Most published sleep studies use three species: human, house mouse, or Norway rat. The degree to which data from these species captures variability in mammalian sleep remains unclear. To gain insight into mammalian sleep diversity, we examined sleep architecture in the spiny basal murid rodentAcomys cahirinus. First, we used a piezoelectric system validated forMus musculusto monitor sleep in both species. We also included wildM. musculusto control for alterations generated by laboratory-reared conditions forM. musculus. Using this comparative framework, we found thatA. cahirinus, labM. musculus,and wildM. musculuswere primarily nocturnal, but exhibited distinct behavioral patterns. Although the activity ofA. cahirinusincreased sharply at dark onset, it decreased sharply just two hours later under group and individual housing conditions. To further characterize sleep patterns and sleep-related variables, we set up EEG/EMG and video recordings and found thatA. cahirinussleep significantly more thanM. musculus, exhibit nearly three times more REM, and sleep almost exclusively with their eyes open. The observed differences inA. cahirinussleep architecture raise questions about the evolutionary drivers of sleep behavior.
