Mapping of the visual cortex: A Freesurfer™-based approach

Abstract

Retinotopy is a tool for mapping of the visual cortex which provides detailed information about the correspondence between the visual field and its cortical representation in the visual subject. Therefore, the studies about retinotopic mapping is increasing rapidly as a branch of neuro science. Our study includes three main parts: The first one is the acquiring the data. While subject is stimulated with flickering and slowly moving checkerboard, data are acquired with 3T MR machine. In the second part, analysis part, data are analyzed and visualized with Freesurfer™. Since the procedures on Freesurfer™ are complicated and depends on high technical information, in the third part, we create a MATLAB™-based GUI to make these processes simpler.
