Low-Spatial-Frequency Channels and the Spatial Frequency-Doubling Illusion [PDF]
Investigative Opthalmology & Visual Science, 2009 This study examined the number and nature of spatiotemporal channels in the region where the frequency-doubling (FD) illusion would be expected to occur at eight locations spanning the central 30 degrees of the visual field.The probability of seeing the FD illusion was examined in 17 subjects.

Spatial Frequency Tuning of Body Inversion Effects
Brain Sciences, 2023 Body inversion effects (BIEs) reflect the deployment of the configural processing of body stimuli. BIE modulates the activity of body-selective areas within both the dorsal and the ventral streams, which are tuned to low (LSF) or high spatial frequencies

Spatial frequency representation in V2 and V4 of macaque monkey
eLife, 2023 Spatial frequency (SF) is an important attribute in the visual scene and is a defining feature of visual processing channels. However, there remain many unsolved questions about how extrastriate areas in primate visual cortex code this fundamental ...

Spatial mode detection by frequency upconversion [PDF]
, 2019 The efficient creation and detection of spatial modes of light has become topical of late, driven by the need to increase photon-bit-rates in classical and quantum communications. Such mode creation/detection is traditionally achieved with tools based on

Stimulus-specific mechanisms of visual short-term memory [PDF]
, 1991 The retention of spatial information in visual short-term memory was assessed by measuring spatial frequency discrimination thresholds with a two-interval forced-choice task varying the time interval between the two gratings to be compared. The memory of
