Locus coeruleus and amygdala

WitrynaLocus coeruleus (LC) is the major noradrenergic nucleus in the brain coexisting with endogenous opioid receptors, especially KOP and DOP (Ossipov, Dussor, & Porreca, 2010; Trang et al., 2015 ). On cessation of opioids, there is a release of GABAergic PAG-VRM inhibitory pathways and a compensatory increase in noradrenergic tone from LC. Witryna20 godz. temu · The locus coeruleus (LC) is a small region in the pons and the main source of noradrenaline (NA) to the forebrain. While traditional models suggested that all LC-NA neurons project indiscriminately throughout the brain, accumulating evidence indicates that these cells can be heterogeneous based on their anatomical …
