Attentional effects of nicotinic agonists in rats

Abstract

Nicotine can increase stimulus detection, response rate and speed in the five-choice serial reaction time task, a rodent test of attention. In the present experiments, four other nicotinic agonists with different pharmacological profiles were compared in the same procedure. The response profile of epibatidine resembled that previously obtained with nicotine in that response accuracy was enhanced and omission errors and correct response latency decreased. ABT-418 transiently increased accuracy in the first 10 min of test sessions and reduced response latency. Isoarecolone caused a dose-related increase in accuracy, but had no effect on omissions or response latency. This absence of effects on response rate- or speed-related measures may be related to its previously reported reduced ability to release dopamine as compared with nicotine. The alpha7-agonist AR-R17779 was without effect on any measure, indicating that this receptor subtype may not mediate nicotinic effects on attention. Affinity constants of compounds, determined in competition binding assays targeting the alpha4beta2, alpha7, alpha3beta4 and alpha3beta2* nAChR subtypes, could not explain the differential behavioural effects observed. Differences in their functional efficacy at nAChR subtypes may instead be responsible. The finding that attentional performance and response rate and speed can be selectively modulated by nicotinic agonists is encouraging for the development of drugs with therapeutic properties similar to those of nicotine but with reduced unwanted 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.
