The effect of acute, moderate intensity indoor cycling on the temporal resolution of human vision system, measured by critical fusion frequency

open access: yesPhysiological Reports, 2020
Critical fusion frequency (CFF) reflects the basic temporal function of the visual system and therefore is a good measure of its performance. CFF has been implemented in psychological and pharmacological studies to evaluate cognitive functions.

FLICKER

open access: yesStudia Universitatis Babeș-Bolyai Philologia, 2019
Flicker. Theodore Roszak’s sophisticated and extreme long novel Flicker, published in 1991, resonates in many ways with the masterpieces of the cryptographic thriller tradition, like Umberto Eco’s Il nome della rosa (1980) or Dan Brown’s Da Vinci Code (2003). Its core lies in the conspiracy theories, due a fictional plot driven from the deep shadows of

Cone Electroretinography by Flicker [PDF]

open access: yesNature, 1951
IT is generally assumed that the b-wave of the human retinal action potential is due to the stimulation of the rods. With an intensity of 2,000 lux, the b-waves fuse at a frequency of about 20 flashes per second. At lower intensities the fusion frequency in our experiments decreased.

The ever-flickering light

open access: yesTrends in Ecology & Evolution, 2006
To date, ecologists involved in global change have focused on the consequences of changes in air temperature. Concurrently, the amount of sunlight reaching the surface of the Earth has been declining, resulting in so-called 'global dimming'. Now, Wild et al. and Pinker et al. have reported a reversal in this trend in some regions that has occurred over
