Metabolic and Cognitive Parameters Following Partial Sleep Deprivation
Sponsor: Uppsala University
Summary
The purpose of this study is to determine whether partial sleep deprivation, as compared with normal sleep, influences certain metabolic and cognitive parameters, related to food intake, hunger and memory functions, when participants are shielded from external time cues.

Conditions
Interventions
Portion Size Task
Participants are given a computer program that gives them the opportunity to choose the portions of a variety of food items that they would ideally like to consume
Blood sample
In the morning following partial sleep deprivation or normal sleep, a blood sample will be taken to assess the level of metabolism-linked and neurodegenerative-linked molecules, as well as to assay blood serum and plasma for the presence of hormones involved in hunger such as ghrelin
Interference task
30-minute interference task
Memory tasks
Participants will be allowed to learn a procedural memory task before going to bed. Participants will be retested in the morning to assess their change in performance. Other memory tests will also be given to assess the working memory performance in the morning following the intervention.
Intake task
After a normal night of sleep or partial sleep deprivation, participants are presented with an ad libitum meal choice and can select the amount to ingest during a limited time window. Amount and selection will be recorded
Working memory function task
Participants will be evaluated on their working memory performance in the morning following either nighttime intervention (NS or PSD)
