Relationships Between Sleep Spindle and Cognitive Process in Healthy Adults

"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."
