 Abstract: The superior colliculus (SC) is a layered structure involved in visual and multisensory control. Due to its small size and location it is challenging to evaluate its function with the conventional MR fields. In this study we compare the depth-dependence of visual signals in SC for 9.4T and 3T data. The highest signal was observed in the superficial zone of the superior colliculus (for both datasets). However, the increase in sensitivity in the blood oxygen level dependent size allowed us to get higher response lateralization and a significative higher depth-dependence of visual signals in the 9.4T.
