In the late 1980s, researchers at the University of Parma in Italy found that the brain cells of macaque monkey fired in the same way whether they were making a particular motion (like reaching for a peanut) or watching another monkey or human make that movement.
Nicolelis and colleagues have shown that a rhesus monkey in North Carolina could, using only its brain, control the walking patterns of a robot in Japan.
There were stuffed animals, rappers, ridiculous products, bad signage filled with Engrish, booth babes stuffed into tight t-shirts, guys in Elvis costumes, guys in Kiss costumes, guys in ninja outfits, guys on skateboards, guys in monkey suits, and at least one guy wearing brain-wave controlled cat ears.
