By concentrating, I am able to produce a sensation throughout my body in my nervous system. Anywhere from my brain to my toes works. Given that any sensation is the passage of an electromagnetic signal, what is the physiological effect of this on my nervous system? Could it be that I am capable of "massaging" my nervous system? Or am I contrubuting to wear of my nervous tissue? Perhaps there is no effect at all?
