The neural bases of spatial frequency processing during scene perception
Theories on visual perception agree that scenes are processed in terms of spatial
frequencies. Low spatial frequencies (LSF) carry coarse information whereas high spatial …

Time course of visual perception: coarse-to-fine processing and beyond
J Hegdé - Progress in neurobiology, 2008 - Elsevier
Our perception of a visual scene changes rapidly in time, even when the scene itself does

From coarse to fine? Spatial and temporal dynamics of cortical face processing
Primary vision segregates information along 2 main dimensions: orientation and spatial
frequency (SF). An important question is how this primary visual information is integrated to …

The neural substrates and timing of top–down processes during coarse-to-fine categorization of visual scenes: A combined fMRI and ERP study
Spatial frequencies in an image influence visual analysis across a distributed, hierarchically
organized brain network. Low spatial frequency (LSF) information may rapidly reach high …

[HTML][HTML] Spatial biases in viewing behavior
Viewing behavior exhibits temporal and spatial structure that is independent of stimulus
content and task goals. One example of such structure is horizontal biases, which are likely …

[HTML][HTML] The what and why of perceptual asymmetries in the visual domain
AKMR Karim, H Kojima - Advances in cognitive psychology, 2010 - ncbi.nlm.nih.gov
Perceptual asymmetry is one of the most important characteristics of our visual functioning.
We carefully reviewed the scientific literature in order to examine such asymmetries …

Brain responses to dynamic facial expressions: a normative meta-analysis
Identifying facial expressions is crucial for social interactions. Functional neuroimaging
studies show that a set of brain areas, such as the fusiform gyrus and amygdala, become …

Distinct and convergent visual processing of high and low spatial frequency information in faces
We tested for differential brain response to distinct spatial frequency (SF) components in
faces. During a functional magnetic resonance imaging experiment, participants were …

Visual and auditory alertness: modality-specific and supramodal neural mechanisms and their modulation by nicotine
Alertness is a nonselective attention component that refers to a state of general readiness
that improves stimulus processing and response initiation. We used functional magnetic …

Population spatial frequency tuning in human early visual cortex
Neurons within early visual cortex are selective for basic image statistics, including spatial
frequency. However, these neurons are thought to act as band-pass filters, with the window …
