Brain Connection: Eric Jensen on Learning and the Brain

Eric Jensen is a former middle school teacher and former adjunct professor for several Eric Jensen Learning and the Brainuniversities including the University of California, San Diego. He co-founded the Learning Brain Expo, a conference for educators, and has written 21 books on the brain and learning. Jensen is currently completing his PhD coursework. His most recent book, Enriching the Brain: How to Maximize Every Learner’s Potential (Jossey-Bass, 2006), is highly recommended for educators and parents alike. He wrote this recent article in Phi Delta Kappan in February 2008, sparking a healthy debate on the value of neuroscience applied to education.Eric, thank you for your time. Can you explain the role that you and your organization play?

We act as translators between the neuroscience and education fields, helping to build a Brain-Based Education movement. We launched the first conference that attempted to bridge these two worlds in 1998. The goal of the conference, called Learning Expo, was for teachers to speak to scientists, and, equally important, for scientists to speak to educators.

Critics say that neuroscience research can add little to educational practices. What we say is that, whereas it is true that much needs to be clarified, there are already clear implications from brain research that educators should be aware of. For example, four important elements that are often neglected by educators, given the obsessive focus on academic scores, are nutrition, physical exercise, stress management, and overall mental enrichment.

On The Brain

neuronsVery intense week, and very fun. I will be writing more about this week’s 3 speaking events, but let me say now that our key messages

1) our brains remain flexible during our lifetimes,

2) we can refine our brains with targeted practice,

3) good brain exercise, or “mental cross-training”, requires novelty, variety, and increasing level of challenge (but without creating too much stress),

are being very well accepted from both healthy aging and workplace productivity points of view. We have ONE brain: health and productivity are 2 sides of the same coin.

If you want to make sure we learn more about our brains, you can help fellow blogger Shelley Batts get a college scholarship by voting here. She has a great neuroscience blog, is now finalist in a competition to win a nice scholarship, and needs out help.

Have some more time? You can watch this excellent 90-second video of cognitive neuroscientist Dr Lisa Saksida doing yoga in front of the fire while explaining the nature of Brain and Mind (via MindHacks). Quotes:

“I wish people understood that there is no mind/brain duality. Specifically, I wish people understood that there is no such thing as a purely psychological disorder. Every event in your psychological life, and therefore every psychological change, is reducible in theory to events and changes in your brain. We should therefore not judge people differently, according to whether they are considered to have a ‘psychological’ as opposed to a ‘neurological’ problem.”

“Of course, a lack of mind/brain split does not mean that we should abandon all talk of psychology. Psychology and neuroscience are two ways of studying the same thing, and both are essential for understanding the human condition.”

Neuroplasticity 101 and Brain Health Glossary

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“.

fmri.jpgThanks 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 Read the rest of this entry »

11 Neuroscientists Debunk a Common Myth about Brain Training

Last Monday, NPR (very good US-based radio station) had a program on “do brain training programs work?” that reflected very old-fashioned thinking. In short, the guest speakers talked and talked about the importance of nutrition and physical exercise (both very important, as we have covered in this blog multiple times), and expressed skepticism about the concept of exercising our brains to improve attention, memory and other skills…I guess it takes a while to change old mental paradigms (And yes, some programs work better than others).

Neuroscientists have finally debunked that old thinking that our brains decline inexorably after a certain age with little each of us can do to “exercise” or “train our brains”. But don’t trust me. During the last year I have had the fortune to interview 11 cutting-edge neuroscientists and cognitive psychologists on their research and thoughts. Here are some of my favorite quotes (you can read the full interview notes by clicking the links):

Judith Beck ”Today, thanks to fMRI and other neuroimaging techniques, we are starting to understand the impact our actions can have on specific parts of the brain.”- Dr. Judith S. Beck, Director of the Beck Institute for Cognitive Therapy and Research, and author of The Beck Diet Solution: Train Your Brain to Think Like a Thin Person. Full Interview Notes.

 

James Zull“Learning is physical. Learning means the modification, growth, and pruning of our neurons, connections–called synapses– and neuronal networks, through experience…When we do so, we are cultivating our own neuronal networks. We become our own gardeners”- Dr. James Zull, Professor of Biology and Biochemistry at Case Western University. Full Interview Notes.

 

Dr. Elkhonon Goldberg“Exercising our brains systematically is as important as exercising our bodies. In my experience, “Use it or lose it” should really be “Use it and get more of it”.- Dr. Elkhonon Goldberg, neuropsychologist, clinical professor of neurology at New York University School of Medicine, and disciple of the great neuropsychologist Alexander Luria. Full Interview Notes.

 

Picture of Daniel Gopher “What research has shown is that cognition, or what we call thinking and performance, is really a set of skills that we can train systematically. And that computer-based cognitive trainers or “cognitive simulations” are the most effective and efficient way to do so.” – Dr. Daniel Gopher, Director of the Research Center for Work Safety and Human Engineering at Technion Institute of Science. Full Interview Notes.

 

Yaakov Stern“Individuals who lead mentally stimulating lives, through education, occupation and leisure activities, have reduced risk of developing Alzheimer’s symptoms. Studies suggest that they have 35-40% less risk of manifesting the disease”- Dr. Yaakov Stern, Division Leader of the Cognitive Neuroscience Division of the Sergievsky Center at the College of Physicians and Surgeons of Columbia University, New York. Full Interview Notes.

 

Go Hirano“It is hardly deniable that brains enchant Japanese people. We love brain training. Dentsu, the biggest advertising agency, announced the No.1 Consumer-chosen 2006 Product was game software and books for brain training.“- Go Hirano, Japanese executive, founder of NeuWell. Full Interview Notes.

 

 

Picture of Brett Steenbarger “Elite performers are distinguished by the structuring of their learning process… It is important to understand the role of emotions: they are not “bad”. They are very useful signals. It is important to become aware of them to avoid being engulfed by them, and learn how to manage them.” – Dr. Brett Steenbarger, Associate Professor of Psychiatry and Behavioral Sciences, SUNY Medical University, and author of Enhancing Trader Performance. Full Interview Notes.

 

torkel_s.jpg“We have shown that working memory can be improved by training…I think that we are seeing the beginning of a new era of computerized training for a wide range of applications” – Dr. Torkel Klingberg, Director of the Developmental Cognitive Neuroscience Lab at Karolinska Institute. Full Interview Notes.

 

 

Bradley S. Gibson, Ph.D.Training is very important: attentional control is one of the last cognitive abilities to develop in normal brain development…I can easily see the relevance in 2 fields. One, professional sports. Two, military training.”  Professor Bradley Gibson is the Director of the Perception and Attention Lab at University of Notre Dame. Full Interview Notes.

 

 

Arthur LavinI don’t see that schools are applying the best knowledge of how minds work. Schools should be the best place for applied neuroscience, taking the latest advances in cognitive research and applying it to the job of educating minds.” – Dr. Arthur Lavin, Associate Clinical Professor of Pediatrics at Case Western School of Medicine, pediatrician in private practice. Full Interview Notes.

 

David Rabiner“Cognitive training rests on solid premises, and some programs already have very promising research results. Some of the most are promising areas are: neurofeedback, which as a whole is starting to present good research results, and working memory training.” – Professor David Rabiner, Senior Research Scientist and the Director of Psychology and Neuroscience Undergraduate Studies at Duke University: Full Interview Notes.

 

There is much we can do everyday to literally exercise our brains. No matter our age. So much to Learn…so Good to Learn! Let’s see when this story makes it into NPR.
