Dear Doug and other Freesurferers, We are considering using rotating bowtie-shaped stimuli rather than rotating wedges for retinotopic mapping. The bowties are essentially two symmetriccal wedges, but unlike horizontal/vertical meridian mapping, they do rotate around (rather that stay at horizontal/vertical meridian).
Is Freesurfer's retinotopic mapping program capable of handling data analysis of bowtie retinotopy? Do we need to make changes to the analysis stream (e.g., when entering the number of cycles, should this be twice as frequent?) Would this mess up with color maps? Thanks for your feedback. -Yuhong ---------------------------------------------------------- Yuhong Vanessa Jiang, PhD, Department of Psychology, Univ of Minnesota jiang...@umn.edu, 612-625-7003 ----------------------------------------------------------
