What do the hemispheres in the brain control?

The left hemisphere of the human brain controls language, and thinking skills, and the right hemisphere controls all motor functions.

Any thought that person has is derived from the left hemisphere of that person's brain. If a person is speaking, the words are being formed in the left hemiphere, but in order for the mouth to open and for the tongue and lips to move in order to be able to speak the words, the right hemisphere needs to work.

If a person picks up a ball and then throws it, that person's brain's right hemisphere was working. A person reaches out and touches a pan. The pan is on the stove and is very hot, and when the person touches it, that person's hand jerks away from it. The arm reaching out to touch the pan was a voluntary action, but the hand jerking away was a reflex, which is an involuntary action.

Involuntary actions or movements are not controlled by the brain at all. A reflex is when the nerves detect something harmful (i.e. skin contact to a hot object, or cutting one's self against something sharp accidentally) and the nerves in the spine detect the nerve impulses and automatically send a new impules to the motor nerves of the muscle that can move the body away from harm (i.e. the hand touching something hot and then being jerked away).

If you're smelling burning hair or it smells like something is burning all the time, I would suggest getting into an ENT physician ASAP as this is absolutely irreversible.
