[HTML][HTML] Polar angle asymmetries in visual perception and neural architecture

MM Himmelberg, J Winawer, M Carrasco - Trends in Neurosciences, 2023‏ - cell.com
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 …

Linking individual differences in human primary visual cortex to contrast sensitivity around the visual field

MM Himmelberg, J Winawer, M Carrasco - Nature communications, 2022‏ - nature.com
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 …

[HTML][HTML] Asymmetries in visual acuity around the visual field

A Barbot, S Xue, M Carrasco - Journal of vision, 2021‏ - arvojournals.org
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 …

Comparing retinotopic maps of children and adults reveals a late-stage change in how V1 samples the visual field

MM Himmelberg, E Tünçok, J Gomez… - Nature …, 2023‏ - nature.com
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 …

[HTML][HTML] Stimulus-dependent contrast sensitivity asymmetries around the visual field

MM Himmelberg, J Winawer, M Carrasco - Journal of vision, 2020‏ - iovs.arvojournals.org
Asymmetries in visual performance at isoeccentric locations are well-documented and
functionally important. At a fixed eccentricity, visual performance is best along the horizontal …

[HTML][HTML] Cross-dataset reproducibility of human retinotopic maps

MM Himmelberg, JW Kurzawski, NC Benson, DG Pelli… - Neuroimage, 2021‏ - Elsevier
Population receptive field (pRF) models fit to fMRI data are used to non-invasively measure
retinotopic maps in human visual cortex, and these maps are a fundamental component of …

Presaccadic attention sharpens visual acuity

Y Kwak, NM Hanning, M Carrasco - Scientific Reports, 2023‏ - nature.com
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 …

Variability of the surface area of the V1, V2, and V3 maps in a large sample of human observers

NC Benson, JMD Yoon, D Forenzo, SA Engel… - Journal of …, 2022‏ - jneurosci.org
How variable is the functionally defined structure of early visual areas in human cortex and
how much variability is shared between twins? Here we quantify individual differences in the …

Cortical magnification eliminates differences in contrast sensitivity across but not around the visual field

M Jigo, D Tavdy, MM Himmelberg, M Carrasco - elife, 2023‏ - elifesciences.org
Human visual performance changes dramatically both across (eccentricity) and around
(polar angle) the visual field. Performance is better at the fovea, decreases with eccentricity …

Asymmetries around the visual field: From retina to cortex to behavior

ER Kupers, NC Benson, M Carrasco… - PLoS computational …, 2022‏ - journals.plos.org
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 …
