Figure 6.
(A) After undergoing the learned helplessness (LH) paradigm, both LH and non-LH (NLH) male C57BL/6J mice underwent the female urine sniffing test (FUST) paradigm. Both the LH and NLH male C57BL/6J mice spent significantly more time sniffing estrus female urine than water (**p < .01). NLH C57BL/6J mice spent significantly longer sniffing the estrus female urine than the LH mice (*p < .05; n = 8–12). No significant differences were found between these groups for time spent sniffing the water-dipped applicator. (B) The LH and NLH C57BL/6J mice displayed significantly more ultrasonic vocalizations during exposure to urine than water in the FUST paradigm (*p < .05; n = 7).
