Recognizing Words and Reading Sentences with Microsecond Flash Displays. [PDF]
PLoS ONE, 2016 Strings of dots can be used to construct easily identifiable letters, and these in turn can be used to write words and sentences. Prior work found that respondents could identify individual letters when all the dots were simultaneously flashed for an ...

FLICKER FUSION IN MULTIPLE SCLEROSIS [PDF]
Journal of Neurology, Neurosurgery & Psychiatry, 1961 This paper is concerned with a study of thresholds of critical flicker fusion frequency (C.F.F.) of a light stimulus in patients suffering from multiple sclerosis. The capacity of normal human vision to appreciate the intermittency of rapidly repeated light stimuli is a function of great physiological interest, and it may be impaired by disease at many

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

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 ...

Effect of a single dose of dextromethorphan on psychomotor performance and working memory capacity
Indian Journal of Psychological Medicine, 2012 Background: Previous studies show that the prolonged use of dextromethorphan produces cognitive deterioration in humans. Aim: The aim of this study was to investigate the effect of a single dose of dextroemthrophan on psychomotor performance and working ...

Central Beneficial Effects of Trimetazidine on Psychomotor Performance in Normal Healthy Volunteers
Advanced Biomedical Research, 2017 Background: Trimetazidine is a fatty oxidation inhibitor, leading to shifting of energy substrate from fatty acid oxidation toward glucose oxidation that leads to the reduction of oxygen requirement.
