This study investigated the influence of social rearing on ultrasonic vocalization (USV) responses of 11- to 12-day-old rat (Rattus norvegicus) pups in isolation to the presence or removal of an anesthetized adult. Pups were reared with the dam or dam plus a virgin female (aunt), their biological sire, or a castrated male. All pups reduced rates of USV in contact with anesthetized adults. Pups' USV rates after the adult's removal depended on their rearing experience. After removal of the dam, pups increased USV rates over baseline (potentiation). Pups reared with aunts potentiated USV after contact with adult females but suppressed USV after contact with males. Pups reared with sires potentiated USV after contact with sires or strange males. Pups reared with castrated males did not suppress USV after contact with castrates but did after contact with unfamiliar intact males. Thus, pups' differential USV responses to contact with passive adults in isolation can be acquired during prior rearing experience.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D012934	Social Isolation	The separation of individuals or groups resulting in the lack of or minimizing of social contact and/or communication. This separation may be accomplished by physical separation, by social barriers and by psychological mechanisms. In the latter, there may be interaction but no real communication.

D013696	Temperature	The property of objects that determines the direction of heat flow when they are placed in direct thermal contact. The temperature is the energy of microscopic motions (vibrational and translational) of the particles of atoms.	Temperatures
D014465	Ultrasonics	A subfield of acoustics dealing in the radio frequency range higher than acoustic SOUND waves (approximately above 20 kilohertz). Ultrasonic radiation is used therapeutically (DIATHERMY and ULTRASONIC THERAPY) to generate HEAT and to selectively destroy tissues. It is also used in diagnostics, for example, ULTRASONOGRAPHY; ECHOENCEPHALOGRAPHY; and ECHOCARDIOGRAPHY, to visually display echoes received from irradiated tissues.	Ultrasonic
