Throughout our lives, we develop patterns of dominance, strength, weakness, tightness, etc. We always eat with our right hands, or write, or cut, or whatever daily activities we engage in. The result of this is one side that is not only more skilled and the other side is lacking those skills and messages from the brain. In addition, most musicians' instruments put more strain on one side rather than the other, depending on the instrument and the setup, and constant use of the same side in dominance, music, writing, typing, texting, and mouse-use can be taxing on your soft tissues. I have the good fortune of being left hand dominant and slightly ambidextrous-I don't always notice what side I'm doing something on until someone points it out to me ("You eat with your right?" "You kick with your right?" "You put mascara on with both hands depending on the eye?"). In addition, most of the world caters to the right-handed folks, so I've learned to do everything with my right side, except write quickly and neatly.
-There has been some research that musicians who use both hands for their instrument have more connection between the right and left hemispheres of the brain than "normal" people (whoever those folks are).
- Every time you do a new movement pattern, whether in music, exercise, life, etc., you have the opportunity to create a new neural pathway. (Read about neural pathways!)
-Neuroplasticity refers to the idea that the brain changes itself, whether from trauma or training, and creates new neural pathways throughout life, but also loses certain pathways.
And here's an interesting passage from Dr. Gene Van Tassel:
"Neurons which are not stimulated in these pathways tend to wither away and become unusable. These neuron cells either die or change in ways which render them ineffective. If pathways are never developed, they never become usable in the sense that they can handle significant traffic in terms of electrochemical communication within the brain. If neuron cells are not used, they can be lost. "
I am by no means a brain whisperer, but I do love a good movement challenge, especially if it challenges the fine motor skills. So here's your activity challenge: Use your non-dominant side for daily activities!
Sleep on your opposite side (if you're a side sleeper)
Brush teeth with other hand
Eat with other hand (and open fridge with other hand)
Hold cup with less used hand
Use doorknobs with less used hand
