Locus Coeruleus

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
