Effects of externally applied electrical stimulus on brain relationship during isometric contraction of hand muscle

Communications exists between the peripheral muscles and the sensorimotor cortex, which controls the movement functions in the brain. There are five brain’s natural oscillations classified as delta, theta, alpha, beta and gamma which governed most general dynamics in the brain. It is proven that inc...
