Right or Left Brain

Most people in this country likely know by now that the brain has two hemispheres, each about the size of your fist. Regardless of handedness, speech centers appear to be located in the left hemisphere only. And since the right hemisphere cannot speak, research can pose an interesting challenge. Studies by Dr. Gazzaniga reportedly used an experiment in which the right hemisphere could "talk" by using Scrabble letters. Michio Kaku included some interesting comments in his book The Future of the Mind. When a patient's left brain was asked about plans following graduation, it gave one answer while the right brain spelled out a completely different response.  Neurologist V. S. Ramanchandran reported similar results from a split-brain patient whose left hemisphere said he was an athiest while his right brain spelled out that he was a believer. Hmmm. Perhaps a given human brain is less unified in beliefs and opinions than commonly thought. Might part of your brain be Democratic and part Republican? The implications are mind-boggling!
