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:
“It is the function of vice to keep virtue within reasonable bounds.”
—Samuel Butler (1835–1902)
“Philosophical questions are not by their nature insoluble. They are, indeed, radically different from scientific questions, because they concern the implications and other interrelations of ideas, not the order of physical events; their answers are interpretations instead of factual reports, and their function is to increase not our knowledge of nature, but our understanding of what we know.”
—Susanne K. Langer (1895–1985)
“... the function of art is to do more than tell it like it is—it’s to imagine what is possible.”
—bell hooks (b. c. 1955)
