Running Head: SPLIT BRAIN LATERALIZATION
Difference of Lateralization Between Split Brain
And Intact Brain Patients
Psychology 102 Section 6X Student
Abstract
Split brain patients lateralize functions in their brains to either side of the brains while intact brain patients utilize both sides of their brains. A group of 20 subjects were tested, 10 split brain and 10 intact brain patients. We gave these subjects three exams, a vocabulary test, a logical reasoning task and a face recognition task. We found that split brain patients have a lower correlation between these exams compared to those of an intact brain. If we were to replicate this exam we will receive roughly the same numbers, but if done so more patients to the study group will give a better understanding and better results.

And Intact Brain Patients
The purpose of this paper is to evaluate the correlational method as a means for examining the relationship between functions of the left and right hemispheres. I will compare the performance of people with intact brains with the performance of so-called split-brain patients. In many ways, the brains of these two groups are very similar. 1A. The brainstem of a normal brain is located in lower back of the brain which connects the cerebellum with the spinal cord. There is no difference between normal brainstem and a split –brain brainstem. Reason is because there is not physical cut done on the brainstem. 1B. The hippocampus is located in the limbic system structure. It is involved making, organizing and storing memories. There is no difference between a split-brain hippocampus and a normal brain hippocampus. The cut done on the corpus callosum will not affect the hippocampus because the cut would not be deep enough. 1C. The cerebral cortex of the normal brain is different from a split-brain cerebral cortex because it has not been severed. In a split-brain cerebral cortex the two
