[HTML][HTML] Polar angle asymmetries in visual perception and neural architecture
Human visual performance changes with visual field location. It is best at the center of gaze
and declines with eccentricity, and also varies markedly with polar angle. These perceptual …

Visuospatial coding as ubiquitous scaffolding for human cognition
For more than 100 years we have known that the visual field is mapped onto the surface of
visual cortex, imposing an inherently spatial reference frame on visual information …

Linking individual differences in human primary visual cortex to contrast sensitivity around the visual field
A central question in neuroscience is how the organization of cortical maps relates to
perception, for which human primary visual cortex (V1) is an ideal model system. V1 …

Transcranial magnetic stimulation to frontal but not occipital cortex disrupts endogenous attention
A Fernández, NM Hanning… - Proceedings of the …, 2023 - National Acad Sciences
Covert endogenous (voluntary) attention improves visual performance. Human
neuroimaging studies suggest that the putative human homolog of macaque frontal eye …

Comparing retinotopic maps of children and adults reveals a late-stage change in how V1 samples the visual field
Adult visual performance differs with angular location–it is better for stimuli along the
horizontal than vertical, and lower than upper vertical meridian of the visual field. These …

Asymmetries around the visual field: From retina to cortex to behavior
Visual performance varies around the visual field. It is best near the fovea compared to the
periphery, and at iso-eccentric locations it is best on the horizontal, intermediate on the …

[HTML][HTML] The Bouma law accounts for crowding in 50 observers
JW Kurzawski, A Burchell, D Thapa… - Journal of …, 2023 - iovs.arvojournals.org
Crowding is the failure to recognize an object due to surrounding clutter. Our visual
crowding survey measured 13 crowding distances (or “critical spacings”) twice in each of 50 …

Cortical magnification eliminates differences in contrast sensitivity across but not around the visual field
Human visual performance changes dramatically both across (eccentricity) and around
(polar angle) the visual field. Performance is better at the fovea, decreases with eccentricity …

Presaccadic attention sharpens visual acuity
Visual perception is limited by spatial resolution, the ability to discriminate fine details.
Spatial resolution not only declines with eccentricity but also differs for polar angle locations …

Microsaccades and temporal attention at different locations of the visual field
H Palmieri, A Fernández, M Carrasco - Journal of vision, 2023 - jov.arvojournals.org
Temporal attention, the prioritization of information at specific points in time, improves
performance in behavioral tasks but cannot ameliorate the perceptual asymmetries that exist …
