Cortical distinction between the neural encoding of objects that appear to glow and those that do not.
Objects that appear to glow appear very different from those that do not. However, the neural representation of glow has not been investigated. We present data from an fMRI study which suggest that an extra-striate visual area is involved in the encoding of glowing stimuli, and that this activation does not arise from luminance or contrast factors. Possible functional reasons for the existence of such an area are discussed.
