People are not left brain or right brain dominated. Lateralization: different parts of the brain have different functions. Right hemisphere: dominant for global spatial info. Corpus callosum: fiber of axons that connects the two hemispheres of the brain. Nerve impulses travel between two sides of brain. Split brain (severed corpus callosum) changes how patients process info. Info in left visual field processed by the right hemisphere difficulty recognizing/naming. This info is processed in the right hemisphere. Right hemisphere does not have speech capabilities; can read the word and direct the hand but can"t name.
