| | It is very important to identify the spatial localization and retinotopy of visual areas when studying about the individual functions of the areas. Early visual areas can be mapped in vivo on the basis of fMRI retinotopy. In this study, functional scans were performed by using a 4T MRI system. It is expected that with a high magnetic field MRI system the S/N ratio will be higher and the resultant retinotopic maps more accurate. The fMRI signal was analyzed and the results were visualized on the cortical sheets. |
