α 2 -Adrenergic Mechanisms in Prefrontal Cortex Associated with Cognitive Decline in Aged Nonhuman Primates

Arnsten, Amy F. T., Goldman-Rakic, Patricia S.·1985·Science

Abstract

This study provides evidence that the α 2 -adrenergic receptor agonist clonidine ameliorates the cognitive deficits exhibited by aged nonhuman primates through drug actions at α 2 receptors. Furthermore, pharmacological profiles in animals with lesions restricted to the dorsolateral prefrontal cortex indicate that this area may be the site of action for some of clonidine's beneficial effects. These results demonstrate that α-adrenergic systems contribute to cognitive function and suggest a new strategy for treating memory disorders in aged humans.

  • The beneficial effects of α2-agonists arise from stimulation of postsynaptic α2A-receptors in the PFC.

    “Although previous research focused on presynaptic receptor actions, research has established that the beneficial effects of α2-agonists arise from stimulation of postsynaptic α2A-receptors in the PFC (Arnsten and Goldman-Rakic, 1985; Cai et al., 1993).”
  • Depletion of noradrenaline or blockade of α2A-receptors in the prefrontal cortex impairs working memory, whereas stimulation of postsynaptic α2A-receptors in the prefrontal cortex improves working memory performance.

    “Thus, either depletion of noradrenaline52 or blockade of α2A-receptors in the PFC53 impairs working memory, whereas stimulation of postsynaptic α2A-receptors in the PFC improves working memory performance52,56–58.”
  • Levels of noradrenaline released during alert, non-stressed waking optimize working memory by engaging α2A-receptors, whereas high levels released during stress impair prefrontal cortex function by stimulating lower-affinity α1-receptors and β1-receptors.

    “As shown in FIG. 2, the levels of noradrenaline that are released during alert, non-stressed waking optimize working memory by engaging α2A-receptors52,53, whereas the high levels of noradrenaline that are released during stress impair PFC function by stimulating lower-affinity α1-receptors54 and β1-receptors55.”
  • Depletion of norepinephrine or blockade of α2A receptors in PFC impairs working memory performance in monkeys.

    “Either depletion of NE (35) or blockade of α2A receptors in PFC (36) impairs working memory performance in monkeys, suggesting that endogenous NE plays a large role in strengthening working memory performance.”
  • Stimulation of postsynaptic α2A receptors in dorsolateral PFC improves working memory performance.

    “Conversely, stimulation of postsynaptic α2A receptors in dorsolateral PFC, e.g., with guanfacine infusions directly into this region, improves working memory performance (35,41–43).”

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.
