Sleep homeostasis of a monophasic sleep in reptiles

Sleep is essential for human beings to live a healthy life and to build a healthy society. However, there are few efficient drugs or treatments for sleep disorders since the detailed neuronal mechanisms associated with sleep are unknown. In particular, monophasic sleep at night as human is less understood due to a lack of model organisms. For example, most rodents used for life science research are nocturnal and take a polyphasic sleep.
