 The visual system is the part of the central nervous system which enables human to process visual information. The visual system is divided into central and peripheral vision. Central vision prefers for fine details, whereas, peripheral vision prefers for coarser information. To well understand the perception of object in human vision system, both central and peripheral vision should be investigated together. Functional magnetic resonance imaging (fMRI) has been used for over a decade to study human visual cortex. However, visual cortex functions for the peripheral field are less well investigated because of technical difficulties in presenting large visual stimuli inside the bore of MRI scanner. We developed we developed a simple method for wide-field stimulus presentation within the MRI environment. This system is advantageous in that the presented images have high resolution. We successfully applied this visual presentation system to studies of visual retinotopic mapping, visual motion, contrast, frequency and object perception neural function in the peripheral visual field.
