.... bright light) and wavelengths (red vs. blue) affected objective (reaction time/RT) as well as subjective (sleepiness) alertness in the morning after wake-up. Methods: Participants spent two separate nights in the laboratory and were exposed to either one of the two light intensities or colors for 60 min...

... parameters of vigilance in healthy volunteers and to provide further evidence of the behavioral (subjective sleepiness, reaction time) and electrophysiological (P300 and spectral characteristics) responses to light. The results show that the short-wavelength light condition (455 nm) was found to be most...

...Andreas Konrad; Goran Vucurevic; Francesco Musso; Peter Stoeter; Georg Winterer Background: Reaction time (RT) is a frequently used measure of information processing speed, but the underlying physiological and anatomical conditions are not yet fully understood. A correlation between measures...

... including Critical Flicker Fusion (CFFT), Choice Reaction Time (CRT), tests of memory and subjective drug effects at 1, 2, 4 and 6 h after dosing. Significant improvements in CFFT and CRT were found after pyritinol. There were no significant differences on the other tests, however, the observed enhancement...

... was unaffected by glucose drinks and blood glucose levels. However, increasing blood glucose levels resulted in faster decision times when reaction time was measured. It is concluded that speed of processing is faster when the availability of glucose to the brain is increased. The possibility that the glucose...

Trickett Volunteers who develop a cold following virus challenge were significantly slower on choice reaction time tasks than those with no illness. This effect was still observed after the clinical symptoms had gone...

...Thomas Rammsayer The effects of 3 mg haloperidol and 125 mg Madopar® on duration discrimination (DD) as well as reaction times were tested in a placebo-controlled, double-blind crossover study with 24 healthy male volunteers. Performance in DD was significantly impaired under haloperidol compared...

.... Two of 4 PICD patients showed a progressive enhancement of contingent negative variation (CNV), shorter reaction time (RT) and an improvement of clinical status. The other 2 PICD patients, on the contrary, showed a progressive mild worsening of CNV-RT and clinical patterns. The double-blind trial...

...F. Lolas; I. de Andraca Peak amplitude and area under the curve of average vertex slow potentials recorded during the foreperiod of a reaction time task were found to discriminate between high- and low-neuroticism subjects, defined according to the Eysenck Personality Inventory. High-neuroticism...

...J.W. Lovett Doust; W.D. Payne; I. Podnieks Repeated measurements of reaction times were made individually in 53 healthy subjects at 60-sec intervals and continued for 30 min. The subject’s visual perceptual task each minute was to determine the momentary cessation of the second hand of a clock...

... potentials (ERPs) were then recorded with an oddball paradigm; the reaction time (RT) was measured simultaneously. According to the PSG, treatment with 0.25 mg TRZ resulted in a statistically significant increase in the percentage of stage 2 sleep (p < 0.05) and a reduction in the percentage of rapid eye...

...Giuliano Fontani; Domenico Maffei; Leda Lodi The aim of the present study was to compare the results of a 1-week, double-blind placebo-controlled trial investigating the effects of isopolicosanol and octacosanol on reactivity and related brain activity. In particular, reaction time (RT) and event...
