In plain words

What the trial is, and whether it could suit you

Adolescence is a time of heightened reward sensitivity and greater impulsivity. On top of this, many teenagers experience chronic sleep deprivation and misalignment of their circadian rhythms due to biological shifts in their sleep/wake patterns paired with early school start times, which may increase the risk for substance use (SU). However, what impact circadian rhythm and sleep disruption either together or independently have on the neuronal circuitry that controls reward and cognition, or if there are interventions that might help to modify these disruptions is unknown. Project 1 (P1), specifically examines homeostatic and circadian characteristics as mechanisms linking habitual sleep patterns, reward and cognitive control (at subjective, behavioral, and circuit levels), and longitudinal substance use risk.
