Effect of abacus training on critical flicker fusion frequency threshold among primary schoolchildren

Indian journal of physiology and pharmacology, 2021
The concept of neuronal plasticity has been considerably studied to know how long-lasting changes are associated with brain’s capacity to be shaped or sculptured by experience. Potential cognitive benefits of abacus training have been proved by various

Wavelength dependency of the critical flicker-fusion frequency: therapeutic 40 Hz light source in Alzheimer’s disease

BiOS, 2021
The use of controlled temporal modulated light increased in prominence since the LEDs invention, e.g., in computer monitors and light therapy devices. The benefits of using LEDs compared to old incandescent light bulbs range from environmental load to ...

Fundamental evaluation of mental exhaustion induced by the use of the system to provide independent views to both of eyes based on critical flicker-fusion frequency

AR, VR, MR, 2022
Humans can flexibly adapt to visual stimulation, such as spatial inversion, in which a person wears glasses that display images upside down for long periods. As with adaptation to spatial inversion, it is assumed that humans can also adapt when given the

Critical flicker-fusion frequency in age-related macular degeneration

Graefe's Archive for Clinical and Experimental Ophthalmology, 2010
To assess the influence of age-related macular degeneration (AMD) on critical flicker-fusion frequency (CFF).CFF was measured centrally for a red, green and blue target, and in 10 degrees excentricity with a red target. Twenty-eight patients with non-exsudative AMD, 12 patients with exsudative AMD and 45 age-matched healthy eyes were included.CFF ...

Analysis of flicker fusion critical frequency by the iteration method

Human Physiology, 2006
Two methods of the presentation of light stimuli for determining the flicker fusion critical frequency were compared: the classic method using a continuous increase in flicker frequency and a new iteration method in which impulses of fixed duration were presented step by step.

Critical flicker fusion frequency of the river lamprey (Lampetra fluviatilis)

Vision Research, 1979
Abstract Enucleated eyes of the river lamprey ( Lampetra fluviatilis ) were investigated by flicker stimulation. The critical fusion frequencies (CFF's) of the ERG were determined at various intensities of the stimulating light. The relation between CFF and light intensity shows two phases. On the average, the shift between these two phases occurs at

Critical Flicker Fusion Frequency: Relation to Resting Systolic Blood Pressure

Optometry and Vision Science, 2004
Past studies have shown that a number of factors, both acute and chronic, influence individual differences in critical flicker fusion frequency (CFF). In this study, we assessed whether CFF co-varied with resting systolic blood pressure (SBP).SBP and CFF were assessed in one session in 221 subjects (mean age, 19.6 +/- 2.5 years), and SBP and CFF were ...

Effect of the selected carotenoids zeaxantin and lutein on human visual processing speed, chromatic color discrimination, and critical flicker fusion frequency threshold

International Journal of Complementary & Alternative Medicine
Zeaxantin (Z) and lutein (L) are two of only three carotenoids highly concentrated in the retina of the eye as macular pigments. These also appear in the visual cortex and frontal lobe and play an essential role in visual acuity.

Critical flicker fusion frequency measurement through a chamber porthole.

Diving and Hyperbaric Medicine
The critical flicker fusion frequency (cFFF) is a non-invasive measure of central nervous system function and cortical arousal, increasingly used in diving and hyperbaric medicine to assess the effects of breathing gases under pressure.

Critical flicker fusion frequency in age‐related macular degeneration

Acta Ophthalmologica, 2008
Abstract Purpose To discuss the influence of AMD on critical flicker fusion frequency (CFF) Methods CFF was measured centrally for red, green and blue signal and in 10° excentricity with a red signal. 33 patients with non exsudative AMD and a visual acuity (VA) of 20/100‐20/20, 12 patients with exsudative AMD (VA: 20/100‐20/25) and 45 age‐matched ...
