Ten percent of the brain myth 20th century. For example, the functions of many brain regions (especially in the cerebral cortex) are complex enough that the effects of damage are subtle, leading early neurologists to wonder what these regions did. The brain was also discovered to consist mostly of glial cells, which seemed to have very minor functions. James W. Kalat, author of the textbook "Biological Psychology", points out that neuroscientists in the 1930s knew about the large number of "local" neurons in the brain. The misunderstanding of the function of local neurons may have led to the ten percent myth. The myth might have been
The Boston process approach the outcomes to make conclusions on what is going on in the brain. These conclusions are based on the errors that occurred during the test. The point of looking at the errors is to see what issues may have occurred when trying to process the information and answer the question in order to evaluate the specific deficit(s). Certain inaccuracies may infer that there’s damage to a definite part of the brain, like speech difficulties implicating the speech area in the left hemisphere. The qualitative analysis focuses on closely observing the process by which a patient arrives at a final answer.
