Document Summary
The left brain is different from the right brain. The left brain was first referred to as the dominant hemisphere due to its language functions. Researchers have now abandoned the notion of cerebral dominance in favor of models of hemispheric specialization or lateralization. Lateralization: the tendency for the right and left halves of a system to differ from one another. Each hemisphere is specialized for particular ways of working. Situs inversus: a person with a defect in one of the genes involved will develop with their organs reversed. The connections between the hemispheres ordinarily mask evidence of hemispheric specialization. Split brain individuals: an individual whose corpus callosum ahs been severed, halting communications between the right and left hemispheres. Disconnections of the cerebral hemispheres reveals their individual specializations. Split brains resulted in each hemisphere being ignorant of what the other hemisphere had just learned.
