Another cluster emphasized hands instead of legs. Positive images show people with their hands clearly visible, while the negative images are exclusively non-primate animals without hands. Thus, the brain's “body” area may be made up of multiple more refined concepts (i.e. legs and hands).

Our method also identified several body-related clusters (EBA in the figure). The positive representative images for one cluster showed people and animals outside with an emphasis on legs and active movement. The negative images typically depict people sitting with their legs obscured by tables.

However, we also observed many vibrant and colorful positive images that contained no food. Strikingly, the negative representative images are entirely gray-scale! This provided very strong evidence that this brain area may be responding to color, not food.
