Circadian And Homeostatic Regulation Of Sleep In Cast/Eij And C57bl/6j Mice, Peng Jiang Jan 2011

Circadian And Homeostatic Regulation Of Sleep In Cast/Eij And C57bl/6j Mice, Peng Jiang

University of Kentucky Doctoral Dissertations

Sleep is essential for mammals and possibly for all animals. Advancing our knowledge of sleep regulation is crucial for the development of interventions in sleep-related health and social problems. With this aim, this study utilizes laboratory mice to explore sleep regulatory mechanisms at behavioral, molecular, and genetic levels.

Sleep is regulated by the interaction of circadian and homeostatic processes. The circadian clock facilitates sleep to occur at a favorable time of the day. Normal mice, such as the C57BL/6J (B6) strain, sleep mostly during the day and initiate activities at dark onset. Here, I show mice of the CAST/EiJ (CAST) …
