WebThe locus coeruleus (LC)-norepinephrine (NE) brain system is a key arousal node ; however, the function of LC-NE neurons in anesthetic emergence has been relatively understudied (6–8). The pontine nucleus LC projects NE fibers throughout the CNS and is the primary source of NE to the cerebral cortex, among other areas ( 9 ). WebNov 17, 2009 · The LC-NE system has a major role in arousal, attention, and stress response. In the brain, NE may also contribute to long-term synaptic plasticity, pain modulation, motor control, energy homeostasis, and control of local blood blow.
WebFeb 25, 2024 · Noradrenaline is a major neuromodulator in the central nervous system (CNS).
