Effects of a D1 and a D2 dopamine antagonist on the self-administration of cocaine and piribedil by Rhesus monkeys

Woolverton, William L.·1986·Pharmacology Biochemistry and Behavior

Abstract

Rhesus monkeys were surgically prepared with chronic intravenous catheters and allowed to self-administer the indirect dopamine (DA) agonist cocaine (0.03 or 0.1 mg/kg/inj) or the direct D2 agonist piribedil (0.1 or 0.2 mg/kg/inj) on a fixed-ratio 10 schedule of drug delivery during daily 2 hour experimental sessions. When responding was stable, they were injected IV with SCH 23390, a selective D1 antagonist (0.003-0.3 mg/kg, 30 min pre-session) or pimozide, a selective D2 antagonist (0.003-0.3 mg/kg, 2 hours pre-session). Intermediate doses of pimozide generally increased self-administration of cocaine or piribedil, though increases in piribedil self-administration were more reliable. In contrast, intermediate doses of SCH 23390 either did not affect or decreased cocaine and piribedil self-administration. High doses of each antagonist decreased the rate of self-administration of each compound and produced catalepsy. The selective increase in responding maintained by cocaine or piribedil following pimozide pretreatment suggests a role for a D2-like receptor in psychomotor stimulant self-administration.

Recomputing p-values needs the paper’s full text.

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?

  • D2R is necessary for reward and incentive learning and maintenance of reward- and incentive-related responding, and rats will self-administer drugs that activate these receptors.

    “D2R is also necessary for reward and incentive learning, as well as maintenance of reward- and incentive-related responding, and rats will readily self-administer drugs that activate these receptors (Woolverton et al 1984; Sanger 1986; Woolverton 1986; Hoffman et al 1988; for an early review of the roles of D1R and D2R in reward and reinforcement, see Beninger et al 1989).”

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.
