Haloperidol blocks dorsal striatum activity but not analgesia in a placebo paradigm

Abstract

Although placebo analgesia has been associated with an engagement of the endogenous opioid system there is growing evidence from neuropharmacological studies for an involvement of additional neurotransmitter systems. An increased dopaminergic neurotransmission in the ventral basal ganglia that has been found during placebo analgesia suggests a role for the dopaminergic system (Scott et al., 2007). It is, however, unclear whether striatal dopaminergic activity is causally involved in this type of analgesia. This study aimed at exploring the functional role of the dopaminergic system in placebo analgesia. To this end, we investigated the effect of the dopamine D2/D3 receptor antagonist haloperidol on behavioral and neural measures of placebo analgesia using functional magnetic resonance imaging (fMRI) in healthy volunteers. We found that 2 mg haloperidol p.o. significantly reduced the correlation between dorsal striatum activity and the individual placebo response, but had no significant effect on placebo analgesia at the behavioral or neural level, as indexed by activity in sensory or pain-modulatory brain regions. Our study therefore suggests that dopaminergic neurotransmission might not be causally involved in placebo analgesia but is related to phenomena associated with placebo analgesia such as reward processing and learning.

  • A recent study found that the ventral striatum might not be causally involved in placebo analgesia, but rather linked to phenomena associated with placebo analgesia, such as reward processing and learning.

    “This result is consistent with a recent study, in which Wrobel and colleagues (Wrobel et al., 2014) found that the ventral striatum might not be causally involved in placebo analgesia, but rather linked to phenomena associated with placebo analgesia, such as reward processing and learning.”

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.
