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 …

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 …

Human vision has striking radial asymmetries, with performance on many tasks varying
sharply with stimulus polar angle. Performance is generally better on the horizontal than …

Asymmetries in visual performance at isoeccentric locations are well-documented and
functionally important. At a fixed eccentricity, visual performance is best along the horizontal …

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 …

With every saccadic eye movement, humans bring new information into their fovea to be
processed with high visual acuity. Notably, perception is enhanced already before a relevant …

Neurons in primate visual cortex (area V1) are tuned for spatial frequency, in a manner that
depends on their position in the visual field. Several studies have examined this …

Selectivity for many basic properties of visual stimuli, such as orientation, is thought to be
organized at the scale of cortical columns, making it difficult or impossible to measure …

Orientation selectivity in primate visual cortex is organized into cortical columns. Since
cortical columns are at a finer spatial scale than the sampling resolution of standard BOLD …

In humans and nonhuman primates, the central 1 of vision is processed by the foveola, a
retinal structure that comprises a high density of photoreceptors and is crucial for primate …
