Summary

This trial is examining how sleep patterns, reward, and cognition are linked, and how this may impact a person's risk for substance abuse.

Who is the study for?
This trial is for healthy teenagers aged 13-15 who attend a traditional high school and are not home-schooled. They must not have sleep apnea, be within a certain weight range, and cannot have serious medical conditions or a history of substance use. Those on certain medications or with MRI contraindications like metal implants can't participate.
What is being tested?
The study investigates how disrupted sleep patterns and circadian rhythms affect reward systems and cognitive control in adolescents, potentially influencing substance use risk. It involves an ultradian sleep/wake protocol to assess these effects at subjective, behavioral, and neural circuit levels.
What are the potential side effects?
Since this trial focuses on monitoring natural processes like sleep rather than testing drugs, there may be minimal side effects related to the intervention itself such as discomfort from the experimental setting or fatigue due to altered sleep patterns.

Trial Design

1Treatment groups
Experimental Treatment
Group I: Ultradian Sleep/Wake protocolExperimental Treatment1 Intervention
This study uses an ultradian sleep/wake protocol to examine circadian and homeostatic sleep systems and their contributions to reward and cognitive control function. All participants will undergo the ultradian sleep/wake protocol following a night of sleep in the lab (measured with polysomnography) for 36 hours. The ultradian sleep/wake protocol will last for 36 h, during which every 120-minutes, there will be an 80-minute period of waking, followed by a 40-minute sleep opportunity. A repeat night of sleep will occur at the end of the 36-hour ultradian sleep/wake protocol.
