In nature everything that moves has a brain. Creatures that move about have to decide where to go, how to avoid obstacles and other functions that plants don’t have to deal with. Even the lowly little sea squirt, while it is young and swimming about, has a brain, however when it reaches maturity it attaches itself to a piece of coral. Now sedentary it proceeds to eat it’s own brain and becomes the ocean’s variety of couch potatoe. If being sedentary causes a loss of brains would physical activity improve the brain? Scientists are finding that it most definitely does. watch the video of Dr. Wendy A. Suzuki a Professor of Neural Science and Psychology in the Center for Neural Science at New York University. A prominent researcher in brain plasticity and long-term memory her research has focused on understanding how exercise can be used to improve learning, memory and higher cognitive abilities in humans.
