Augmented Prefrontal Acetylcholine Release during Challenged Attentional Performance

Kozak, Rouba, Bruno, John P., Sarter, Martin·2006·Cerebral Cortex

Abstract

Previous research has demonstrated that attentional performance depends on the integrity of the cortical cholinergic input system and that such performance is associated with increases in cortical acetylcholine (ACh) release. The present experiment tested the hypothesis that the attentional impairments produced by bilateral basal forebrain infusions of the NMDA receptor antagonist DL-2-amino-5-phosphonovaleric acid (APV) are associated with attenuation of performance-associated increases in ACh release. Rats were trained in a sustained attention task and equipped with three guide cannula for the bilateral infusion of the NMDA receptor antagonist APV (0, 3, 20 nmol) and for the insertion of a dialysis probe into the medial prefrontal cortex (mPFC). APV or vehicle was infused remotely following completion of the first of five blocks of trials. During the first block, attentional performance was associated with a 140% increase in ACh efflux. Infusions of APV decreased the animals' ability to detect signals and augmented the increases in ACh efflux observed prior to infusions. These data indicate a dissociation between levels of attentional performance and increases in mPFC ACh release. Augmentation of performance-associated increases in mPFC cholinergic transmission is hypothesized to mediate the increased demands on attentional 'effort' that are required to maintain performance under challenging conditions.

  • Prefrontal muscarinic recruitment of efferent circuitry may mediate top-down effects to combat performance decay from time-on-task and distractors.

    “Such prefrontal, muscarinic recruitment of efferent circuitry may mediate top-down effects in order to, for example, combat performance decay as a result of time-on-task and other performance challenges, such as distractors (Gill et al, 2000; Kozak et al, 2006; Sarter et al, 2006).”

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.
