Abstract

Norepinephrine (NE) has widespread projections throughout the brain, and thus, is ideally positioned to orchestrate neural functions based on arousal state. For example, NE can increase "signal/noise" ratio in the processing of sensory stimuli, and can enhance long-term memory consolidation in the amygdala and hippocampus through actions at alpha-1 and beta adrenoceptors. Over the last 20 years, NE has also been shown to play a powerful role in regulating the working memory and attention functions of the prefrontal cortex (PFC). Moderate levels of NE released under control conditions strengthen prefrontal cortical functions via actions at post-synaptic alpha-2A adrenoceptors with high affinity for NE, while high levels of NE release during stress impair PFC cortical functions via alpha-1 and possibly beta-1 receptors with lower affinity for NE. Thus, levels of NE determine whether prefrontal cortical or posterior cortical systems control our behavior and thought. Understanding these receptor mechanisms has led to new intelligent treatments for neuropsychiatric disorders associated with PFC dysfunction.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • As neurochemicals rise beyond moderate levels, prefrontal cortex activity is reduced and activity increases in brain areas associated with reactive motoric and emotional-motivational responses.

    “As these neurochemicals continue to rise beyond a moderate level, however, activity in PFC is reduced and activity is increased in brain areas associated with reactive motoric and emotional-motivational responses to stimulation”

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.
