Experimental: Partial sleep deprivation
Partial sleep deprivation: participants will have a 4-h sleep opportunity before a 'Blood Sample' will be taken, and the 'Memory tasks', 'Working memory function task' and 'Portion size task' will be performed.
This will be followed by an 'Interference task', followed by repeated blood sampling and an 'Intake task'.
|
Los participantes reciben un programa de computadora que les da la oportunidad de elegir las porciones de una variedad de alimentos que les gustaría consumir idealmente.
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
30-minute interference task
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.
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
Participants will be evaluated on their working memory performance in the morning following either nighttime intervention (NS or PSD)
|
|
Experimental: Normal sleep
Normal sleep: participants will have an 8-h sleep opportunity before a 'Blood Sample' will be taken, and the 'Memory tasks', 'Working memory function task' and 'Portion size task' will be performed.
This will be followed by an 'Interference task', followed with repeated blood sampling and an 'Intake task'.

Memory tasks
Periodo de tiempo: Change in memory performance between learning (at 2230 hours in NS and PSD condition) before going to sleep, and at 0800 and 0930 hours (following PSD or NS)
|
Procedural memory performance after learning a procedural memory task close to going to bed, followed by either partial sleep deprivation (PSD) or normal sleep (NS), and comparing the performance the following morning at two time points.
Participants spatial memory performance in the morning at two time points, following PSD will also be compared with that following NS, after having learned such a memory task in the evening before going to bed.

Circulating hormone levels
Periodo de tiempo: Change in circulating hormone levels and other metabolism-linked and neurodegeneration-associated molecules at 0730, 0830, 0910, 0925, 0940, 1010, 1040, 1105, and 1150 hours following the respective nighttime intervention and after the interference task

|
|
Intake task
Periodo de tiempo: Change in intake at around 1200 hours, following the respective nighttime intervention (NS or PSD)
|
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.
|
Change in intake at around 1200 hours, following the respective nighttime intervention (NS or PSD)
|
|
Working memory function task
Periodo de tiempo: Change in memory performance at 0800 hours and after the interference task again at 0930 hours (between and following PSD or NS)
|
Participants will be evaluated on their working memory performance in the morning following either nighttime intervention (NS or PSD) and before and after an interference task
|
Change in memory performance at 0800 hours and after the interference task again at 0930 hours (between and following PSD or NS)
|
|
Portion Size Task
Periodo de tiempo: Change in selected portion size from baseline (at 0800 hours following the nighttime intervention), to one hour later, i.e. after an interference task
|
Participants will be evaluated on their tendency to choose larger or smaller portions of a variety of meal items on a computer screen.
This will be conducted both following partial sleep deprivation and normal sleep, and changes before and after a short interference task will be compared between these two conditions.
|
Change in selected portion size from baseline (at 0800 hours following the nighttime intervention), to one hour later, i.e. after an interference task
