Welcome to the first edition of MetaCarnival: a Carnival of Carnivals (announced here), the new, monthly, and interdisciplinary gathering of blogs and blog carnivals.

Let's picture all participants in the shadow of an expansive sycamore tree, conducting a lively Q&A lunch discussion.

General Advice

Q: What would you recommend to live as long as possible, and as healthy as possible?
- Hourglass (biology of aging): Try Not To Stab Yourself Repeatedly. Or smoke. Or eat that much fast food...you get the idea.  "The vast majority of people are quite comfortable engaging in habits that cause great harm to the old person they will one day be, cutting off years or even decades of health."

Q: Can blogging help, too?
- I and the Bird (birds): Indeed. Just read about these life-changing moments in the Kenyan highlands, brought together spontaneously as a collaboration between researchers, conservationists, bloggers. And, yes, birds.

Sports (Well... Brain and Sports)

Q: Tell me something interesting about athletes and "The Zone".
- Encephalon (neuroscience and psychology): why don't we review this recent study on the Momentum Chain in Sports. You can conduct your own mini experiment while watching TV: watch the reactions of the players and the teams right after "precipitating events" to see if they actually lead to game-changing moments.

Medicine

Q: Should patients be patient?.
- SurgeXperiences (surgical experiences): Patience in indeed a virtue, especially Continue Reading »

An excellent new edition of Encephalon neuroscience blog carnival, hosted by Mind Hacks. Enjoy!

If you are a blogger or read blogs often, you know that there are a good number of excellent blog carnivals focused on specific themes. If you are interested in medicine, you know what carnival to visit. Education, the same. Biology, neuroscience, nursing, birds, aging, philosophy...a variety of topics are very well covered in the blogosphere.

What you probably haven't come across is a high-quality "metacarnival" or "carnival of carnivals", where you can read the best blog posts ACROSS topics, subjects, disciplines.

This is why a few blog carnival "organizers" are launching next Monday a monthly rotating "MetaCarnival" to feature the most interesting posts from a variety of high-quality blog carnivals.

Participating blog carnivals so far, alphabetically: Continue Reading »

We read today how Panel Urges Schools to Emphasize Core Math Skills (Washington Post). Now, there is a more fundamental question to consider: what should the schools of the XXI century look like and do?.

To create a much needed dialogue, I asked one the most thoughtful education bloggers around to share her (I guess it's "her") impressions with us. Enjoy!

What do we want our schools to do, and for whom? 

--By eduwonkette

"Schools," Stanford historian David Labaree wrote, "occupy an awkward position at the intersection between what we hope society will become and what we think it really is." What do we want our schools to do, and for whom?

Schools, like most organizations, have many goals. These goals often compete with and displace each other. Relying heavily on the work of David Labaree, I will discuss three central goals of American schools – social efficiency, democratic equality, and social mobility. Throughout the history of American education, these goals have been running against each other in a metaphorical horserace. While they are not mutually exclusive, the three goals introduce very different metrics of educational success. More often than not, they sit uncomfortably with each other.

Great news: I have been invited to be one of the bloggers at that fun news and blogging experiment called The Huffington Post. I appreciate very much the opportunity to engage a broader community around the latest research on brain fitness and the brain fitness market, and around how to "exercise our brains" for happiness, health, lifelong learning and peak performance.

You can take a look at the first post: How "Saying Thanks" Will Make You Happier.

SharpBrains.com/blog will keep being our main blog. Thank you for all your support!

Psychologist Robert Emmons recently told us about the many benefits of practicing gratitude.

- "First, the practice of gratitude can increase happiness levels by around 25%. Second, this is not hard to achieve - a few hours spent writing a gratitude journal over 3 weeks can create an effect that lasts 6 months if not more. Third, that cultivating gratitude brings other health effects, such as longer and better quality sleep time."

Thanksgiving flew by for me this year without my taking the time to express gratitude to many of the people who have been so generous with their time and advice.

Given that this is a blog, I would like to say Thank You! to the following bloggers Continue Reading »

An anonymous reader of Andrew Sullivan's blog writes a superb comment, reproduced here:

"One thing Watson and others forget is that the brain is highly malleable based on environment. Although he is the father of DNA he knows very little about neuroplasticity and neurogenesis. Previously it was thought that the human brain was 'hardwired' after a certain age. This is not true. Not only is not true, but the human mind is capable of adaptation but actual neuron growth even late in life. Ten years ago this was thought impossible.

Neurogenesis and neuroplasticity proves that a nurturing social and family setting shifts IQ, perspective, and emotional IQ. The so-called bell curve isn't genetic. Oppressed Tibetans and Chinese ethnic minorities -whose test scores soar in the United States and Canada- are 20-30 points lower in their homeland. That 20-30 points deficit is in the same range of a lot of groups that are attacked or threatened (Muslims in France, Christians in Nigeria, Blacks in America). Conversely when oppressed groups are removed from their environment their IQ, emotional health returns to a normal rate, thus proving that is NOT genetic.

It is plastic, shifting and based upon the environment.

That is why people Continue Reading »

Given the growing number of articles in the popular press mentioning words such as "neuroplasticity", "fMRI" and "cognitive reserve", let's review some key findings, concepts and terms.

First, a prescient quote by Spanish neuroscientist Santiago Ramon y Cajal (1852-1934): "Every man can, if he so desires, become the sculptor his own brain".

Thanks to new neuroimaging techniques, regarded “as important for neuroscience as telescopes were for astronomy”, neuroscientists and cognitive psychologists have been finding that the brain has a number of "core capacities" and "mental muscles" that can be exercised through novelty, variety and practice, and that exercising our brain can influence the generation of new neurons and their connections. Brain exercise is being recognized, therefore, as a critical pillar of brain health, together with nutrition, physical exercise and stress management.

Previous beliefs about our brain and how it works have been proven false. Some beliefs that have been debunked include claims that adult brains can not create new neurons (shown to be false by Berkeley scientists Marian Diamond and Mark Rosenzweig, and Salk Institute’s Fred Gage), notions that working memory has a maximum limit of 6 or 7 items (debunked by Karolinska Institute’s Torkel Klingberg), and assumptions that the brain’s basic processes can not be reorganized by repeated practice (UCSF’s Drs. Paula Tallal and Michael Merzenich). The "mental muscles" we can train include attention, stress and emotional management, memory, visual/ spatial, auditory processes and language, motor coordination and executive functions like planning and problem-solving.

Mental stimulation is important if done in the right supportive and engaging environment. Stanford’s Robert Sapolsky has proven that chronic stress and cortical inhibition, which may be aggravated due to imposed mental stimulation, may prove counterproductive. Having the right motivation is essential.

A surprising and promising area of scientific inquiry is Mindfulness-Based Stress Reduction (MBSR). An increasing number of neuroscientists (such as University of Wisconsin-Madison’s Richard Davidson) are investigating the ability of trained meditators to develop and sustain attention and visualizations and to work positively with powerful emotional states and stress through the directed mental processes of meditation practices.

And now, some keywords:

Brain Fitness Program: structured set of brain exercises, usually computer-based, designed to train specific brain areas and processes in targeted ways.

Chronic Stress: ongoing, long-term stress, which blocks the formation of new neurons and Continue Reading »

Professor, trader and author Brett Steenbarger, one of the main experts on Trading psychology and Trader Performance (see our interview with him here), just announced he will speak at a Free Interactive Webinar on Trader Performance

• "During the Webinar, I will summarize and elaborate basic ideas from my book and also introduce new ideas developed and applied since the book's publication. A unique feature of the session will be a participant Q&A moderated by Steve." (Steven Buss, a member of the NeoTicker forum)

He recently wrote a great post on My Favorite Techniques for Overcoming Performance Anxiety in Trading, including a wonderful technique (see article to read the full description)

• "Of late, I've been making use of heart rate variability feedback through the Freeze-Framer program, which offers a nice graphical interface to help users track their progress and visually determine whether or not they're in "the zone".
• "Once the trader becomes adept at this, I then add Continue Reading »

Cognitive training and stress management, MindFit and Freeze-Framer (or emWave): two complementary sides of Brain Fitness.

Research shows that adults can and should take care of their brains, both for short-term and long-term benefits. Through brain exercise we can improve our overall cognitive function right now—making quick decisions, staying calm and focused under pressure, and multitasking effectively. Over time, we may not reduce our brain age, but we can build up a cognitive reserve to buffer against age-related cognitive decline or other progressive diseases. Short term and long term, we all want to lead productive, successful lives.

Any good brain fitness program must provide you a variety of new challenges over time. While recreational activities like bridge, sudoku, and crossword puzzles can work our brain, only a comprehensive tool based in scientific research, like MindFit, can work your mental muscles systematically through a completely individualized training regimen for Continue Reading »
