The Performance Cortex:
How Neuroscience Is Redefining Athletic Genius by Zach Schonbrun. Penguin

Many
years ago, I recall reading an article about how Tiger Woods learned to golf so
well by the scientific methods taught to him by his father. Curious, I never pursued that interesting fact,
but it came to mind again with this book about the brain and athletic performance. The brain can be trained for athletic
performance up to a certain age, exemplified by the author’s reference to
Michael Jordan who had an interest in baseball but couldn’t grow in the
required skills and yet had what was needed for baseball.
Dagmar
Sternad has an Action Lab at Northeastern University. Here she experimented with the game skittles,
demonstrating how timing from the brain and physiology conspires to make us
winners or losers and how movement or kinetic patterns and features could be
retained for up to eight years. There is
also an interesting discussion of skills that are learned and involve brain
activity but can not develop further because of “habit” that negates any
further learning curve from progressing. This involves “action controllers,
“automatization” or even “muscle memory” as an action or sequence of actions
that get formed, reorganized and consolidated in our long-term memory. And so it goes.
These
are a few of the examples and explanations that tell the story of athletic and
normal action in an understandable presentation, such as the reflex arc, the
feed-forward loop of sensory-to-motor connections that trigger everyday actions
or the position of neural swing decisions in baseball, tennis and volleyball
serves.
The
factor of intention is also discussed as in using a scalpel to operate or to
murder. The same applies about these
motor skills applied to kinematics or movement.
All in all, “stimulus-response connections build up a nervous system of
sets which function like cognitive maps.”
The
authors even describe how “virtual arms” learn to operate or are taught by
science to understand the training behind using these prostheses.
Anyone
interested in physical activity, sports, coaching etc. will find this book
fascinating and interesting for practice or just understanding the theories and
applications that apply when playing or watching sports. Highly recommended and engaging science in a
credible, readable book. Nicely done,
Zach Schonbrun!
