Summary

Meta-analyses demonstrate that sleep spindles, characterizing NREM sleep, may be a physiological index of high-level cognitive processes. The aim of the study is to determine if sleep spindles can predict interindividual variation in attention and cognitive performance. Relationship between attention and cognitive performance and sleep spindles characteristics (density, frequency and amplitude) recording during 1 night in 80 healthy subject (aged between 18-75y), will be calculated.

study intervention

The sleep structure of healthy volunteers will be recorded (9 Electroencephalograms (EEG), 2 Electrooculograms (EOG), 2 Electromyograms (EMG) and 2 Electrocardiograms (ECG)) during 1 night. The characteristics of the spindle (density, frequency and amplitude) will be automatically analyzed from purified EEG during Non Rapid Eye Movement sleep (NREM). Volunteers will completed a neuropsychological evaluation that will evaluate Sustained attention (simple reaction time test), Vigilance (TAP Vigilance), Sustained and selective attention (CPT II), Inhibition (Stroop test), Mental flexibility (TAP flexibility) , Executive operation (Tower of London), Short-term memory (Wechsler code test). Driving performance will be analyzed as part of a complex scenario involving attentional and high-level functions on a driving simulator.
