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

  • Top-down path to region: Hindbrain Metencephalon -> Metencephalic Sensory Nuclei (HT.SN) -> Pontine Nuclear Complex (HT.PN) -> Nuclei of Lateral Lemniscus (LPC.HT.PN.LL) (see Mind Maps)
  • Type: nucleus
  • Brain area: Lower Brain - Peripheral Control Area
  • Role: processor.automatic
  • Function: Decoding of amplitude modulated sounds
  • Notes to function: Prominent columnar organization, cochlea to IC
