Fig. 3From: Maternal sleep deprivation at different stages of pregnancy impairs the emotional and cognitive functions, and suppresses hippocampal long-term potentiation in the offspring ratsMaternal sleep deprivation increased anxiety-like behavior in the elevated plus maze task. a The offspring of ESD (n = 22), MSD (n = 18) and LSD (n = 21) spent much less time than control (n = 24) in the open arms. b The number of entry into open arms was significantly reduced in the offspring of ESD, MSD and LSD compared to control. * p < 0.05, ** p < 0.01 vs. controlBack to article page
