The clinical application of critical flicker fusion frequency in demyelinating optic neuritis [PDF]
Advances in Ophthalmology Practice and Research, 2021 Purpose: To investigate the application of critical flicker fusion frequency (CFF) in demyelinating optic neuritis (DON). Methods: A cross-sectional study. A total of 127 eyes in 69 DON patients and 63 eyes in 33 healthy control (HC) groups were included

Humans perceive flicker artifacts at 500 Hz [PDF]
Scientific Reports, 2015 Humans perceive a stable average intensity image without flicker artifacts when a television or monitor updates at a sufficiently fast rate. This rate, known as the critical flicker fusion rate, has been studied for both spatially uniform lights, and ...

Assessing the Relationship Between the Flicker Test and Cognitive Performance [PDF]
BiologyAn individual’s ability to process flickering light is expressed by critical flicker fusion frequency (CFFF), tested with the flicker test. CFFF is used to assess visual processing, arousal, and cognitive functioning, among other things, although it is ...

Orientation and Contrast Tuning Properties and Temporal Flicker Fusion Characteristics of Primate Superior Colliculus Neurons [PDF]
Frontiers in Neural Circuits, 2018 The primate superior colliculus is traditionally studied from the perspectives of gaze control, target selection, and selective attention. However, this structure is also visually responsive, and it is the primary visual structure in several species ...

Two Visual Training Paradigms Associated with Enhanced Critical Flicker Fusion Threshold [PDF]
Frontiers in Psychology, 2016 Critical flicker fusion thresholds (CFFT) describe when quick amplitude modulations of a light source become undetectable as the frequency of the modulation increases and are thought to underlie a number of visual processing skills, including reading ...

Unravelling the illusion of flicker fusion. [PDF]
Biol Lett, 2017 For over 150 years, researchers have investigated the anti-predator function of animal patterns. However, this work has mainly focused on when prey remain still, and has only recently started to incorporate motion into the study of defensive coloration.

Evaluating letter recognition, flicker fusion, and the Talbot-Plateau law using microsecond-duration flashes. [PDF]
PLoS ONE, 2015 Four experiments examined the ability of respondents to identify letters that were displayed on an LED array with flashes lasting little more than a microsecond. The first experiment displayed each letter with a single, simultaneous flash of all the dots

Visual Neuroplasticity: Modulating Cortical Excitability with Flickering Light Stimulation [PDF]
Journal of ImagingThe balance between cortical excitation and inhibition (E/I balance) in the cerebral cortex is critical for cognitive processing and neuroplasticity. Modulation of this balance has been linked to a wide range of neuropsychiatric and neurodegenerative ...
