Abstract: Retinotopic organization is a ubiquitous property of lowertier visual cortical areas in human and nonhuman primates. In macaque visual cortex, the retinotopic maps extend to higherorder areas in the ventral visual pathway, including area TEO in the inferior temporal (IT) cortex. Distinct regions within IT cortex are also selective to specific object categories such as faces. Here we tested the topographic relationship between retinotopic maps and face-selective patches in macaque visual cortex using high-resolution fMRI and retinotopic face stimuli.Distinct subregions within face-selective patches showed either (1) a coarse retinotopic map of eccentricity and polar
angle, (2) a retinotopic bias to a specific location of visual field, or (3) nonretinotopic selectivity. In general, regions along the lateral convexity of IT cortex showed more overlap between retinotopic maps and face selectivity, compared with regions within the STS. Thus, face patches in macaques can be subdivided into smaller patches with distinguishable retinotopic properties
