In the video "Powerful Stoke of Insight," Dr. Taylor share a personal story of how she experienced when she had a stoke years ago. She vividly illustrated the distinct functions of left hemisphere and right hemisphere.

In order to create accurate data, the brain must be "normal." This means the brain must came from a healthy, productive person who has no history of psychological disorders or drug used in order to construct precise reports. Also, since not much people would willing to volunteer for the study, the sample size can be pretty small. Without a large enough sample size, the data can be limited, which the research would be
