-Here is an illustration of the experiment performed by by Sperry and his colleagues for these split brain studies. After the corpus callosum connecting the two hemisphere was cut to alleviate epileptic seizures, the patients were asked to fixate on a point and name objects presented in each visual field.  Now you haven’t learned about the visual system yet, but just as sensory information from your left hand goes to your right hemisphere, visual information from the lateral part of your left visual field goes to your right visual cortex. Split brain patients could not correctly name objects presented in their left visual field, presumably because that info could not reach the left hemispheres because the callosal connections were severed. But split brain patients could correctly name an object when presented in their right visual field, because that information was received by the left visual cortex and could be passed onto the language centers.

 In all Sperry and his colleagues showed that language, mathematical, and logical reasoning is dominant in the left hemisphere and that shape recognition, spatial attention, emotional processing, and creativity in more dominant in the right hemisphere.

+Babbling sounds from a baby shows that there is a pattern of sounds produced sequentially that are related to the phones necessary for producing spoken language. Language imitation follows other imitations (mirror neurons?) during developmental learning and behavioral acquistion. Brain is continuously simulating the future based on past experienced training patterns.
