@@Home -> BiologicalLifeResearch -> BrainAreaLMC -> BrainRegionLMC_HT_LC

This page covers biological details of component Locus Coeruleus. Region is part of aHuman target integrated biological model.

  • Top-down path to region: Hindbrain Metencephalon -> Locus Coeruleus (LMC.HT.LC) (see Mind Maps)
  • Type: nucleus
  • Brain area: Lower Brain - Modulatory Contol Area
  • Role: processor.autonomic
  • Function: Regulate the intensity of responses to salient stimuli
  • Notes to function: NE Source, enhance signal-to-noise ratio, suppressing irrelevant stimuli (lateral inhibition); inhibitory nucleus
