“Whatever you struggle with in a sense as it stems from your neurology, the inherent plasticity of the brain gives you a basis for improvement. This is a way underutilized and under-appreciated resource that well all have.” Dr. Michael Merzenich on the Brain Science Podcast #54, 2/13/09.

Recently there has been growing controversy about the effectiveness of computer-based cognitive training programs. As a co-founder of Posit Science, Inc. Dr. Michael Merzenich is a staunch defender of the methods his company uses to validate the programs that they have developed. But for the purposes of this essay, I want to share some of the key ideas we discussed during his recent interview on the Brain Science Podcast.

First of all, I asked him to discuss some of the highlights of his long career. Since he was one of the first neuroscientists to embrace the concepts of neuroplasticity I was curious about how this came about. While he did have some exposure to the animal evidence as a graduate student, it was actually his experience with the invention of the cochlear implant that convinced Dr. Merzenich of the real-world, practical implications of brain plasticity. The quality of the Read the rest of this entry »

I first discovered Norman Doidge’s book, The Brain That Changes Itself, in a May, 2007 review in the New York Times. Intrigued, but caught up in myriad end-of-school-year responsibilities, the book was put out of my mind until later that summer, when our school’s learning specialist emailed to say she had just finished a fascinating book. The Brain That Changes Itself: Stores of Personal Triumph from the Frontiers of Brain Science, is a compelling collection of tales about the amazing abilities of the brain to rewire, readjust and relearn after having a slice of itself rendered dysfunctional. The first seven chapters captivated me for their personal stories; the final four chapters for the science and philosophy.

Part of what makes Doidge’s writing so accessible is he tells stories, and his stories just happen to incorporate brain science. As a result, his book is easy to digest. The neuroscience behind Doidge’s book involves neuroplasticity, which is the brain’s ability to rewire itself. This means that the brain – our intelligence – is not something fixed in concrete but rather a changing, learning entity. On the face of it, this concept should not sound unusual, for it is what happens to individuals all the time as we go about the learning process, from infancy onwards.

What separates the stories in this book from daily learning is that Read the rest of this entry »
