Abstract

Ghosts rising off the lakeIn to moonlight In between Never so alive Norepinephrine (NE) facilitates the functioning of many brain areas, otten by increasing "signals" relative to "noise".In most brain regions, NE enhances neural processing through actions at beta and alpha-1 adrenergic receptors.This review will provide a brief overview of the receptor mechanisms influencing subcortical and posterior cortical functions and contrast these actions with the very different mechanisms by which NE modulates the working memory functions of the prefrontal cortex (PFC; Fig. 1). BETA-AND ALPHA-I-ADRENOCEPTOR STIMULATION ENHANCE POSTERIOR CORTICAL AND SUBCORTICAL FUNCTIONSNE has widespread effects on arousal state, stimulus processing, and plasticity including long-term memory consolidation.Most of these NE actions involve beta adrenergic mechanisms, although alpha-1 receptor stimulation also has important effects on excitability and cortical

  • Norepinephrine has the highest affinity for α2-receptors, with lower affinity for α1- and β-receptors.

    “Among noradrenergic receptors, NE has the highest affinity for α2-receptors, with lower affinity for α1- and β-receptors (Arnsten, 2000).”
  • Norepinephrine has the highest affinity for α2 adrenergic receptors and lower affinity for α1 and β receptors.

    “Norepinephrine has the highest affinity for α2 adrenergic receptors and lower affinity for α1 and β receptors (34).”
  • The physiological stress response, indexed by glucocorticoids and catecholamines, is related to distinct cognitive domains including declarative memory and executive functions.

    “It is also well established that the physiological response to stress, as indicated by levels of neuroendocrine hormones, glucocorticoids and catecholamines, is related to distinct aspects of cognition, including declarative memory as well as executive functions (Arnsten, 2000; Diamond, Campbell, Park, Halonen, & Zoladz, 2007).”
  • The associations are consistent with neurobiological models linking early experience with HPA axis development and stress hormones with cognition, particularly executive functions.

    “These associations are consistent with well defined neurobiological models linking early experience with the development of the HPA axis component of the stress response system (Meaney & Szyf, 2005) and linking stress and stress hormones with cognition, particularly executive functions (Arnsten, 2000; Lupien, Maheu, Tu, Fiocco, & Shramek, 2007).”
  • Norepinephrine levels shape neural responses: moderate arousal promotes prefrontal activity for reflective responses, while high levels reduce prefrontal activity and increase activity in reactive, automatized brain areas.

    “In this way, levels of NE act to influence the neural response to stimulation, promoting neural activity in PFC associated with reflective and reasoned responses to stimulation at moderate levels of arousal, whereas at high levels, NE reduces neural activity in PFC and increases neural activity in brain areas associated with reactive, automatized responses to stimulation (Arnsten, 2000).”

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.
