Neuroimaging research over the past 20 years has begun to reveal a
picture of how the human visual system is organized. A key distinction
that has arisen from these studies is the difference in the organization
of low-level and high-level visual regions. Low-level regions contain
topographic maps that are tightly linked to properties of the image. In
contrast, high-level visual areas are thought to be arranged in modules
that are tightly linked to categorical or semantic information in the
image. To date, an unresolved question has been how the strong
functional selectivity for object categories in high-level visual
regions might arise from the image-based representations found in
low-level visual regions. I will review recent evidence suggesting that
patterns of response in high-level visual areas may be better explained
by response to image properties that are characteristic of different
object categories.
