Sleep time of pentobarbital anesthesia in different strains and sexes of mice. This basic study exemplifies how strain and gender choice can influence small animal studies. The significant differences in sleep time may be due to differential expression of metabolic enzymes. Adapted from Lovell DP. 1986. Variation in pentobarbitone sleeping time
