; Performances of Dcx-KO male mice (n = 7 mice per genotype) expressed as the latency of the first sniff to the genital area or snout, and the total amount of time spent sniffing the genital area or the snout, measured over a 5-min period. B/Resident-Intruder; Performances of Dcx-KO (n = 17) and WT (n = 16) male mice in the resident-intruder test expressed the number of attacks, the total amount of time spent sniffing the snout, and the latency of the first anogenital sniff, and, measured over a 10-min period. Values represent means +/− SEM. *p<0.05, **p<0.01.
