These are not your own words plagiarizer, it's way too far outside of your normal syntax, word choice, and sentence structure:
Split brain patients presented with visual stimuli independently to each hemisphere of the brain forced the left hemisphere to create, out of whole cloth, reasoning for why the right hemisphere took an action (they were presented different unrelated stimuli in the form of pictures). When the brain is "split" (The corpus collosum is cut) the hemispheres no longer communicate. So the left hemisphere doesn't know what the right does and vice versa. But when presented with a stimulus on the right side that the left had no idea about the left side came up with an explanation for why this happened.
Correct
