原始语种摘要: This study examined low‑frequency ultrasonic vocalizations (lUSVs) in rats during two types of sexual interactions; postejaculatory interval (PEI) and barrier – noncontact (NC) test. We report distinct classes of lUSVs that can be assigned to different emotional states; relaxation vs. frustration. Totally flat, 22‑kHz calls (Class A), were observed during the relaxation state following ejaculation; characterized by immobilization or grooming during the PEI. On the other hand, two‑three component lUSVs (Class B) that start at a higher frequency (45‑kHz: flat, upward or short signal) and then shift to 35–23‑kHz (mostly to 28‑23‑kHz), correspond as we assume, to arousal and frustration – active states associated with sniffing a hole or exploration during the NC test. We suggest that...
