@@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
  • Quality: L0
  • Brain area: Lower Brain - Peripheral Control Area (LPC)
  • Area circuit: Pain Sensations (SP)
  • Role: processor.affective
  • 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
