1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

1: Non-dopamine (putative GABAergic) neurons in the ventral tegmental area are in a position to influence mesolimbic functions by their inhibitory terminals that impinge locally on dopamine neurons and via their GABAergic efferents that innervate mesolimbic structures. In the present study we investigated responses of non-dopamine and dopamine neurons, recorded intracellularly in the rat midbrain slice, to orphanin FQ/nociceptin, the endogenous ligand for opioid receptor-like orphan receptors. 2: When recording in either non-dopamine or dopamine neurons, orphanin FQ/nociceptin reduced the frequency of spike firing and caused membrane hyperpolarization under current-clamp, or produced outward current under voltage-clamp. Such responses were concentration-dependent and reversed at -108 mV and -102 mV in non-dopamine and dopamine neurons, respectively. 3: Hyperpolarizations to orphanin FQ/nociceptin were not altered by tetrodotoxin or the opioid receptor antagonist naloxone, but were reduced by the opioid receptor-like orphan receptor antagonist [Phe1(1)phiCH(2)-NH)Gly(2)]NC(1-13)NH(2) (1 microM). 4: In dopamine neurons, orphanin FQ/nociceptin reduced the frequency of bicuculline- and tetrodotoxin-sensitive spontaneous inhibitory postsynaptic potentials, and reduced the amplitude of stimulus-evoked inhibitory postsynaptic potentials. 5: Taken together, the above data provide evidence that both non-dopamine and dopamine neurons are important substrates for orphanin FQ/nociceptin within the ventral tegmental area. Simultaneous inhibition of both non-dopamine and dopamine pathways by orphanin FQ/nociceptin may account for its influences on various ventral tegmental area-related functions.
