Magnetic source imaging brain map representing the localization of language. The left panel shows a brain activation map involving different language tasks superimposed on an anatomical magnetic resonance imagining scan. Note the significantly greater activation of sites in the left hemisphere versus the right hemisphere, especially in the left perisylvan region. More posterior areas of left hemisphere corresponding to Wernicke's area and the angular gyrus are also activated. In the right panel, activation of Wernicke's area is shown based on an auditory listening task.
