Frequency modulated 50 khz ultrasonic vocalizations reflect a positive emotional state in the rat: neural substrates and therapeutic implications
the evidence that frequency modulated (FM) 50 khz ultrasonic vocalizations (USVs) reflect a positive emotional state in rats is reviewed. positive emotional states in humans are measured by facial/vocal displays (e.g., Duchenne smiling and laughter), approach behavior and subjective self-reporting of feeling states. In laboratory animals, only facial–vocal displays, along with approach behavior...
متن کاملRats concatenate 22 kHz and 50 kHz calls into a single utterance.
Traditionally, the ultrasonic vocal repertoire of rats is differentiated into 22 kHz and 50 kHz calls, two categories that contain multiple different call types. Although both categories have different functions, they are sometimes produced in the same behavioral context. Here, we investigated the peripheral mechanisms that generate sequences of calls from both categories. Male rats, either sex...
متن کاملNeurogenesis in the dentate gyrus of the rat hippocampus enhanced by tickling stimulation with positive emotion.
Hippocampal neurogenesis is influenced by many factors. In this study, we examined the effect of tactile stimulation (tickling), which induced positive emotion, on neurogenesis in the dentate gyrus (DG) of the hippocampus. Four week-old rats were tickled for 5 min/day on 5 consecutive days and received 5-bromo-2'-deoxyuridine (BrdU) administration for 4 days from the second tickling day. Then t...
متن کاملBreeding for 50-kHz positive affective vocalization in rats.
Adolescent and adult rats exhibit at least two distinct ultrasonic vocalizations that reflect distinct emotional states. Rats exhibit 22-kHz calls during social defeat, drug withdrawal, as well as in anticipation of aversive events. In contrast, 50-kHz calls are exhibited in high rates during play behavior, mating, as well as in anticipation of rewarding events. The neurochemistry of 22-kHz and...
متن کاملPharmacological analysis of 50 kHz vocalizations in the male rat
The production of 50 kHz ultrasonic vocalizations in rats has been associated with both positive social interactions and appetitive behavioural situations. Furthermore, there is significant evidence showing that these vocalizations are controlled by the meso-limbic dopamine system. The purpose of this study was to perform a pharmacological analysis of 50 kHz calls by using dopamine and two dopa...
