1. Why is the story of Phineas Gage considered so extraordinary? What does his story teach us about the brain?
Pole struck through his skull and his brain, once recoved, the man was perfectly fine with only minor personality changes
2. (Optional) Scientists have used a drawing called a motor homunculus to show the connection between different body parts and areas of the brain. This drawing is a cartoon of the human body, where the bigger the body parts, the more area of the motor cortex that is dedicated to controlling them. If you were to draw this figure, what body parts do you think would be most exaggerated? Explain.
If I were to draw this, the body parts that would be more exaggerated would be the face and the hands since they are used the most and most controlled.
3. (Optional) How did Broca and Wernicke determine the location of key language areas in the brain?
They found the location of key language areas of the brain by examining brain damaged patients
4. (Optional) Describe one method scientists are currently using to map the function of the human brain.
One method scientists are using currently to map the function of the human brain is a MRI scan of the brain. It uses a magnetic field and pulses of radio wave energy to make pictures of radio wave energy to make pictures of organs and structures inside the body. An MRI gives different information about structures than other scanners, such as an X-ray and ultrasound. MRIs can show problems that cant be seen by other methods.
5. New research is using functional MRI (magnetic resonance imaging), a scan of the brain that shows specific areas that are activated during certain tasks, as a lie detector test. Explain which area(s) of the brain you think might light up to show that you are telling a lie or telling the truth. Explain your reasoning.
Because nerve cells require more oxygenated blood when they're busy processing information, an appropriately configured brain scan can trace
