Is that a category I see before me?

An article in the Australian Broadcasting News site (gleaned from CHIWEB) talks about research to measure brain activity to measure recognition of categories in humans while browsing visual images. A team led by Dr James Haxby of the National Institute of Mental Health (NIMH) reports on the functional magnetic resonance imaging (fMRI) of the brains of six subjects, in this week's issue of Science. The team claims they can tell what category of object a person is looking at by the pattern of brain activity it produces, although an Australian expert in the area is not convinced.
