The Choreographing Brain
Brain dominance begins early – 22 days after conception the spinal cord and brain appear. Week 4 the eyes, nose, ear and mouth form. Week 28 thalamic brain connections form to mediate sensory input. The brain is a three pound winked mutable (changeable) mound influenced by lived moving experience, bodily feelings, perceptions, culture, society, and the environment.
The brain is comprised of about 100 billion electrically active neurons (cells), each connected to tens of thousands of its neighbors at perhaps 100 trillion synapses (the spaces between neurons where information transfers can occur). These atoms of thought relay information through voltage spikes that convert into chemical signals to bridge the gap to other neurons.
Many parts of the brain make a dance
More than 400 studies related to interdisciplinary neuroscience reveal the hidden value of dance. For instance, we acquire knowledge and develop cognitively because dance bulks up the brain. Consequently, the brain that “dances” is changed by it. As neuroscientist Antonio Damasio points out, “learning and creating memory are simply the process of chiseling, modeling, shaping, doing, and redoing our individual brain wiring diagrams.”
Dance is a language of physical exercise that sparks new brain cells (neurogenesis) and their connections. We thought that humans had limited brain cells that decreased with age. But now, beginning my eighth decade, I’m still dancing—now flamenco, belly dance, jazz, and salsa!
The neuron connections are responsible for acquiring knowledge and thinking. Dancing stimulates the release of the brain-derived protein neurotropic factor that promotes the growth, maintenance, and plasticity of neurons necessary for learning and memory. Plus, dancing makes some neurons nimble so that they readily wire into the neural network. Neural plasticity is the brain’s remarkable ability to change throughout life.
