Abstract: The retinotopic organization of the visual system in specialized visual processing areas provides an account of the resolution of visual input that is available in these areas. Given that the resolution of the visual information that is available within the parahippocampal place area is contested due to previous assumptions of its peripheral bias, we utilized Benson et al’s (2018) retinotopy dataset and the Human Connectome Project dataset to determine eccentricity and retinal field size and their anatomical organization within the parahippol campal place area. We also contrast our findings by comparing them to other specialized processing areas, namely, the fusiform face area, the occipital place area and the lateral occipital complex. We find a correlation of retinal field size and eccentricity along the anterior-posterior axis as well as a contralateral field bias across the viewing plane within each of the four regions of interest. The apparent foveal representation and spatial organization indicates that high-resolution visual information is represented within the parahippocampal place area.
