We examined the effect of sleep deprivation on self-motion perception (vection). We measured the strength of vection, its latency, and its duration in two conditions: Sleep-Deprivation and NormalSleep (by using the between-subject design). For the Sleep-Deprivation condition, participants did not sleep for about 20 hours. We also recorded subjective sleepiness with a subjective rating scale tha...

Driving Simulators reproduce situations that require tracking and visual searching, the main features of real driving. This study measured the reliability of a monotonous driving scenario to detect the circadian variations of alertness in healthy subjects. Five men and five women underwent a monotonous 30 min driving simulation task every 2 h. Before each driving task subjects completed the Sta...

The available information indicates that up to one third of the road traffic accidents are produced by the driver's sleepiness. Sleep apnea-hypopnea syndrome (SAHS) is an organic disease that causes sleepiness. It can be diagnosed by a sleep register and can be controlled by different therapeutic means, varying their complexity according to its severity, which determines the final cost of the m...

To investigate determinants of daytime sleepiness in obstructive sleep apnea syndrome (OSAS), we studied 100 unselected OSAS patients by nocturnal polygraphic recording and the Multiple Sleep Latency Test (MSLT). Data obtained were submitted to three types of analysis. Respiratory disturbance index, oxygen saturation indices, body mass index, and total nocturnal sleep time did not significantly...
