This study investigated the multifocal fmri method for retinotopy mapping. Different from the previous studies employing m-sequence, we utilized a correlation approach to create stimulus series. This approach can be used to comprise the hemodynamic response function of BOLD effect in the generated series. In our preliminary result, we were able to acquire local signals in V1 from each of the 60 stimulated regions.
