TLDR
The activity of hypothalamic monoamines in response spontaneous feeding was investigated using the in vivo technique of brain microdialysis together with the instrumental recording of feeding pattern to suggest a possible causal relation between monoaminergic changes and behavioral initiatives.Citations

TL;DR: It is shown that in mice and rats, ghrelin bound to neurons of the VTA, where it triggered increased dopamine neuronal activity, synapse formation, and dopamine turnover in the nucleus accumbens in a GHSR-dependent manner, suggesting that the mesolimbic reward circuitry is targeted by peripheral gh Relin to influence physiological mechanisms related to feeding.
Journal ArticleDOI
Brain microdialysis and its application for the study of animal behaviour.
TL;DR: It is concluded that microdialysis is at presently the most versatile and practical method to study the chemistry of behaviour and it is to be expected that it will soon be a routine methodology in behavioural research.
Journal ArticleDOI
Behavioural and neurochemical effects induced by chronic mild stress applied to two different rat strains.
TL;DR: The results suggest that a specific and regionally differentiated serotonin-dopamine interaction is directly related to the observed stress-induced anhedonia.

Serotonin controlling feeding and satiety.
Jörg-Peter Voigt,Heidrun Fink +1 more
TL;DR: Despite the recent advances of knowledge, many of the complex interactions between 5-HT and other satiety factors are not fully understood yet.

Effects of chronic variate stress on feeding behavior and on monoamine levels in different rat brain structures.
Giovana Duzzo Gamaro,Luciana Pacheco Manoli,Iraci Lucena da Silva Torres,R. Silveira,Carla Dalmaz +4 more
TL;DR: The results suggest that emotional changes, such as exposure to stress situations can influence feeding behavior, chronic variate stress causes decreased ingestion of sweet food and decreased dopaminergic neurotransmission in hypothalamus and increased dopamine metabolite levels in the cortex and hippocampus were also observed and some of these modifications may be related to alterations in feeding behavior.

TL;DR: This paper presents a meta-analyses of the determinants of earthquake-triggered landsliding in the Czech Republic over a period of 18 months in order to establish a probabilistic framework for estimating the intensity of the earthquake.

Serotonin and appetite
TL;DR: Do results mean that some serotonin-containing neurones play a role in the natural regulatory system which serves to match an organism’s nutritional intake to its bodily requirements?

In vivo measurement of extracellular dopamine and DOPAC in rat striatum after various dopamine-releasing drugs implications for the origin of extracellular DOPAC
TL;DR: The data indicate that when the DA nerve terminal is exposed to drugs which release newly synthesized DA, DOPAC declines possibly because intraneuronal monoamine oxidase is deprived of its main substrate.

Feeding and hypothalamic stimulation increase dopamine turnover in the accumbens.
Luis Hernandez,Bartley G. Hoebel +1 more
TL;DR: The results show that perifornical LH stimulation activates the mesolimbic dopamine system and that dopamine release in the accumbens is involved in feeding, and the increase in dopamine turnover outlasted the consummatory act.
Journal ArticleDOI
Brain serotonin and eating behavior.
TL;DR: It is proposed that serotonin acts, in part, through a satiety mechanism of the medial hypothalamus, to reduce ingestion of carbohydrate while sparing protein intake, in controlling the ratio of carbohydrate to protein intake.
