Amphetamine-induced increases in extracellular dopamine, drug wanting, and novelty seeking: a PET/[11C] raclopride study in healthy men
Abstract
Eight healthy men underwent two positron emission tomography (PET) [11C]raclopride scans, one following placebo, the second following d-amphetamine (0.30 mg/kg, p.o.). PET data were analyzed using: (1) brain parametric maps to statistically generate regions of significant change; and (2) a priori identified regions of interest (ROI) manually drawn on each individual's co-registered magnetic resonance (MR) images. Compared with placebo, d-amphetamine decreased [11C]raclopride binding potential (BP) with significant effects in ventral but not dorsal striatum. Change in BP in the statistically generated cluster correlated with self-reported drug-induced 'drug wanting' (r = 0.83, p =.01) and the personality trait of Novelty Seeking-Exploratory Excitability (r = 0.79, p =.02). The same associations were seen in the manually drawn ROI in ventral striatum but not in dorsal putamen or caudate. Changes in extracellular dopamine (DA) did not correlate with mood. Mesolimbic DA might mediate interest in obtaining reward rather than reward, per se. Individual differences in amphetamine-induced DA release might be related to predispositions to drug and novelty seeking.

“Similarly, it is now increasingly clear that increases of human dopamine do not reliably cause enhancement of subjective ratings of pleasure (although many rewards do induce dopamine release as a consequence and correlate, but not the cause, of pleasure) (Leyton et al., 2002; Evans et al., 2006; Liggins et al., 2012).”

In the citing paper
“Dopamine surges in nucleus accumbens evoked by addictive amphetamine or by L-DOPA correlate poorly with human subjective liking ratings of the drug - but do control their subjective wanting ratings to take more of that drug (Leyton et al., 2002; Evans et al., 2006).”
From Evolving Concepts of Emotion and Motivation (2018) · cites this paper as Leyton et al., 2002
In the citing paper
“In humans, studies show that dopamine levels are more highly correlated with subjective ratings of ‘wanting’ a reward than with pleasure ratings of that same reward (Leyton et al., 2002; Volkow et al., 2002).”

“Consistent with these data, in healthy humans, amphetamine-induced dopamine changes in ventral but not dorsal striatum were found to predict hedonic responses (Drevets et al., 2001; Leyton et al., 2002; Martinez et al., 2003).”

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.
