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:
“Nobody seriously questions the principle that it is the function of mass culture to maintain public morale, and certainly nobody in the mass audience objects to having his morale maintained.”
—Robert Warshow (1917–1955)
“No one, however powerful and successful, can function as an adult if his parents are not satisfied with him.”
—Frank Pittman (20th century)
“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)
