Roger Sperry did work on this in the early to mid '70s. The Mayo Clinic has done work on brain mapping to determine which parts of the brain control specific functions (prior to brain surgery, if I remember correctly), particularly for the treatment of traumatic brain injuries. The University of Utah has also done extensive studies on this topic. They concluded that it is a myth that we have a dominant side to our brains, but acknowledged that the different hemispheres controlled different functions.
According to Western Michigan University the left hemisphere of the brain controls right motor and sensory activities; is the location of reacting, language, and handwriting; and has the centers for speech and hearing. The right side of the brain, meanwhile, controls left motor and sensory activities and is the location of special relationships, artistic expression, and visualization.

And according to the Mayfield Clinic (brain and spine clinic) "
[n]ot all functions of the hemispheres are shared. In general, the left hemisphere controls speech, comprehension, arithmetic, and writing. The right hemisphere controls creativity, spatial ability, artistic, and musical skills. The left hemisphere is dominant in hand use and language in about 92% of people."
