Experimental timeline for studying sleep and LFP changes during the virgin EST cycle, PREG, PP period and PW in female rats. The effects of mother-pup separation were also studied during the PP period. 4-h gentle handling sleep deprivation sessions were performed to study homeostatic sleep regulation during the virgin EST cycle, PREG and three consecutive thirds of the PP period. Note that the scheme shows an ideal case, some experiment lasted longer because mating session needed repetition. Furthermore, most but not all rats involved in the present study were subjected to all experiments depicted on the scheme.
