The role of the GABAergic system in the production of ultrasonic vocalization in rats /
Ultrasonic vocalization plays an important role in intraspecies communication for rats. It has been well demonstrated that rats will emit 22kHz vocalization in stressfiil or threatening situations. Although the neural mechanism underlying vocahzation is not well understood, it is known that …

INTRACRANIAL INFUSIONS OF NEUROTENSIN AGONISTS PRODUCE AN ANXIOLYTIC PROFILE IN A RAT ULTRASONIC VOCALIZATION MODEL
… can attenuate the number of fear-induced 22-kHz ultrasonic vocalizations (USVs) produced by male Wistar rats. A reduction in the number of 22-kHz USV calls is indicative of an anxiolytic effect. The current study used a USV model to evaluate the effects of PD149163 (0.1, 1.0, and 10.0 ng) and …

Immunohistochemical study of laterodorsal tegmental neurons active during 22kHz vocalization /
… (LDT), was implicated in the initiation of ultrasonic vocalization. The goal of this study was to histochemically examine the activity the LDT following ultrasonic calls induced by two methods. It was hypothesized that cholinergic LDT cells would be more active during air puffinduced …

Interactions between the cholinergic and dopaminergic system during the production of ultrasonic vocalizations in rats
Rats produce ultrasonic vocalizations that can be categorized into two types of ultrasonic calls based on their sonographic structure. One group contains 22-kHz ultrasonic vocalization (USVs), characterized by relatively constant (flat) frequency with peak frequency ranging from 19 to 28-kHz, and a …

Analysis of the expression and effects of vascular endothelial growth factor family of molecules on Fragile X Syndrome abnormalities in a mouse model
… al., 2017). Chapter 4 explored and characterized ultrasonic vocalization (USV) abnormalities in FXS mice to find more human relevant behavioral metrics to assess potential therapeutic interventions (Belagodu et al., 2016). Utilizing these studies, Chapter 5 assessed the extent to which blocking …

Influence of Mouse Motor Cortex on Vocal Musculature
… vertebrates share common brainstem circuits for vocalization, and they produce innate vocal repertoires over which the animals have little to no control. Vocal learners can imitate heard sounds, and thus have a high degree of control over their vocalizations. Vocal learning species have a direct …

ONTOGENY AND NEURAL MECHANISMS OF VOCAL COMMUNICATION IN MUS MUSCULUS
Innate vocalizations play a critical communicative role for both human and non-human animals. Infants of altricial species vocalize when hungry, cold, or isolated from caregivers and their nest environment. These ‘infant vocalizations’ are crucial for the survival of altricial infants, including …
