Motivational properties of opioids: evidence that an activation of σ-receptors mediates reinforcement processes

Shippenberg, T.S., Bals-Kubik, R., Herz, A.·1987·Brain Research

Abstract

The role of central delta-opioid receptors in the mediation of opioid reinforcement and endogenous reward processes was examined using a non-biased place-preference conditioning procedure. Intracerebroventricular (i.c.v.) administration of the selective delta-receptor agonist, [D-Pen2, D-Pen5]-enkephalin (DPDPE, 10.0-25.0 micrograms) produced a significant preference for the drug-associated place and a similar effect was observed following i.c.v. injections of morphine (10.0 micrograms). Administration of the delta-receptor antagonist, ICI 174,864, at doses (1.0-5.0 micrograms, i.c.v.) which had no aversive effects when tested alone, abolished the reinforcing properties of DPDPE. Such treatment did not, however, modify the effect of morphine. These findings demonstrate the involvement delta- as well as mu-receptors in the motivational properties of opioids and suggest that the activation of either receptor type is sufficient for the elicitation of appetitively reinforcing effects.

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.
