Abstract

Rodent studies suggest that prefrontal dopamine neurotransmission plays an important role in the neural processing of psychosocial stress. Human studies investigating stress-induced changes in dopamine levels, however, have focused solely on striatal dopamine transmission. The aim of this study was to investigate in vivo dopamine release in the human prefrontal cortex in response to a psychosocial stress challenge, using the highly selective dopamine D₂/₃ PET radioligand [¹⁸F]fallypride in healthy subjects. Twelve healthy subjects (age (y): 39.8; SD=15.8) underwent a single dynamic Positron Emission Tomography (PET) scanning session after intravenous administration of 185.2 (SD=10.2) MBq [¹⁸F]fallypride. Psychosocial stress was initiated at 100 min postinjection. PET data were analyzed using the linearized simplified reference region model (LSRRM), which accounts for time-dependent changes in [¹⁸F]fallypride displacement. Voxel-based statistical maps, representing specific D₂/₃ binding changes, were computed to localize areas with increased ligand displacement after task initiation, reflecting dopamine release. The psychosocial stress challenge induced detectable amounts of dopamine release throughout the prefrontal cortex, with dopaminergic activity in bilateral ventromedial prefrontal cortex being associated with subjectively rated experiences of psychosocial stress. The novel finding that a mild psychosocial stress in humans induces increased levels of endogenous dopamine in the PFC indicates that the dynamics of the dopamine-related stress response cannot be interpreted by focusing on mesolimbic brain regions alone.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Components of PNNs, such as hyaluronan and chondroitin sulfate, have antioxidant properties and can reduce generation of hydroxyl radical via chelation of transition metals and limit initiation of Haber-Weiss and Fenton's reactions.

    “Components of the PNNs, such as hyaluronan and chondroitin sulfate, have antioxidant properties (44,45) and can reduce the generation of hydroxyl radical (OH_) via their capacity to chelate transition metals and limit the initiation of Harber-Weiss and Fenton's reactions.”
  • In Gclm knockout mice with chronic glutathione deficit, a dopamine reuptake inhibitor applied during postnatal development permanently decreases the density of parvalbumin-immunoreactive cells in the anterior cingulate cortex, but not when applied in adulthood.

    “In mice with a chronic GSH deficit (Gclm KO mice, Kulak et al., 2012), administration of a dopamine re-uptake inhibitor (GBR-12909), which partially mimics dopamine release during psychosocial stress (Lataster et al., 2011) and produces ROS via the catabolism of dopamine (Cadet and Brannock, 1998; Rabinovic and Hastings, 1998), decreases permanently the density of parvalbumin-immunoreactive cells”
  • The mechanism behind psychotic stress reactivity may involve dopamine neurons being hyper-reactive to environmental stimuli and stress.

    “The biological mechanism underlying psychotic reactivity to stress could be related to hyper-reactivity of dopamine neurons to environmental stimuli and stress (Lataster et al., 2011; Mizrahi et al., 2012; Myin-Germeys et al., 2005).”

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.
