Science, 1959
Brown and Forsyth have recently performed a flicker-fusion experiment showing clearly that there is more to flicker than meets the eye. This report presents an analysis of their results which indicates the likelihood that at fusion threshold all but one of the Fourier components of their presentation are imperceptible.

Science, 1960
Flicker waveform has been found to have a slight but specific effect upon fusion threshold. A depression of threshold amplitude of about 30 percent occurs if a second harmonic of near-threshold amplitude is added to the fundamental. The magnitude of the depression depends critically on the relative phase of the two components of the waveform.

Flicker Fusion Thresholds in Multiple Sclerosis
Archives of Neurology And Psychiatry, 1957Problem The visual flicker-fusion threshold (FFT)* has been reported to be lower in patients with brain damage than in persons free from such pathology.1-6Most of these studies have been concerned with the effects of damage to the gray matter of the brain, especially to the frontal and occipital lobes, and the relationship of this damage to FFT.

Flicker fusion frequency in sauna-bath
Internationale Zeitschrift f�r Angewandte Physiologie Einschliesslich Arbeitsphysiologie, 1955In 20 experiments on 10 young adult male subjects the FFF was determined in connection with an exposure to high ambient temperatures in the Finnish sauna-bath. The FFF initially fell, but rose gradually back to the pre-sauna level during a 15 min. stay in the hot room. Cooling after the exposure did not cause any further changes. The FFF behaved in the

Documenta Ophthalmologica, 1964
The author reviews several phenomena occurring in sine wave flicker experiments, classifying them into low-frequency (below 10 cps) and highfrequency (above 20 cps) effects, and suggests that two different, kinds of mechanisms are needed to account for the behavior of amplitude sensitivity curves in these two frequency ranges.

Critical flicker fusion in Siamese cats
Experimental Brain Research, 1981Critical flicker fusion was determined over a wide luminance range for six Siamese and four normal cats. The Siamese cats had the lowest CFF at all luminance levels when compared to normal and binocularly deprived (BD) cats. The Siamese cat's inferior temporal resolution is most likely due to their profound y-cell loss because (1) CFF is proportional ...

Color fusion and flicker fusion frequencies using tritanopic pairs
Vision Research, 1992We determined color fusion and flicker fusion frequencies for tritanopic color pairs, so that only short wavelength sensitive cones were modulated. The minimally distinct border (MDB) technique was used to determine tritanopic pairs for each observer.

TESTING VISUAL FIELDS BY FLICKER FUSION
Archives of Neurology And Psychiatry, 1951THE CRITICAL rate at which a flickering light of decreasing frequency is first perceived to flicker is the one test of visual function in which the light-adapted eye is more sensitive at the periphery of the retina than at its center. Previous investigators have agreed that flicker fusion fields are sensitive and "typical" in neurological lesions ...
