Right Hemisphere Brain Damage

Question:
If the left side of our brain is the intelect and the right side of our brain is the artistic side, then are left handed people more artistic then right handed?

Answer: No, partly because the lef brain/right brain dichotomy is not true ( Several books have been written which discuss the research evidence in more detail than popular books, and in fact the original researchers dispute the popular interpreation of their findings. )

And partly because if it was true then it would be far more likely that left-handed people had overall brain reversal. The other thing is that creativity is a higher brain function, whereas locomotor co-ordination is a lower brain function.

Not in the bull ways that women and minorities complain about, but little things that right handed people take for granted. WRITING, DESKS, SCISSORS, ETC, ETC. All of these things and many others force left handed people to use the creative parts of their brains more to be equally productive as right handers. So perhaps the dychotom of the brain is right perhaps it is wrong, I am not qualified to answer that, but I am very qualified to tell you that left handers do have certain obstacles to over come that righties do not. I am not sure though why it is that left handed people have a greater chance of being geniuses and morons and and righties have the same chance of being average.

If you are really interested check out the following articles. They are about split-brain patients. It proved that the lateralization of several cognitive abilities, shows itself by using the left or right hand. That being a fact, it is not hard to imagine that normal people also have developed 'specialized' hands. Of course contra-lateral communication is possible but there are also studies that stated that left-handed people are linguistically better able to express themselves by writing. But it doesn't only apply to the hands. Also the eyes are being influenced by the lateralization. By now, I don't think that it has fully been explored so it is not absolutely certain if it exists or not.

Investigated the left hemisphere's abilities in processing spatial information in the haptic modality. Ss were a right-handed female patient who suffered an ischemic accident resulting in damage to the anterior part of the corpus callosum and to the white matter in the posterior right hemisphere and 5 control Ss. Tasks included oral naming of haptic letters, digits, geometric shapes and 3-dimensional block letters; oral and written naming of haptic letters; haptic-visual matching of meaningless figures; letters and geometric shapes; naming letters traced on finger and palm; naming finger-guided letters; detection, naming and matching of visual letters; and naming visual letters scanned sequentially. Results indicate recognition of 2-dimensional haptic stimuli explored with the right hand was severely impaired. The deficit was not specific to the type of stimuli, since letters, digits and geometrical shapes were not correctly recognized. In contrast, the patient correctly named visual letters presented in the right visual hemifield (left hemisphere), and recognized 3-dimensional common objects palpated with the right hand.
