PBDB-T/Pentacene-Based Organic Optoelectronic Synaptic Transistor with Adjustable Critical Flicker Fusion Frequency for Dynamic Vision.

ACS Applied Materials and Interfaces
In the era of the Internet of Things and the rapid progress of artificial intelligence, there is a growing demand for advanced dynamic vision systems. Vision systems are no longer confined to static object detection and recognition, as the detection and ...

Stability of Adaptation of Critical Flicker Fusion Frequency to Intermittent Light

Nature, 1966
THE modification of critical flicker fusion frequency by intermittent light of varying frequency is unchanged by such physiological procedures as hyperventilation and rebreathing1, and by drugs2,3, which are known to alter mean critical flicker fusion frequency.

The Relationship Between Critical Flicker Fusion Frequency (CFFF) and Temperamenta Characteristics

International Journal of Occupational Safety and Ergonomics, 2000
The analysis in this paper was based on data obtained from 80 male participants, aged 29-65. Critical Flicker Fusion Frequency (CFFF) was measured using the Flicker Test. The Formal Characteristics of Behaviour Temperament Inventory (FCB-TI) by Strelau and Zawadzki (1993) was used for temperamental characteristics.

Predicting visual outcomes in keratoprosthesis surgery with critical flicker fusion frequency, B-scan, visual electrophysiology and endoscopy

British Journal of Ophthalmology
Purpose This study evaluates the predictive power of the critical flicker fusion frequency (CFF) test for visual outcomes in keratoprosthesis (KPro) candidates, comparing its accuracy with B-scan ultrasound, flash visual evoked potentials (fVEP) and ...

Efficacy of psychometric hepatic encephalopathy score versus critical flicker fusion frequency in diagnosing subclinical uremic encephalopathy in patients with chronic kidney disease – A pilot study

National Journal of Physiology Pharmacy and Pharmacology
Background: Cognitive dysfunction can occur in a significant proportion of patients with chronic kidney disease (CKD). Subclinical uremic encephalopathy (SUE) is defined as cognitive impairment (CI) greater than expected for normal aging and educational ...

An ecological correlate of critical flicker-fusion frequencies for someAnolis lizards

Vision Research, 1974
Abstract The maximum critical flicker-fusion frequency (CFF) was determined for seven species of anoline lizards. The congeners showed a wide range of CFF values from 26 to 42. These values correlated with the general level of insolation in each species' microhabitat such that the brighter the habitat, the higher the CFF.

The modification of critical flicker fusion frequency by an adapting stimulus of flickering light

Vision Research, 1965
Abstract The critical flicker fusion frequency is elevated by adaptation to intermittent light of high frequency and depressed by intermittent light of lower frequency. This relationship is almost linear between adapting frequencies of 24 and 54 c/s.

Critical flicker fusion frequency in early chloroquine retinopathy.

Canadian journal of ophthalmology. Journal canadien d'ophtalmologie, 1983
Since increasing numbers of patients with connective tissue diseases are taking chloroquine and its derivatives, there is an urgent need for a simple, reasonably fast method of screening for toxic effects on the retina. Measurement of the critical flicker fusion frequency is one technique for assessing retinal function. Its screening value was assessed

Longitudinal changes in critical flicker fusion frequency: an indicator of human workload

Ergonomics, 2005
The aim of the study was to verify a hypothesis that critical flicker fusion frequency (CFFF) is season-related because of changes in the intensity and duration of sunlight. CFFF has a wide application in different fields, generally as an indicator of human workload.

A comparison of two methods for assessing critical flicker fusion frequency in hens

Behavioural Processes, 2009
This paper compared two general methods for assessing critical fusion frequency in hens (gallus gallus domesticus). The first method was a conditional discrimination procedure with the stimuli presented successively. The second was a two-alternative forced-choice procedure with the stimuli presented simultaneously.
