Tools of Neuroscience: MRI/fMRI

Dr. John Gabrieli of the McGovern Institute for Brain Research at MIT explains the uses of MRI (magnetic resonance imaging), which reveals the structure and function of the brain, and of the fMRI (functional magnetic resonance imaging), which shows us the changes in the brain when we engage in any activity, from moving a hand to reading a word. The fMRI essentially gives us a picture of the mind flashing across the brain.
