Sleep, Circadian and Other Rhythm Experiments Core

Equipment/facility: Facility


The Sleep, Circadian and Other Rhythm Experiments (SCORE) Core's fundamental mission is to advance our understanding of rhythms in health and disease. The Core will be dedicated to supporting research of sleep, circadian, gene expression, endocrine, behavioral, and reproductive rhythms in rodent models. Equipment, experimental housing, and experienced personnel are available to carry out a wide range of experimental designs. The Core will also offer training and consulting in experimental design and data analysis of rhythm studies.
