Zaretskaya et al. (2020) investigated the detectability of ocular dominance signals using high-resolution functional magnetic resonance imaging (fMRI). Here, 9.4-tesla fMRI and 3-tesla fMRI were compared. The detection of selectivity for eye dominance signals in area V1 using high resolution (9.4 Tesla fMRI) proved to be more reliable than under lower resolution (3-Tesla). In addition, analyses of cortical depth showed a stronger eye dominance in the cortical surface area. However, the measurement of eye dominance signals using the GE-EPI method at 9 Tesla seems to be more influenced by vascular than neural effects.
