The effect of acute sleep deprivation on visual evoked potentials in professional drivers

摘要: STUDY OBJECTIVES: Previous studies have demonstrated that as little 18 hours of sleep deprivation can cause deleterious effects on performance. It has also been suggested a "tunnel-vision" effect, in which attention is restricted to the center visual field. The current study aimed replicate these behavioral and examine electrophysiological underpinnings changes. DESIGN: Repeated-measures experimental study. SETTING: University laboratory. PATIENTS OR PARTICIPANTS: Nineteen professional drivers (1 woman; mean age = 45.3 +/- 9.1 years). INTERVENTIONS: Two sessions were performed; one following 27 other normal night sleep, with control for circadian effects. MEASUREMENTS & RESULTS: A tunnel-vision task (central versus peripheral discrimination) standard checkerboard-viewing performed while 32-channel EEG was recorded. For task, resulted an overall slowing reaction times increased errors omission both foveal stimuli (P Language: en
