In humans, visual information in the peripheral visual field is processed differently from such information in
the central visual field. For example, peripheral vision prefers coarser information, while central vision prefers finer details.
Recent advances in neuroimaging allowed us to non-invasively explore the neural substrates underlying the distinctiveness
of peripheral and central vision. In the human visual cortex, there is a mosaic of orderly representations of the visual
field, and this organization is called a visual field map. In this review, we summarize the various strands of research
on visual field maps, which are crucial to understand human peripheral vision. We first describe the techniques that are
used to measure visual field maps by means of functional magnetic resonance imaging (fMRI). We then review several
studies that have tried to locate human visual areas using these techniques. We focused particularly on the findings of
retinotopic organization for “far” peripheral visual field and tried to find the cortical regions that are crucial for peripheral
