »

As you may have noticed, we just changed a few things in our site, includ­ing prepar­ing a more solid Resources sec­tion. Please take a look at the nav­i­ga­tion bar at the top.

One of the new pages, that we will update often, is an expanded Books page. Here are the books that we are rec­om­mend­ing now.

Fas­ci­nat­ing books on neu­ro­plas­tic­ity (the abil­ity of the brain to rewire itself through experience):

Train Your Mind, Change Your Brain: How a New Sci­ence Reveals Our Extra­or­di­nary Poten­tial to Trans­form Our­selves — by Sharon Begley.

We had a very fun ses­sion titled Teach­ing Brain Fit­ness in Your Com­mu­nity at an Amer­i­can Soci­ety on Aging (ASA) con­fer­ence for health pro­fes­sion­als a cou­ple of weeks ago. Full house, with over 60 atten­dants and very good par­tic­i­pa­tion, show­ing great inter­est in the topic. I can’t wait to see the evaluations.

These are some of the resources I promised as a follow-up, which can be use­ful to every­one inter­ested in our field:

Here is ques­tion 18 of 25 from Brain Fit­ness 101: Answers to Your Top 25 Ques­tions.

Ques­tion:
Is phys­i­cal fit­ness impor­tant to your brain fitness?

Key Points:

• Exer­cise improves learn­ing through increased blood sup­ply and growth hormones.
• Exer­cise is an anti-depressant by reduc­ing stress and pro­mot­ing neurogenesis.
• Exer­cise pro­tects the brain from dam­age and dis­ease, as well as speed­ing the recovery.
• Exer­cise ben­e­fits you the most when you start young.

Here is ques­tion 15 of 25 from Brain Fit­ness 101: Answers to Your Top 25 Ques­tions.

Ques­tion:
I don’t want to ever retire. What can I do to remain sharp?

Key Points:

• Pro­vide your brain with reg­u­lar men­tal stim­u­la­tion that is novel and challenging.
• Main­tain your social net­work for both stim­u­la­tion and stress reduction.

“Research has shown that con­trary to pop­u­lar belief, the brain is con­stantly under­go­ing neu­ro­ge­n­e­sis, the devel­op­ment of new neu­rons and den­drites,” said Dr. Elkhonon Gold­berg, Clin­i­cal Pro­fes­sor of Neu­rol­ogy at New York Uni­ver­sity School of Med­i­cine. “Learn­ing and tar­geted men­tal exer­cise pro­motes neu­ro­ge­n­e­sis – the cre­ation of new neu­rons – just as mus­cle growth is pro­moted through phys­i­cal exercise.”
