Here, we draw on recent work on computational models of dopaminergic function to suggest a framework by which many of the seemingly diverse functions associated with both DA and serotonin—comprising both affective and activational ones, as well as a number of other functions not overtly related ...
impact of neuromodulators in AP showed that pharmacological manipulation of central serotonin availability via tryptophan depletion predicts AP25. This is supported by results of an impulsive choice task in the same study, akin to the critical role of serotonin in impulsivity and punishment26,27. Fol...
Memory and focus Stress response Mood Attention Digestion and blood flow Pain processing Heart rate Blood vessel function Control of nausea and vomiting Movement Dopamine vs. Serotonin Serotonin is a neurotransmitter that, like dopamine, regulates mood and other bodily functions. Both hormones increase ...
Serotonin, like dopamine (DA), has long been implicated in adaptive behavior, including decision making and reinforcement learning. However, although the two neuromodulators are tightly related and have a similar degree of functional importance, compared

Function Serotonin serves a very important role in the transmission of various nerve impulses throughout the body. The compound also has vasoconstrictor properties; meaning to say that is has the ability to narrow the blood vessels. But what is perhaps its most significant property is its ability...
Dietary Problems of Phenylketonuria: Effect on CNS Transmitters and their Possible Role in Behaviour and Neuropsychological Function Thirty years ago it was observed that the synthesis of serotonin, dopamine and norepinephrine was impaired in untreated phenylketonuria (PKU) as judged either by a decreased...
Dopamine and serotonin concentration did not exhibit high modifications by the inhibitor, suggesting the function of regulatory mechanisms or additional effect of pargyline at other sites different from monoaminooxidase. Light stimulation decreased the ratios of dopamine and its metabolites in the retina ...
Continued gambling to recover losses—‘loss chasing’—is a prominent feature of social and pathological gambling. However, little is known about the neuromodulators that influence this behavior. In three separate experiments, we investigated the role of serotonin activity, D2/D3 receptor activity,...
In fact, while the nigrostriatal system is necessary for the control of the sensory-motor coordination required for population, the mesolimbic-mesocortical system plays a key role in the preparatory phase of the behavior, mainly in sexual arousal, motivation and possibly reward. Conversely, the ...
