Consider for a moment an athlete’s body, let’s say, a gymnast’s form. Not only does she have a highly trained musculature, but maybe more importantly, through her years of training, she has developed a greater ability to coordinate her physical movements. In the same way that her muscles have become stronger through physical training, her nervous system—via brain plasticity and the ability of the brain to grow and adapt based on stimuli—has likewise become more able to efficiently respond to the demands she is placing upon her mind and body.
For years, researchers have been investigating how the brain interfaces with the body in an effort to decipher the electrical language of mind. Research like that of Dr. Miguel Nicolelis at Duke University Medical Center has demonstrated that this language can be understood and harnessed to do things like power robotic prosthetics.
However controversial you might consider his work, Dr. Nicolelis’s discoveries are nothing short of—pardon the phrase—mind-bending, and are directly relevant to our talk about brain plasticity. In brief, Dr. Nicolelis’s recent research has focused on working with a rhesus monkey named Aurora. In short, through implants in her skull, Nicolelis was able to record Aurora’s motor nerve signals as she used a joystick to play a simple video game. He then used a computer algorithm to convert those signals into code to power a robotic arm. This led to two results.
First, as Aurora observed her own motions mimicked in the movements of the robotic arm, she began to be able to control the movements of the robot with her thoughts, and was able to use it to successfully manipulate the robotic arm to play the video game. What’s more, she figured out that she could control the robotic arm with her thoughts alone and without having to move her own arm and began to do so spontaneously. (See this article from Scientific American for detail, or read an excerpt about Aurora from Nicolelis’s book, Beyond Boundaries: The New Neuroscience of Connecting Brains with Machines and How it Will Change Our Lives.)
Likewise, this same ability has been documented in humans. Researchers at the University of Washington mapped signals from the surface of human subjects’ brains and harnessed them to control the movement of a computer cursor on a screen. With only ten minutes of training, subjects were able to figure out how to move the cursor using their minds alone. Maybe more importantly, “brain signals from imagined movement became significantly stronger than when actually performing the physical motion.”[i] According to Rajesh Rao, a UW associate professor of computer science and engineering, “the rapid augmentation of activity during this type of learning bears testimony to the remarkable plasticity of the brain as it learns to control a non-biological device.”[ii]
Because of brain plasticity and the ability of the mind to quickly adapt to such situations and deliver stronger signals through such training, robotic prosthetics that directly respond to thought are almost in humanity’s grasp; we’re beyond the phase of discovery and are now into the fine tuning to make the innovation truly useful. While such developments may not allow a paraplegic to jump out of a wheelchair and turn summersaults next week like our gymnast, the simple ability that so many of us take for granted, such as walking across a room, might be available within our lifetime.

Over the years, many people have speculated about the advantages and disadvantages of exposing an infant to a second language. On one hand, it sounds great to think that children could be proficient in two languages by the time they go to school but, on the other hand, there is the concern that adding a second language could cause confusion and even delay language development in very young children.
Fortunately, Janet Werker, a psychologist at Vancouver's University of British Columbia, and her colleagues discovered that learning two languages simultaneously does not cause confusion and, in fact, can give young children cognitive advantages over their monolingual peers. It now appears that bilingual children develop enhanced visual sensitivity to language as well as the auditory sensitivity that we would expect.
Most people in other countries speak multiple languages and researchers have not found real evidence of language confusion in children who learn more than one language at a time. Of course, infants and toddlers who grow up in bilingual homes often will mix the two languages and that ‘mixing’ even has a name: code-switching. By the time these babies are three years of age, they will move back and forth between the languages but they also naturally learn to follow rules that govern that movement. For example, if one parent is not bilingual, they stick to the dominant language for that parent but will code-switch with the bilingual parent.
The study[i] also tested visual-language discrimination with four, six and eight month-olds and found that at the two earlier ages, infants can distinguish between two spoken languages when looking at a video of a person speaking with the sound muted, even if they are only familiar with one of the languages. By eight months of age, the babies’ brains can even discriminate between two unfamiliar languages simply by watching someone speak. Further studies will determine how long this ability is maintained in childhood but it does appear that there is a lasting influence from early exposure to additional languages.
Research also indicates that babies growing up in a bilingual environment are better able to attend to perceptual cues such as a change in voice tone or facial expression, in both languages and can apply this ability to distinguish things in the world as well. Additional research [ii] suggests that bilingual children also could have more flexibility in learning.
So, if you speak two languages fluently, share them with your babies from day one. Expanding infancy with a second language could provide stronger cognitive skills, more perceptive social skills and better learning in general. Don’t worry about videos, flash cards or other fancy options for teaching babies a second language - just talk and read together!

Register today for one of six exclusive upcoming sessions:
Within the past seven years, researchers have discovered why some children struggle to learn math and reading skills. In general, studies show that the brain architecture—the pre-wired pathways for processing information—that children need to succeed in school is weak or underdeveloped in struggling learners. Studies have also proven that this architecture can be quickly and efficiently developed and fortified through brain fitness exercises that supplement curriculum.
Presenters for these exclusive Scientific Learning webinars will be Dr. Martha S. Burns, Director of the Clinical Specialist Market, and Sherrelle Walker, Chief Education Officer. Each session will include district results presented by long-time Scientific Learning customers, as well as a designated period for presenters to respond to your questions and answers.

This past September in a blog posting about the importance of physical exercise, I opened with a comment about the powerful pull that the video screen exerts on young brains. To be sure, this useful evolutionary adaptation has served us very well. Our instinctive ability to focus and concentrate on fast-moving, bright stimuli is a survival mechanism that allowed our ancestors to escape from many a tight spot. Even so, with the advent of modern technologies such as computers and television, we are now experiencing the down side of an endless flood of engaging electronic input. Research has shown that extensive screen time has the power to negatively affect our very chemistry and biology.
As we know from brain plasticity research, the stimuli we receive over time directly affect the development and wiring of the brain. Still, these effects are only the beginning of a long list of problems that screen time engenders. This past September, British psychologist and biologist Aric Sigman published an article in the British MailOnline that pulls together the conclusions of recent research from around the globe, painting a clear picture of the deleterious effects of screen time, and that picture is far from pretty. In fact, it is one that we, as parents, as teachers and as members of a national community, must not ignore.
While screen time has been shown to have negative psychological effects, I found Sigman's run-down of the chemical and biological effects to be of particular concern:
Taken in sum, these studies are sending us a clear message that we as parents and educators must take to heart: the more these screen-based technologies occupy time in our days, the more vigilant we must be about maintaining our own healthy habits, as well as educating our students to the risks so they can make their own smart decisions and lead long, healthy lives.
Learn more about the effects of screen time:

Educators, researchers and education policy-makers have long discussed the benefits of structured music education. In today's environment of shrinking district resources, the arts are often early arrivals to the budgetary chopping block. Certainly, math, science, language arts and social studies are essential subjects, but we must also understand exactly what is lost when we cut arts programs. When we let go music education, we let rest layers upon layers of essential learning.
While all of these losses are arguably of equal importance, I wish to focus on the last. In their August 2010 article Music Training for the Development of Auditory Skills, Nina Kraus and Bharath Chandrasekaran present the neuroscience research demonstrating that music training, in the same way that physical exercise impacts body fitness, "tones the brain for auditory fitness." Specifically, Kraus and Chandrasekaran examine three specific areas of brain function where music training positively affects function:
Based on this information, Kraus and Chandresekaran argue "that active engagement with music promotes an adaptive auditory system that is crucial for the development of listening skills. An adaptive auditory system that continuously regulates its activity based on contextual demands is crucial for processing information during everyday listening tasks."
Kraus and Chandresekaran end their article with a discussion of the implications for education. All of the skills and abilities discussed above clearly have the potential to impact student success and achievement "by improving learning skills and listening ability, especially in challenging listening environments." Whether considered as content, as skills or as brain processing exercise, the benefits of music should be carefully weighed as we evaluate its place in the school day.

Last week I was sitting in a fast-food drive-thru when I noticed the car in front of me held what appeared to be an under-age driver and friend. They placed their order and pulled forward barely able to see over the steering wheel and dashboard. I am thinking, oh dear, do the parents know they have taken the car? As their order was handed out of the drive-thru window both seats popped up simultaneously revealing two teenage boys. I guess it’s cool to go through the fast-food drive-thru with the car seats fully reclined!
How do you explain adolescent behavior? This, of course, is the million dollar question that has been asked by adults for a long time. A question that finally has some answers coming out of brain research. So, you may ask, what does the brain have to do with adolescent behavior? Well, actually everything!
One very important factor to note is the adolescent brain is still under construction; something we tend to forget when we look at these “young adults.” Instead of thinking of the adolescent brain as a house that is completely built and only needs to have furnishings added, we need to think of the adolescent brain as a house that is only framed and still needs walls, wiring and a roof. (1, p167)
Sheryl G. Feinstein, author of Secrets of the Teenage Brain: Research-Based Strategies for Reaching and Teaching Today’s Adolescents, Second Edition, discusses the many aspects of the adolescent brain giving rise to an understanding it is a whirlwind of complexities and contradictions. She notes in the chapter on cognition and learning the adolescent brain is particularly susceptible to novelty, overcomplicates problems, idealizes the world, and has one saying one thing while doing another. In looking at the social brain and communication, Feinstein points out, because the adolescent brain relies more on the amygdala (an area of the brain that processes and remembers emotions) than on the frontal lobes (the part of the brain that is involved in decision making, language, problem solving, planning and controlling sense of self) adolescents experience emotions before they can verbally articulate them, thus setting the stage for emotional outbursts. In addition, adolescent emotions can easily cement lifelong memories or form powerful learning blocks.
Anyone who has worked with adolescents knows how up and down they can be from day to day – some days they appear to be with it and other days you wonder if they are even on this planet. What we now know is adolescence is a time of great fluctuation in the levels of neurotransmitters, the chemical messengers in the brain that excite and inhibit behaviors. When levels of these chemicals go awry adolescents face a variety of mental upheavals that can lead to depression, eating disorders, and shifts in sleep habits.
And, let us not forget the risk-taking behavior adolescents’ exhibit that has adults shaking their heads in despair and wondering if they have a brain at all. Actually, it is the brain that is heavily involved in this risky behavior. Adolescents are very susceptible to the dopamine rushes (a chemical in the brain associated with pleasure) that comes with risk taking. Again, because they rely on the emotional amygdala more than the rational frontal lobes, adolescents have trouble foreseeing the consequences of risky behavior, and giving them the sense of invincibility. Maybe this sense of invincibility is one of the reasons they so closely relate to our fictional “super heroes.”
So, the next time an adolescent turns to you and says “WHAT are you looking at?” you know that is not an alien being from another planet, but rather someone who is “going through startling growth and streamlining in the brain; an intelligent creature not yet accustomed to their (unevenly) burgeoning mental strengths and capabilities.” (1, p167)
For anyone who works with, lives with, or even knows an adolescent, I encourage you to read the latest research and literature on the adolescent brain. There is a wealth of new information and insight into that enigma called “teenager.” Here are some good reads to get you started:

For this blog post, I offer two challenges, one for me and one for you:
Ready? Have you taken a breath and found your focus? On we go.
The brain is constantly changing and rewiring itself based on the stimulus it receives; in neuroscience, we call this "brain plasticity." As you read each word of this blog, the neural networks of your brain are active in response to the words, as well as the white noise of the air conditioning, the voices next door, the tempting smell of that banana, and the countless other stimuli in the room around you. Especially in the Internet-connected workplace, we are barraged with such stimuli, and we react in an effort to take advantage of every moment and every opportunity. (Have you gotten a "you've got mail" message since you started reading? That’s an opportunity! Don't give in. Stay focused. Keep reading.) While today’s world rewards speedy and often unfocused multitasking, we must still set time aside to "unplug" and reap the benefits of slowing down and engaging in deep, extended reading, writing and thinking.
How is today’s world of fragmented information affecting our brains? Think back (if you are old enough) to the days before the online information explosion. Consider the simple act of focused, quiet reading. In his book, The Shallows: What the Internet is Doing to Our Brains, Nicholas Carr describes "deep reading" as a "sustained, unbroken attention to a single, static object" that allows the reader to make "their own associations, draw their own inferences and analogies."
In contrast, think of how you read at your computer. In the June 6, 2010 New York Times article, "Your Brain on Computers: Hook on Gadgets, and Paying a Mental Price," Matt Ritchel reports on research that has shown how the constant incoming flow of information changes how we think and behave. Where is your focus as you read on your computer, clicking back and forth between your e-mail, your Facebook page, your Twitter feeds, the three blogs you follow and back to your e-mail? Ritchel cites research showing that computer users at work change windows or check e-mail or other programs nearly 37 times an hour. That means that in the computerized workplace, tasks receive on average less than two continuous minutes of focus.
(Have you been reading this for over two minutes without giving in to check your e-mail? If so, congratulations, you're above average for staying on-task. Keep it up.)
According to Carr’s report of the research, "when we go online, we enter an environment that promotes cursory reading, hurried and distracted thinking, and superficial learning."
Why do we allow ourselves to be drawn into such a state? Our human brains are programmed to respond to immediate opportunities and threats with a squirt of dopamine, a neurotransmitter associated with motivation and reward. Each new piece of information, every e-mail and tweet, is an opportunity that our brains evaluate. In essence, we are awash with stimuli that are constantly influencing brain plasticity. Added to that, research has shown dopamine to be addictive. Put those together, and the conclusion is undeniable: we are actively conditioning our brains away from the ability to maintain an extended focus on individual tasks.
Is it the fate of a technology-enabled humanity to be fragmented and frazzled? No, but I suggest that we need to intentionally set aside time for the deep reading, writing and thinking Carr describes. This is even more necessary if we are "plugged in" most of the day. We can and should for our own good turn off the computer and devote thirty minutes a day to focused, uninterrupted activities like reading a book, writing in a journal, playing a musical instrument or sketching a picture. While the technologies available to us to "plug in" for work and entertainment continue to bombard our days, we must bear in mind that such stimuli do have an effect on the ongoing development of our neural wiring, and that there are great benefits to be reaped from experiencing the world unplugged.
Now, were you able to read from beginning to end with no distractions? If not, don’t worry. This was a challenge designed to demonstrate how distractible the mind can be. On the other hand, if you were able to focus and read this entire message start to finish without giving into the pull of your e-mail or your Facebook friends, congratulations! Well done.
As promised, here are some links to continue your own reading on brain plasticity:
And how distracted are you? How well can you multitask?
