Brudzynski S, Burgdorf J, Moskal J
Brain Struct Funct
. 2024 Aug;
229(9):2327-2338.
PMID: 39096390
Emotional arousal is caused by the activity of two parallel ascending systems targeting mostly the subcortical limbic regions and the prefrontal cortex. The aversive, negative arousal system is initiated by...

Brain Sci
. 2023 Jan;
13(1).
PMID: 36672042
Cholinergic muscarinic stimulation of vast areas of the limbic brain induced a well-documented polydipsia in laboratory rats. This excessive water-drinking behavior has not received any convincing biological and physiological interpretation...

PMID: 34065107
This review summarizes all reported and suspected functions of ultrasonic vocalizations in infant and adult rats. The review leads to the conclusion that all types of ultrasonic vocalizations subserving all...

. 2019 Oct;
188:172815.
PMID: 31655084
Rats emit 22-kHz or 50-kHz ultrasonic vocalizations (USVs) to signal their emotional state to other conspecifics. The 22-kHz USVs signal a negative emotional state while 50-kHz USVs reflect a positive...

. 2019 Oct;
1726:146505.
PMID: 31605697
Behavioural sensitization of locomotion and 50 kHz ultrasonic vocalizations (USVs) following repeated amphetamine (AMPH) injections in rats has been extensively demonstrated. These two behaviours appear dissociable in their sensitization patterns...

Pharmacol Biochem Behav
. 2019 Apr;
181:77-85.
PMID: 31034853
Rats can emit 22-kHz or 50-kHz ultrasonic vocalizations (USVs) in negative, as well as positive contexts which index their emotional state. 22-kHz USVs are emitted during aversive contexts and can...

Behav Brain Res
. 2019 Jan;
364:264-273.
PMID: 30690109
Rats can produce ultrasonic vocalizations (USVs) in a variety of different contexts that signal their emotional state to conspecifics. Under distress, rats can emit 22-kHz USVs, while during positive pro-social...

. 2019 Jan;

PMID: 30677449
There is no clear relationship between crying and depression based on human neuropsychiatric observations. This situation originates from lack of suitable animal models of human crying. In the present article,...

PMID: 30444984
Systemic pharmacological manipulation of dopamine (DA) signaling has been central to many investigations of 50 kHz ultrasonic vocalizations (USVs) in the rat. In particular, the indirect DA releaser d-amphetamine (AMPH)...
