Pedunculopontine Tegmental Nuclei

@@Home -> BiologicalLifeResearch -> BrainAreaLMC -> BrainRegionLMC_HT_TG_PPN

This page covers biological details of component Pedunculopontine Tegmental Nuclei. Region is part of aHuman target integrated biological model.

  • Top-down path to region: Hindbrain Metencephalon -> Pontine Tegmental Nuclei (HT.TG) -> Pedunculopontine Tegmental Nuclei (LMC.HT.TG.PPN) (see Mind Maps)
  • Type: nucleus
  • Brain area: Lower Brain - Modulatory Contol Area
  • Role: processor.autonomic
  • Function: Provide sensory feedback to cerebral cortex; modulatory
  • Notes to function:
    • contains Rostral (Pars dissipata, anterior, dissipated subnucleus, GABA), Caudal (Pars compacta, anterior, compact subnucleus, ACh)
