Ultrasonic Vocalizations in Rat and Mouse Pups
The ultrasonic vocalization (USV), or isolation calling response, of infant rats and mice has been studied as a measure of the intensity of an aversive affective state and as an early communicativeExpand

Hypothermic vocalizations of rat pups (Rattus norvegicus) elicit and direct maternal search behavior.
Emissions of ultrasonic vocalizations (USVs) by rat pups (Rattus norvegicus) during hypothermia have consequences for recovery and warming. We investigated the effects on dam behavior of USVs emittedExpand

The presence of a passive (anesthetized) littermate greatly reduced the ultrasonic vocalization of 2-wk-old rat pups placed suddenly in an unfamiliar test box, without affecting other behavior.Expand

The ontogeny of maternal potentiation of the infant rats' isolation call.
Previous studies have shown that preweanling rat pups double or triple their rates of ultrasonic vocalization (USV) when isolated immediately after brief periods of maternal interactionExpand

The Role of the Medial Prefrontal Cortex in Innate Fear Regulation in Infants, Juveniles, and Adolescents
In adult animals, the medial prefrontal cortex (mPFC) plays a significant role in regulating emotions and projects to the amygdala and periaqueductal gray (PAG) to modulate emotional responses.Expand

Relationships between maternal behavior of SHR and WKY dams and adult blood pressures of cross-fostered F1 pups.
In this experiment SHR and WKY dams reared genetically identical F1 pups derived from SHR x WKY matings. We found that a composite maternal behavior score was positively correlated with adult bloodExpand

Effects of infraorbital nerve section on survival, growth, and suckling behaviors of developing rats.
Previous studies on sensory control of nursing in the rat have emphasized local olfactory cues. This study examined the role of tactile sensory processes by surgical section of the infraorbital nerveExpand
