Timeline of behavioral tests and USVs analysis of control and VPA rats. (A) Experimental design for behavioral tests. (B) Representative spectrograms of USVs recorded from control and VPA pups. (C) Both male (n = 12) and female (n = 15) rats in VPA group emitted fewer USVs in 5 min compared with control group (male n = 21, female n = 18). (D) Total USVs duration tended to be shorter in the VPA group of both sexes. Data are expressed as mean ± SEM, P < 0.05. Ctrl, control; USVs, ultrasonic vocalizations.
