Function
It is related to many functions via its widespread projections. The LC-NA system modulates cortical, subcortical, cerebellar, brainstem and spinal cord circuits. Some of the most important functions influenced by this system are :
Neuroplasticity
Arousal and sleep-wake cycle
Attention and memory
Emotions
Behavioral flexibility, behavioral inhibition and stress (psychological)
Posture and balance.
The locus coeruleus may figure in clinical depression, panic disorder, and anxiety. Some medications including norepinephrine reuptake inhibitors (reboxetine, atomoxetine), serotonin-norepinephrine reuptake inhibitors (venlafaxine, duloxetine), and norepinephrine-dopamine reuptake inhibitors (bupropion) are believed to show efficacy by acting upon neurons in this area.

Famous quotes containing the word function:
“The more books we read, the clearer it becomes that the true function of a writer is to produce a masterpiece and that no other task is of any consequence.”
—Cyril Connolly (1903–1974)
“Advocating the mere tolerance of difference between women is the grossest reformism. It is a total denial of the creative function of difference in our lives. Difference must be not merely tolerated, but seen as a fund of necessary polarities between which our creativity can spark like a dialectic.”
—Audre Lorde (1934–1992)
“The fact remains that the human being in early childhood learns to consider one or the other aspect of bodily function as evil, shameful, or unsafe. There is not a culture which does not use a combination of these devils to develop, by way of counterpoint, its own style of faith, pride, certainty, and initiative.”
—Erik H. Erikson (1904–1994)
