Investigating critical flicker fusion frequency for monitoring gas narcosis in divers. [PDF]
Diving Hyperb Med, 2020 Introduction: Critical flicker fusion frequency (CFFF) has been used in various studies to measure the cognitive effects of gas mixtures at depth, sometimes with conflicting or apparently paradoxical results. This study aimed to evaluate a novel automatic CFFF method and investigate whether CFFF can be used to monitor gas-induced narcosis in divers ...

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 ...

From eyes' microtremors to critical flicker fusion. [PDF]
PLoS ONEThe critical flicker fusion threshold (CFFT) is the frequency at which a flickering light source becomes indistinguishable from continuous light. The CFFT is an important biomarker of health conditions, such as Alzheimer's disease and epilepsy, and is ...

Assessment of Alertness and Cognitive Performance of Closed Circuit Rebreather Divers With the Critical Flicker Fusion Frequency Test in Arctic Diving Conditions [PDF]
Frontiers in Physiology, 2021 Introduction: Cold water imposes many risks to the diver. These risks include decompression illness, physical and cognitive impairment, and hypothermia. Cognitive impairment can be estimated using a critical flicker fusion frequency (CFFF) test, but this

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 ...

How does cognitive function measured by the reaction time and critical flicker fusion frequency correlate with the academic performance of students? [PDF]
BMC Medical Education, 2020 Background The reaction time (RT) is “the time taken for the appearance of rapid voluntary reaction by an individual following a stimulus, either auditory or visual” and the Critical Flickering Fusion Frequency (CFFF) is “the rate at which successively ...

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 ...

Modification of Visual Critical Flicker Fusion Frequency by Intermittent Auditory Stimuli [PDF]
Nature, 1964 KRAVKOV1,2 found that visual critical flicker fusion frequency was modified by auditory stimuli, but other workers failed to confirm this3,4.
