Serotonergic modulation of reward and punishment: evidence from pharmacological fMRI studies

Macoveanu, Julian·2014·Brain Research

Abstract

Until recently, the bulk of research on the human reward system was focused on studying the dopaminergic and opioid neurotransmitter systems. However, extending the initial data from animal studies on reward, recent pharmacological brain imaging studies on human participants bring a new line of evidence on the key role serotonin plays in reward processing. The reviewed research has revealed how central serotonin availability and receptor specific transmission modulates the neural response to both appetitive (rewarding) and aversive (punishing) stimuli in putative reward-related brain regions. Thus, serotonin is suggested to be involved in behavioral control when there is a prospect of reward or punishment. The new findings may have implications in understanding psychiatric disorders such as major depression which is characterized by abnormal serotonergic function and reward-related processing and may also provide a neural correlated for the emotional blunting observed in the clinical treatment of psychiatric disorders with selective serotonin reuptake inhibitors. Given the unique profile of action of each serotonergic receptor subtype, future pharmacological studies may favor receptor specific investigations to complement present research mainly focused on global serotonergic manipulations.

  • Studies examining serotonergic drugs on reward processing in HCs revealed significant effects of both acute and prolonged treatment with drugs enhancing serotonergic transmission such as SSRIs and SNRIs and suppression of serotonergic transmission using acute tryptophan depletion.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
