studyforrest.org: Multi-resolution 7T fMRI on visual orientation representation [BIDS] Here we presentcempirical ultra high-field fMRI data recorded at four spatial resolutions (0.8 mm, 1.4 mm, 2 mm, and 3 mm isotropic voxel size) for orientation decoding in visual cortex — in order to test hypotheses on the strength and spatial scale of orientation discriminating signals. The entire dataset and the analysis codes presented in BIDS (Brain Imaging Data Structure).
