As our final arti­cle for 2011, let us repur­pose one of Sharp­Brains’ most pop­u­lar blog posts since 2006. It may give you a few point­ers to sharpen those New Years Res­o­lu­tions. Let’s sum­ma­rize some lifestyle guide­lines we can all fol­low to enhance and main­tain a sharp brain through life...

1. Learn what is the “It” in “Use It or Lose It”. A basic under­stand­ing will serve you well to appre­ci­ate your brain’s beauty as a liv­ing and constantly-developing dense for­est with bil­lions of neu­rons and synapses.
2. Take care of your nutri­tion. Did you know that the brain only weighs 2% of body mass but con­sumes over 20% of the oxy­gen and nutri­ents we intake? As a gen­eral rule, you don’t need expen­sive ultra-sophisticated nutri­tional sup­ple­ments, just make sure you don’t stuff your­self with the “bad stuff”.
3. Remem­ber that the brain is part of the body. Things that exer­cise your body can also help sharpen your brain: phys­i­cal exer­cise enhances neurogenesis.
4. Prac­tice pos­i­tive, future-oriented thoughts until they become your default mind­set and you Read the rest of this entry »

Given many of us are start­ing to pre­pare New Year Res­o­lu­tions, let’s revisit one of Sharp­Brains’ most popular-ever arti­cles that can help us all refine our Brain Fit­ness Res­o­lu­tions…

The Ten Habits of Highly Effec­tive Brains

Today we have the plea­sure to have Dr. Pas­cale Mich­e­lon, one of our new Expert Con­trib­u­tors, write her first arti­cle here. Enjoy, and please com­ment so we hear your thoughts and engage in a nice conversation.

(Btw, if you notice some sim­i­lar­ity between the col­ors in the fMRI scan below and the look & feel of this site…well, the rea­son is that those orange-grey fMRI col­ors were our inspi­ra­tion! the orange color denotes the most brain activation).

You have prob­a­bly heard about CAT and MRI scans (pro­duced thanks to machines like the one to the top right). So you know that these are tech­niques that doc­tors and sci­en­tists use to look inside the brain.

You have prob­a­bly also heard about brain fit­ness and how impor­tant it is to keep a healthy brain to be pro­tected against age-related and disease-related brain damages.

The ques­tion we ask here is the fol­low­ing: Can we use brain scans to eval­u­ate how fit the brain is? Before we try to answer this ques­tion let’s start with the basics and try to under­stand how brain scans work.

Brain imag­ing, also called neu­roimag­ing, allows one to Read the rest of this entry »

Let’s review some good lifestyle options we can fol­low to main­tain, and improve, our vibrant brains.

1. Learn what is the “It” in “Use It or Lose It”. A basic under­stand­ing will serve you well to appre­ci­ate your brain’s beauty as a liv­ing and constantly-developing dense for­est with bil­lions of neu­rons and synapses.
2. Take care of your nutri­tion. Did you know that the brain only weighs 2% of body mass but con­sumes over 20% of the oxy­gen and nutri­ents we intake? As a gen­eral rule, you don’t need expen­sive ultra-sophisticated nutri­tional sup­ple­ments, just make sure you don’t stuff your­self with the “bad stuff”.
3. Remem­ber that the brain is part of the body. Things that exer­cise your body can also help sharpen your brain: phys­i­cal exer­cise enhances neurogenesis.
4. Prac­tice pos­i­tive, future-oriented thoughts until they become your default mind­set and you look for­ward to every new day in a con­struc­tive way. Stress and anx­i­ety, no mat­ter whether induced by exter­nal events or by your own thoughts, actu­ally kills neu­rons and pre­vent the cre­ation of new ones. You can think of chronic stress as the oppo­site of exer­cise: it pre­vents the cre­ation of new neurons.
5. Thrive on Learn­ing and Men­tal Chal­lenges. The point of hav­ing a brain is pre­cisely to learn and to adapt to chal­leng­ing new envi­ron­ments. Once new neu­rons appear in your brain, where they stay in your brain and how long they sur­vive depends on how you use them. “Use It or Lose It” does not mean “do cross­word puz­zle num­ber 1,234,567″. It means, “chal­lenge your brain often with fun­da­men­tally new activities”.
6. We are (as far as we know) the only self-directed organ­isms in this planet. Aim high. Once you grad­u­ate from col­lege, keep learn­ing. The brain keeps devel­op­ing, no mat­ter your age, and it reflects what you do with it.
7. Explore, travel. Adapt­ing to new loca­tions forces you to pay more atten­tion to your envi­ron­ment. Make new deci­sions, use your brain.
8. Don’t Out­source Your Brain. Not to media per­son­al­i­ties, not to politi­cians, not to your smart neigh­bour… Make your own deci­sions, and mis­takes. And learn from them. That way, you are train­ing your brain, not your neighbour’s.
9. Develop and main­tain stim­u­lat­ing friend­ships. We are “social ani­mals”, and need social inter­ac­tion. Which, by the way, is why ‘Baby Ein­stein’ has been shown not to be the panacea for chil­dren development.
10. Laugh. Often. Espe­cially to cog­ni­tively com­plex humor, full of twists and sur­prises. Bet­ter, try to become the next Jon Stewart

Now, remem­ber that what counts is not read­ing this article-or any other-, but prac­tic­ing a bit every day until small steps snow­ball into unstop­pable, inter­nal­ized habits…so, pick your next bat­tle and try to start improv­ing at least one of these 10 habits today. Revisit the habit above that really grabbed your atten­tion, click on the link to learn more, and make a deci­sion to try some­thing dif­fer­ent today!

I was exposed to a fun brain exer­cise on Mon­day: attend my first-ever live TV pro­gram, be ready for 3 very pre­cise questions…and then be asked others.

The anchors were fun. It was fas­ci­nat­ing to observe, behind the scenes, the mak­ing of a news pro­gram: con­stant last-minute appar­ent chaos, the lawyer in the “ask the lawyer” seg­ment nowhere to be found…but every­one seem to had a fun time. And good men­tal stimulation-as long as they man­age stress well.

Here you have the 3-minute clip from the local CBS’ Good Day Sacra­mento pro­gram, with a brief Q&A and a cou­ple of brain teasers (Count the Fs and Stroop Test).

The 3 ques­tions I was expect­ing were:

- What is Brain Aware­ness Week? see Dana’s and part­ners’ out­reach events world­wide.

- What is Sharp­Brains? see Our Vision for Brain and Mind Fitness.

- What is the involve­ment of Sharp­Brains dur­ing Brain Aware­ness Week? check Brain Aware­ness Week.

Next time I will give more clear direc­tions and maybe improve my Eng­lish a bit too if I can…

If you want more teasers, here you have Top 10 Brain Teasers.

Today is Inter­na­tional Women’s Day 2007.

Global con­sult­ing com­pany Accen­ture orga­nized a series of events, and I was for­tu­nate to lead a fun work­shop on The Neu­ro­science of Stress and Stress Man­age­ment in their San Fran­cisco office, help­ing over 125 accom­plished women (and a few men) learn what stress is, its impli­ca­tions for our brain func­tion­ing, per­for­mance and health, and of course some tips and tech­niques to develop our “stress man­age­ment” mus­cles. It was an honor to be able to wrap up a great event that included Dis­trict Attor­ney Kamala D. Har­ris, two of the co-authors of This is Not the Life I Ordered, a video by Sen­a­tor Dianne Fein­stein, and some great Accen­ture women.
