1. What does it mean for a person's brain to be "split"?
- It means that the brain is divided two hemisphere, and it is connected by the corpus callosum that transmits information between two hemisphere.

2. What was the reason why this procedure was performed on patients?
- It is because the patients did surgery which was removing a corpus callosum that connects two hemisphere. So, the brain cannot transmit information to each other. It means the brain cannot work together. It is good for this experience, because they want to know what each hemisphere does special function and two hemisphere do not work together, so researchers was able to know easily what each hemisphere does.
3. Explain one of the tests Sperry and Gazzaniga performed on these split brain patients.
- Sperry and Gazzaniga used a visual paradigm. They made that patients looked the middle point of screen, and only presented the stimulus very briefly. It was to remove participants making eye movement to left or right side of the stimuli. Second, they blindfolded patients. Then, they had patients identify objects placed in their left or right hand, and did similar things to animal.

5. What is the reason that these results occurred?
- This is because each brain parts do different works. The left brain do work related with mathematics or vocal expression. The right brain do work related with visual things such as drawing or making.

6. What is the corpus callosum and what role does it serve in your brain?
- The corpus callosum is the thick band of nerve fiebers between left hemisphere and right hemisphere. It connects both hemisphere; left and right and it allows both hemisphere to communicate to each other.
