Left and Right Hemispheres (LH and RH)

Although the cerebrum is symmetrical in structure, with two lobes emerging from the brain stem and matching motor and sensory areas in each, certain intellectual functions are restricted to one hemisphere. A person’s dominant hemisphere is usually occupied with language and logical operations, while the other hemisphere controls emotion and artistic and spatial skills. In nearly all right-handed and many left-handed people, the left hemisphere is dominant.

In general, the right cerebral hemisphere controls the left side of the body and the left cerebral hemisphere controls the right side of the body.
