Experiments on split-brain patients reveal how readily the left brain interpreter can make up stories and beliefs in one experiment, for example, when the word walk was presented only to the right side of a patient’s brain, he got up and started walking. Between the split-brain patient and intact brain patient we would expect the intact brain patient to have a better performance at all the experiments it was shown that the split-brain patient and the intact brain patient had a similar outcome when it came to vocab versus reasoning 5c.
Split-brain patients have also taught us about dreaming scientists had hypothesized that dreaming is a right hemisphere activity, but they found that split brain patients do report dreaming they found, therefore, that the left hemisphere must have some access to dream material. However, the patients who underwent the operation, also called corpus callosotomy, taught the world a lot about the human brain roger sperry, a neurobiologist and a neuropsychologist, and michael gazzaniga, a graduate student in sperry’s lab were inspired by the case of the split-brain patients. Split brain is a term used to describe the result when the corpus callosum connecting the two hemispheres is severed either partially or completely before the proceeding with the surgical procedure, the patient’s head is either partially or completely shaven in order to gain easier access to the scalp. Split-brain syndrome, also called callosal disconnection syndrome, condition characterized by a cluster of neurological abnormalities arising from the partial or complete severing or lesioning of the corpus callosum, the bundle of nerves that connects the right and left hemispheres of the brain. Studies from both split-brain and hemispherectomy patients have confirmed that the brain hemispheres can operate both independently and in isolation below is a small sample of research supporting this aspect of jaynes's theory.

The 11 split-brain patients were lumped together as the experimental group, but some of the patients had experienced more deconnection than others we also cannot be sure how long each of the participants had experienced ineffective drug therapy which could have been affecting the findings. But it istrue that the daily lives of 'split-brain' patients stand in sharp contrast with their performance inlaboratory tests and defy some simple, unitary understanding of how the mind is organized in thebrain.

Research on split-brain patients led brain scientist and nobel laureate roger sperry to conclude, ‘everything we have seen indicates that the surgery has left these people with two separate. The split brain was first discovered in the laboratory by roger sperry and ronald meyers in the late 1950's initially they began experimenting with cats, and later proceeded to study monkeys in 1961 the first human patient was subject to the split brain surgery.
Classic split-brain research highlighted how the left brain and the right brain serve distinctive functions and led us to believe that the brain is a collection of modules the left brain (or hemisphere) is specialized not only for language and speech but also for intelligent behavior. By destroying the neural pathway the hemispheres of the brain are unable to communicate thereby isolating future seizure activity to one hemisphere or the other (split-brain) researchers have studied the effects of this surgical procedure on split-brain patients and the function of each hemisphere.
