-Scroll/click/hover around the brain to get a sense of how the Neurosynth activation map for your "other" skill differs from the map for your primary cognitive skill. In most cases, the two maps will overlap in many places, but not always. Think about the similarities and differences between the two cognitive skills, and whether these are reflected by the degree to which their functional maps overlap.+Scroll/click/hover around the brain to get a sense of how the Neurosynth activation map for your "other" skill differs from the map for your primary cognitive skill.

 +[If your two maps //really// don't overlap, you will get messages saying things like "Zero components found" for the following activities.  This happens rarely, but there are some pairs of Neurosynth maps for this assignment that do not overlap.  If, and only if, this happens to you, **you may type "my maps didn't overlap" as your answers** for Items 6, 7, 8, and 9.  You won't be penalized.]

 Now, let's do a more precise investigation of the locations where the two maps overlap. We can use Mango to define a "region of interest" (ROI) that marks all of the overlapping locations. Now, let's do a more precise investigation of the locations where the two maps overlap.
