Requirement of central ghrelin signaling for alcohol reward
The stomach-derived hormone ghrelin interacts with key CNS circuits regulating energy balance and body weight. Here we provide evidence that the central ghrelin signaling system is required forExpand
Ghrelin increases intake of rewarding food in rodents
We investigated whether ghrelin action at the level of the ventral tegmental area (VTA), a key node in the mesolimbic reward system, is important for the rewarding and motivational aspects of theExpand
Neurobiological correlates of high (HAB) versus low anxiety-related behavior (LAB): differential Fos expression in HAB and LAB rats
BACKGROUND Two Wistar rat lines selectively bred for either high (HAB) or low (LAB) anxiety-related behavior were used to identify neurobiological correlates of trait anxiety. METHODS We used FosExpand
Evidence that the Lateral Septum is Involved in the Antidepressant-Like Effects of the Vasopressin V1b Receptor Antagonist, SSR149415
Previous experiments with the first selective nonpeptide vasopressin V1b receptor antagonist SSR149415 ((2S,Expand
Genetic predisposition to anxiety-related behavior determines coping style, neuroendocrine responses, and neuronal activation during social defeat.
Genetic background may influence an individual's susceptibility to, and subsequent coping strategy for, an acute stressor. When exposed to social defeat (SD), rats bred for high (HAB) or low (LAB)Expand
Differential roles of amygdaloid nuclei in the anxiolytic- and antidepressant-like effects of the V1b receptor antagonist, SSR149415, in rats
RationaleSSR149415 ((2S, 4R)-1-[5-chloro-1-[(2,4-dimethoxyphenyl)sulfonyl]-3-(2-methoxyphenyl)-2-oxo-2,3-dihydro-1H-indol-3-yl]-4-hydroxy-N,N-dimethyl-2-pyrrolidinecarboxamide), the first selectiveExpand
Selective blockade of NK2 or NK3 receptors produces anxiolytic- and antidepressant-like effects in gerbils
There is a growing interest in the potential anxiolytic- and antidepressant-like effects of compounds that target neurokinin receptors. Since the structure and the pharmacology of the humanExpand
Altered hypothalamo–pituitary–adrenal and sympatho-adrenomedullary activities in rats bred for high anxiety: central and peripheral correlates
Wistar rats have been selectively bred for high (HABs) or low (LABs) anxiety-related behavior based on results obtained in the elevated-plus maze. They also display robust behavioral differences in aExpand
Confinement to the open arm of the elevated-plus maze as anxiety paradigm: behavioral validation.
Exposure to the open arm of the elevated-plus maze was used to assess the neurobiological correlates of anxiety in the high-anxiety-related behavior (HAB) and low-anxiety-related behavior (LAB) ratExpand
High trait anxiety and hyporeactivity to stress of the dorsomedial prefrontal cortex: a combined phMRI and Fos study in rats
The neural basis of trait anxiety is poorly understood. In genetically selected hyperanxious (high anxiety-related behavior; HAB) rats, diazepam induces a stronger anxiolytic response than inExpand
