I'm left handed for writing--language processing, right handed when throwing a ball and swinging a club--motor coordination.
As I understand it, each hemisphere of the brain is responsible for the opposing side of the body in motor functioning and sensory/perceptual processing. This doesn't hold true for language processing however as it's largely restricted to the left hemisphere; the exception to this is that left handed writers such as myself has a greater likelihood of this function taking place in the right hemisphere.I don't how this all relates to the frontal cortex, however. I think most mental illness originates in the hippocampal/limbic region of the brain which disrupts functioning in the outer regions such as the frontal cortex used for higher cognition.
As I said, writing involves mainly the language processing region largely contained in the parietal and rear frontal lobe.
