what right hemisphere control
The brain's right hemisphere controls the muscles on the left side of the body, while the left hemisphere controls the muscles on the right side of the human body. When you wink your right eye, that's the left side of your brain at work. Because of this criss-cross wiring, damage to one side of the brain affects the opposite side of the body. In general, the left hemisphere is dominant in language: processing what you hear and handling most of the duties of speaking.
