Flicker fusion thresholds as a clinical identifier of a magnocellular-deficit dyslexic subgroup [PDF]
Scientific Reports, 2020 The magnocellular-dorsal system is well isolated by high temporal frequency. However, temporal processing thresholds have seldom been explored in developmental dyslexia nor its subtypes.

Gamma flicker triggers attentional selection without awareness [PDF]
, 2009 Gamma band modulations in neural activity have been proposed to mediate attentional processes. To support a causal link between gamma activity and attentional selection, we attempt to evoke gamma oscillations by a 50-Hz subliminal flicker. We find that a

International Journal of Environmental Health Engineering, 2023 Aim: Undesirable lighting can affect the visual system, as well as mental, neuropsychological, and physiological efficiency of staff. The present study was done to determine the effect of luminosity and nominal correlated color temperature (NCCT) on the ...

A new diagnostic approach in Alzheimer's disease: The critical flicker fusion threshold [PDF]
Dementia & Neuropsychologia, 2022 . Alzheimer's disease (AD) is the most common cause of dementia in the elderly. Although AD treatment is still insufficient despite all the recent developments, detection and treatment in the early stage of disease have provided more clinical benefits ...

How long depends on how fast--perceived flicker dilates subjective duration.
PLoS ONE, 2013 How do humans perceive the passage of time and the duration of events without a dedicated sensory system for timing? Previous studies have demonstrated that when a stimulus changes over time, its duration is subjectively dilated, indicating that duration

Core size effects of laser fusion subcritical research reactor for fusion engineering research [PDF]
, 2021 A multi-purpose high repetition laser facility, the so-called Japan establishment for power-laser community harvest (J-EPoCH) is proposed as a next generation laser facility. J-EPoCH will operate at the maximum rate of 100 Hz.

Frontiers in Aging Neuroscience, 2019 As the visual system ages, flicker sensitivity decreases and the latencies of cortical visual evoked potentials (VEP) increase. However, the extent to which these effects reflect age-related changes in the magnocellular (M) and or parvocellular (P ...

A gaze on luminance flicker stimulation [PDF]
, 2023 openLa stimolazione luminosa con flicker (FLS), o stimolazione fotica intermittente (IPS), viene definita da Allefeld e collaboratori (2011) come “un metodo non farmacologico, in grado di causare varie esperienze soggettive non controllabili ...

The speed of sight: Individual variation in critical flicker fusion thresholds.
PLoS ONEThe critical flicker fusion threshold is a psychophysical measure commonly used to quantify visual temporal resolution; the fastest rate at which a visual system can discriminate visual signals. Critical flicker fusion thresholds vary substantially among
