Parabrachial Nucleus

@@Home -> BiologicalLifeResearch -> BrainAreaLPC -> BrainRegionLPC_HT_PRF_PB

This page covers biological details of component Parabrachial Nucleus. Region is part of aHuman target integrated biological model.

Top-down path to region: Hindbrain Metencephalon -> Pontine Reticular Formation (HT.RF) -> Pontine Reticular Formation, Lateral Column (HT.RF.LAT) -> Parabrachial Nucleus (LPC.HT.PRF.PB) (see Mind Maps)
Type: nucleus
Brain area: Lower Brain - Peripheral Control Area
Role: relay
Function: Source of short-latency nociceptive input; sense of physiological condition of body well-being or interoception
Notes to function: major relay site for visceral afferents ascending through ventrobasal thalamus and terminating in insular cortex
