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 state’s one function is to give.
The bud must bloom till blowsy blown
Its petals loosen and are strown;
And that’s a fate it can’t evade
Unless ‘twould rather wilt than fade.””
—Robert Frost (1874–1963)
“The function of muscle is to pull and not to push, except in the case of the genitals and the tongue.”
—Leonardo Da Vinci (1425–1519)
“The function of literature, through all its mutations, has been to make us aware of the particularity of selves, and the high authority of the self in its quarrel with its society and its culture. Literature is in that sense subversive.”
—Lionel Trilling (1905–1975)
