Ultrasonic Vocalizations Induced by Sex and Amphetamine in M2, M4, M5 Muscarinic and D2 Dopamine Receptor Knockout Mice
Figure 1
Urine-induced USVs in mice were species-specific, but not strain-specific in Exp. 1.
(A) Fresh female mouse urine induced USVs in male mice, fresh female rat urine or human urine did not induce USVs in male mice. C57BL/6 mouse urine similarly induced USV in CD1 x 129 (C57–C129), vice versa (data not shown). (B) Dirty female cages induced a few USVs in male mice, and male mouse urine (second column) did not induce USVs in female mice.
