Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The two main study parameters are 1) The topography and amplitude of the evoked and spontaneous type I slow waves measured by EEG in wakefulness, NREM and REM sleep. 2) Number of mental experiences reported and features of the mental experiences (e.g. vividness) assessed with a questionnaire in RedCap. | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary study parameters are 1) Physiological arousal measures, including electrocardiographic (ECG), breathing and skin conductance, pulse wave amplitude. 2) physical arousal measured with EMG. 3) Subjective arousal measures including sleepiness, alertness and subjective perception of sleep quantity and quality during the serial awakenings and falling a sleep period. | — |
