The neuroscience of language, consciousness, and communication raises many fundamental questions, the answers to which consistently defy definition. For example: when we speak, where do our words come from? Our brain, or our mind? And what do we mean by mind? Similar dilemmas arise when we try to study the nature of consciousness. What is it, and where is it? Is it generated solely by neural activity, or is it a separate force that influences the activity of the brain? Hypotheses abound, but nobody seems to know for certain.
However, we do have a few clues that illuminate the relationship between the brain, the mind, and Read the rest of this entry »

The Sound of Music
Whether you realize it or not, you already know a lot when it comes to music. According to Daniel Levitin, former record producer, current neuroscientist, psychologist and author of This Is Your Brain On Music, you know: Read the rest of this entry »

The frontal lobes of the brain (in gray here) have been compared to an orchestra conductor, influencing, directing, and moderating many other brain functions. Indeed, the frontal lobes support the so-called executive functions: decision-making, problem-solving, planning, inhibiting, as well as other high-level functions (social behavior, emotional control, working memory, etc.).

My interest in the brain stems from wanting to better understand both how to make school more palatable for students, and professional development more meaningful for faculty. To that end, I began my Neurons Firing blog in April, 2007, have been doing a lot of reading, and been attending workshops and conferences, including Learning & the Brain.
If you agree that our brains are designed for learning, then as educators it is incumbent upon us to be looking for ways to maximize the learning process for each of our students, as well as for ourselves. Some of what follows is simply common sense, but I’ve learned that all of it has a scientific basis in our brains. Read the rest of this entry »

(Editor’s Note: What follows is an excerpt from Dr. Robert Sylwester’s new book, A Child’s Brain. The Need for Nurture (2010) Corwin. In this excerpt, Robert Sylwester synthesizes the first 20 years of development and shows how it can be viewed as a “rhythmic four-six-four-six-year developmental sequence”)
Chapter 4: Development and Growth.
The First 20 years.
To simplify a complex phenomenon, we can divide our 20-year developmental trajectory into two periods of approximately 10 years each. The developmental period from birth to about age 10 focuses on learning how to be a human being – learning to move, to communicate, and to master basic social skills. The developmental period from about 11 to 20 focuses on learning how to be a productive reproductive human being – planning for a vocation, exploring emotional commitment and sexuality, and achieving autonomy.
The first four years of each of these two decade-long development periods are characterized by slow awkward beginnings to a six-year normal move toward confidence and competence. For example, crawling leads to toddling leads to walking leads to running and leaping.
We’ve designed our preschool, elementary school, middles school, high school and initial college systems around this rhythmic four-six-four-six-year developmental sequence. We tend to keep small children at home during their first four years to allow them to begin their development in a sheltered family environment without state standards and assessment programs. They learn basic motor skills, how to talk, and how to get along with their families. In essence, they develop a basic understanding of how their sheltered world works.
At about five years, we say, in effect, Read the rest of this entry »

The July/ August 2009 issue of The Journal on Active Aging includes my article Why We Need to Retool “Use It Or Lose It“
“By now you have probably heard about brain plasticity, the lifelong capacity of the brain to change and rewire itself in response to the stimulation of learning and experience. The latest scientific research shows that specific lifestyles and actions can improve the health and level of functioning of our brains, no matter our age.
Of particular importance to maintaining cognitive functioning through life are the hippocampus (deep inside the brain, part of what is called the limbic system), which plays a role in learning and memory; and the frontal lobes (behind your forehead), which are key to maintaining decision-making and autonomy. Is there a way to physically protect these parts of the aging brain? Yes. But the right answer is far from “do one more crossword puzzle” or “do more X” (whatever X is). The key is to add significantly different activities to ensure a flow of novelty, variety and challenge, combining physical and mental exercise while not ignoring factors such as stress management and balanced nutrition.
We need, in other words, to retool our understanding and practice of “Use it or lose it.” We must focus on the importance of getting out of our physical and mental routines and activities to get the benefits of real exercise—physical and mental.”

Here you have the presentation I delivered on Tuesday at ETech 2009 (this year’s O’Reilly Emerging Technology Conference):
Emerging Research and Technology for Life Hacking/ Brain Training
(click to open presentation in new window)
Description: Life hacking. Brain training. They are one and the same. The brain’s frontal lobes enable our goal-oriented behavior, supporting executive functions, such as decision-making, attention, emotional self-regulation, goal-setting, and working memory. These functions can be enhanced with targeted practice such as life hacking. This session will provide an overview of the cognitive neuroscience underpinning life hacking, and review the state-of-the-art of non-invasive tools for brain training: neurofeedback, biofeedback, software applications, cognitive simulations, Transcranial Magnetic Stimulation, and plain-old meditation.
It was great to meet fellow bloggers and presenters, such as Shelley Batts of Of Two Minds and Chris Patil of Ouroboros, and very inquisite and throughful audience members. Getting ready to speak at ASA/ NCOA and IHRSA next week!
