Abstract

Vagus nerve stimulation has been used for the treatment of neuropsychiatric disorders, such as epilepsy. However, little is known whether it is also effective for the treatment of heroin dependence, in particular for relapse to heroin seeking. In the present study, we investigated the effects of vagus nerve stimulation on reinstatement (relapse) of heroin-seeking behavior induced by heroin priming or heroin-associated cues. The rats were trained for heroin self-administration for 14days and followed by extinction training in which heroin was replaced by saline and heroin-associated cues were turned off. In addition, animals were also received daily electric stimulation of vagus nerve (30Hz, pulse width of 0.5ms, 0.5mA (low-intensity) or 1mA (high-intensity); 30s on, 5min off; 10 continuous cycle per day) or false stimulation during extinction training. We found that such vagus nerve stimulation significantly inhibited heroin priming (0.25mg/kg, s.c.) - or heroin-associated conditioned cue-induced reinstatement of drug-seeking behavior, when compared to false stimulation control. Further, such a behavioral inhibition was correlated to a reduction in the expression of FosB and an increase in the expression of phosphorylation of cAMP response element binding protein (p-CREB) in nucleus accumbens. The data suggest that vagus nerve stimulation may inhibit heroin- or heroin cue-induced relapse, possibly by regulation of the expression of Fos and CREB in nucleus accumbens.

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.
