Synopsis
We investigate the feasibility of using CBV-sensitive VASO fMRI at ultra-high field to study the selective columnar organization to axes of motion stimuli in human area MT.
For 5 subjects we found:
- BOLD and VASO both reveal characteristic tuning curves for axes of motion.
- VASO is more specific and less sensitive than BOLD.
- VASO layer profiles are less distorted by superficial veins than BOLD.
- Columnar analysis is feasible using VASO.
