The Developing Brain Part Four

Marian C. Diamond, PhD. - The Constantly Adapting Brain

Marian C. Diamond, Ph.D, a neuroscientist at U.C Berkeley did research on the neuroanatomy of the forebrain, notably the impact of the environment on brain development, published under the title Enriching Heredity: The Impact of the Environment on the Anatomy of the Brain. Marian describes how rich interaction with the environment literally grows and shapes the brain lifelong. “There are a hundred billion nerve cells in a brain and many of those nerve cell can make connections with thousands of others. A single nerve cell can receive as much input from about 20,000 other cells, so you think of the computation that goes on in a single cell before it fires. The interaction of the environment with this system is extremely dynamic and important. One can say that the brain is responding to the external environment and to the internal environment at all times. The nerve cells are designed to receive stimuli, store information and transmit information.  Every cell receives input from both the internal and the external environment at all times.  And we've shown that we can (physically) change the brain by changing the internal and external environments at any age.”

Marinated Minds

My wife and I went to a meeting for several hours. When we returned we both remarked that Carly Elizabeth had changed and indeed she had. No surprise here. She is changing every moment. We simply aren’t acute enough to notice. This morning she climbed the wood stairs hefting one of my shoes then scooted down, face first, carefully and skillfully on her way to the leather sofa that she now uses like a baby trampoline, exploring the bounce and uneven surfaces, smiling and uttering a variety of sounds as if to say, “there!” It was only a few weeks ago that she began to walk. Today it is a near constant joyful run. That is how fast her constant changing is.
