OK, so we're sitting around TB-East HQ (i.e. DP's office) this afternoon, trying to design an fMRI experiment with Al Braun and Nuria Abdulsabur, batting around ideas about embodied cognition (search this blog for "mirror neurons") and possible ways to test it.
Then it occurs to us--we can use secondary sex characteristics and, better yet, blatant gender stereotypes to good effect here. Forget about "lick, pick, kick" (http://www.neuron.org/content/article/abstract?uid=PIIS0896627303008389), use "shave". Then we'll see the somatosensory/motor area for faces light up in men, and the area for legs light up in women (NSFW image deleted).
Post your suggestions for additional stimuli in the comments. Best suggestion wins a Gillette Sensor (your choice: women's or men's).
