The modulatory effects of nicotine on parietal cortex activity in a cued target detection task depend on cue reliability

Abstract

This functional magnetic resonance imaging study investigates the effects of nicotine in a cued target detection task when changing cue reliability. Fifteen non-smoking volunteers were studied under placebo and nicotine (Nicorette polacrilex gum 1 and 2 mg). Validly and invalidly cued trials were arranged in blocks with high, middle and low cue reliability. Two effects of nicotine were investigated: its influence on i) parietal cortex activity underlying the processing of invalid vs. valid trials (i.e. validity effect) and ii) neural activity in the context of low, middle and high informative value of the cue (i.e. cue reliability effect). Nicotine did not affect behavioral performance. However, nicotine reduced the difference in the blood oxygenation level dependent (BOLD) signal between invalid and valid trials in the right intraparietal sulcus. The reduction of parietal activity in invalid trials was smaller in the low cue reliability condition. The same posterior parietal region exhibited a nicotinic modulation of BOLD activity in valid trials which was dependent on cue reliability: Nicotine specifically enhanced the neural activity during valid trials in the context of low cue reliability, i.e. when subjects are already in a state of low certainty. We speculate that the right intraparietal sulcus might be part of two networks working in parallel: one responsible for reorienting attention and the other for the cholinergic modulation of cue reliability. By reducing the use of the cue, nicotine modulates parietal activity related to reorienting attention in conditions with higher cue certainty. On the other hand, nicotine increases parietal activity in states of low certainty. This enhanced activation might influence brain regions, such as the posterior cingulate, directly involved in the processing of cue reliability.

  • Nicotine enhanced neuronal activity in prefrontal cingulate and parietal regions specifically in trials requiring cue detection and attentional re-orienting in subjects performing a cued target detection task.

    “However, consistent with the conclusions derived from experiments in rodents, nicotine enhanced neuronal activity in prefrontal cingulate and parietal regions specifically in trials requiring cue detection and attentional re-orienting in subjects performing a cued target detection task (Giessing et al, 2006; Vossel et al, 2008).”

  • Administration of nicotine to subjects undergoing fMRI scanning did not consistently produce significant effects on cognitive performance.

    “Similar to the purely behavioral studies discussed above, administration of nicotine to subjects undergoing fMRI scanning did not consistently produce significant effects on cognitive performance (Giessing et al, 2006; Thiel and Fink, 2008; Vossel et al, 2008).”

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.
