I'm also a bit confused about why the dancer appears to be pictured naked. Her silhouette has plainly visible nipples. Why? How is this relevant to determining brain dominance? It seems to me that when a news story that has nothing to with nakedness calls for a picture of a person, standard procedure is to depict the person in question with clothes on. It can't even be argued that depicting her naked is supposed to make her more generic and free of any culture-specific modifications, because she has her hair up in a pony tail. Why would she bother to put her hair up but not bother to put on clothes?
Anyway, which way does she turn for you? Are you surprised by it?
