Abstract: Visual area V4 is a midtier cortical area in the ventral visual pathway. It is crucial for visual object recognition
and has been a focus of many studies on visual attention. However, there is no unifying view of V4’s role in
visual processing. Neither is there an understanding of how its role in feature processing interfaces with its
role in visual attention. This review captures our current knowledge of V4, largely derived from electrophysiological
and imaging studies in the macaque monkey. Based on recent discovery of functionally specific
domains in V4, we propose that the unifying function of V4 circuitry is to enable selective extraction of specific
functional domain-based networks, whether it be by bottom-up specification of object features or by topdown
attentionally driven selection.
