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 …

Visual attention unfolds across space and time to prioritize a subset of incoming visual
information. Distinct in key ways from spatial attention, temporal attention is a growing …

Perception and action are tightly coupled: visual responses at the saccade target are
enhanced right before saccade onset. This phenomenon, presaccadic attention, is a form of …

Covert endogenous (voluntary) attention improves visual performance. Human
neuroimaging studies suggest that the putative human homolog of macaque frontal eye …

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

Human visual performance changes dramatically both across (eccentricity) and around
(polar angle) the visual field. Performance is better at the fovea, decreases with eccentricity …

Covert spatial attention (without concurrent eye movements) improves performance in many
visual tasks (eg, orientation discrimination and visual search). However, both covert …

How do endogenous (voluntary) and exogenous (involuntary) attention modulate activity in
visual cortex? Using ROI-based fMRI analysis, we measured fMRI activity for valid and …

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 …

Orienting covert exogenous (involuntary) attention to a target location improves performance
in many visual tasks [1, 2]. It is unknown whether early visual cortical areas are necessary for …
