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
