Figure 1a. Transverse summary MR images obtained at the level of the genu of the corpus callosum, just above the frontal horns of (a) the lateral ventricles and (b) the hippocampi depict all lesions summed over all subjects (lesions are yellow, cortex [mapped against the Talairach stereotaxic atlas] is blue).
