Circadian rhythm study in healthy adults during wakefulness
Part of Brain & nervous system, Mental health clinical trials.
This study explores how your internal body clock and sense of time change during 36 hours of staying awake. You will stay in a lab and complete simple tasks to help researchers understand the link between circadian rhythms and time perception.
