本研究的目的是评估卵巢激素对雌性大鼠超声发声（USV）的影响。 20 只（10 只对照和 10 只卵巢切除）3 个月大的雌性大鼠在整个动情周期或时间匹配的持续时间内以 3 种记录条件（引发、二元和隔离）进行记录。不同记录条件下的 USV 声学（频率和复杂性参数）存在差异，但对照组和卵巢切除组之间的 USV 声学没有差异。对于对照大鼠和卵巢切除大鼠，单独产生的 USV 比引发的 USV 具有更低的频率和复杂性参数。此外，对于对照大鼠，USV 参数的频率、复杂性、持续时间和强度根据动情状态而变化。因此，尽管激素水平的波动可能会影响 USV 的声学效果，但这种变化可以通过切除卵巢的雌性大鼠来控制。
The goal of this study was to evaluate the effects of ovarian hormones on female rat ultrasonic vocalizations (USVs). Twenty (10 control and 10 ovariectomized) 3-month-old female rats were recorded in 3 recording conditions (elicitation, dyad, and isolation) over a full estrous cycle or time-matched duration. There were differences in USV acoustics (frequency and complexity parameters) across recording conditions but no differences in USV acoustics between control and ovariectomized groups. USVs produced in isolation had lower frequency and complexity parameters than elicited USVs for both control and ovariectomized rats. Additionally, for control rats, USV parameters of frequency, complexity, duration, and intensity changed depending on the estrous state. Therefore, although fluctuating hormone levels may influence USV acoustics, this variation can be controlled for by ovariectomizing female rats.
