DOI: 10.1016/j.isci.2022.103851
Abstract: Summary Visual performance has striking polar performance asymmetries: At a fixed eccentricity, it is better along the horizontal than vertical meridian and the lower than upper vertical meridian. These asymmetries are not alleviated by covert… read more here.

DOI: 10.1097/wno.0000000000000889
Abstract: A previously healthy 20-year-old man developed acute visual field loss followed by a severe headache, dizziness, and nausea that resolved after few hours. The patient presented to the emergency department 10 hours later. Ophthalmic examination… read more here.

Abstract: We recently showed that deploying attention to target stimuli displayed along the vertical meridian elicits a bilateral N2pc, that we labeled N2pcb (Psychophysiology). Here we investigated whether a different component, the sustained posterior contralateral negativity… read more here.

DOI: 10.1167/jov.21.1.2
Abstract: Human vision is heterogeneous around the visual field. At a fixed eccentricity, performance is better along the horizontal than the vertical meridian and along the lower than the upper vertical meridian. These asymmetric patterns, termed… read more here.

DOI: 10.1167/jov.23.5.6
Abstract: Temporal attention, the prioritization of information at specific points in time, improves performance in behavioral tasks but cannot ameliorate the perceptual asymmetries that exist across the visual field. That is, even after attentional deployment, performance… read more here.
