Effects of social odor context on isolation-induced ultrasonic vocalizations (USV) emitted by BTBR T+tf/J (left) and C57BL/6J (right) mouse pups (N = 15 per strain and social odor context). (A) Total number of isolation-induced USV [n] and (B) total calling time in seconds [s] in BTBR T+tf/J and C57BL/6J mouse pups tested under clean (black) and soiled (gray) bedding conditions. (C) Call duration in milliseconds [ms], (D) peak frequency in kilohertz [kHz], (E) peak amplitude in decibel [dB], and (F) frequency modulation in kilohertz [kHz] of isolation-induced USV emitted by BTBR T+tf/J and C57BL/6J mouse pups tested under clean (black) and soiled (gray) bedding conditions. Data are presented as means ± standard errors of the mean. *p < 0.050 for soiled bedding vs. clean bedding; #p < 0.050 for BTBR T+tf/J vs. C57BL/6J mouse pups.
