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

  • Top-down path to region: Midbrain Mesencephalon -> Mesencephalic Reticular Formation (MM.RF) -> Mesencephalic Reticular Formation, Midline Column (MM.RF.MID) -> Raphe Nucleus Linearis (LMC.HP.RP.LI) (see Mind Maps)
  • Type: nucleus
  • Quality: L0
  • Brain area: Lower Brain - Modulatory Contol Area (LMC)
  • Area circuit: Serotonin - Feelings of Well-Being and Happiness (5HT)
  • Role: processor.autonomic
  • Function: Release of 5-HT was only obtained on stimulation of this nucleus
  • Notes to function:
    • B8, Does not project to CR, but to forebrain, to dorsal raphe nucleus (lies above DRN)
    • dendrites to vascular plexus, maybe sensing blood pressure
