Adult scent marking and open-field activity in the presence of female urine. Behavioral and ultrasonic vocalization responses to female urinary pheromones in male Shank3 mice. No genotype differences were found in number of USVs emitted in the presence of female urine (A), number of scent marks left in the arena over a 60 min acclimation period, before the introduction of female urine (B), total number of scent marks left in the arena after the acclimation period and a 5 min exposure to a drop female urine (C). D, Total distance traveled during the 5 min test was lower in −/− males than in +/+ males. +/+, N = 13; +/−, N = 12; −/−, N = 17. *p < 0.05 versus +/+. Error bars indicate SEM.
