LC, LC-NE system, LC norepinephrine input

Evidence Snippets

The locus coeruleus-norepinephrine (LC-NE) system is a phylogenetically conserved neuromodulatory hub that regulates fundamental brain states and behaviors, including arousal, cognition, emotion, and pain.

Claim 1circuit functionsupports2025Source 1DOI PubMed

Specific afferent and efferent LC circuits modulate LC activity and govern diverse behaviors under physiological and disease conditions.

Quoted textsource-backed

Second, we detail the intricate connectivity of its afferent and efferent circuits, explaining how specific inputs and outputs modulate LC activity and govern diverse behaviors under physiological and disease conditions.

Claim 2evolutionary trajectorysupports2025Source 1DOI PubMed

The LC shows an evolutionary trajectory from non-mammalian to mammalian vertebrates with conserved properties and changes in cell number, anatomical projections, and physiological functions.
