Our latest work on peri-saccadic vision and visual field anisotropies is now available in the Journal of Neuroscience a this link.

The paper highlights an interesting difference between anisotropies in visual perception and in the oculomotor system. While the former suggest that perception is better in the lower visual field compared to the upper one, oculomotor programming seems to follow the opposite direction, with neurons in oculomotor structures being more sensitive for the upper visual field compared to the lower.

Interestingly, in this work, we show that peri-saccadic perception follows the oculomotor system. By recording saccadic suppression in humans as index of visual perception, we observed it to be weaker for stimuli presented in the upper compared to the lower visual field. Similarly, superior colliculus (SC) neurons showed weaker suppression for stimuli presented peri-saccadically in the upper visual field!

Future work will investigate how information between these brain areas that show different type of anisotropies, e.g. V1 and SC, is achieved.
