ies of a full functioning split brain, to an established professor with a belief in a cognitive theory. Gazzaniga introduces the structure of the brain and a foundation of the function and place in the evolution of the present human being. Through documented
             experiments, Gazzangia attempts to isolate the left hemisphere of the brain to examine the power of the modules and the importance of the capability of humans to infer and comprehend a variety of information.
             Gazzangia uses trial and error experiments of stimuli and response to test his hypothesis of the split brain. A brain can only be changed at an early age by altering physical properties of the brain drastically changed. A split brain is defined by the physical separation of the two cerebral hemispheres that may translate into drastic differences both social and psychologically. The split brain procedure "consisted in cutting the two main bundles of nerve fibers... the corpus callosum and the anterior commissure" (Geschwind, 181). Modules that reside in the right and left hemisphere are a complex neural system that have a particular function, that can be endlessly modified and respond to environmental affects. The genetic control of the brain determines in advance the properties and abilities of the brain. Gazzangia wished to study the way a brain organizes the information into the separate left and right hemispheres. By observing modules, he saw how certain traits of a human took action in the evolutionary scheme.
             Brain characteristics unique to humans are a distinctive trait of the individualism and powerful knowledge of the evolution of modern man, homo sapiens sapiens. A key brain structure is the corpus callosum a necessary part of human evolution and communication skills as information needs a structure to help transfer the information between the two hemispheres of the right brain and the left. The corpus callosum transfers the information so that th...
