This page covers biological details of component group Cerebellar Complex. Component group is part of aHuman target integrated biological model.

  • Top-down path to center: Hindbrain Metencephalon -> Cerebellar Complex (LLC.HT.CRC) (see Mind Maps)
  • Function:




Component items:

  • Cerebellum (LLC.HT.CR): Motor coordination
  • Deep Cerebellar Nuclei (LLC.HT.CR.DCN)
    • Dentate Nucleus (LLC.HT.CR.DN): planning, initiation and control of voluntary movements
    • Interposed Nucleus (LLC.HT.CR.IP): coordinating agonist/antagonist muscle pairs
    • Fastigual Nucleus (LRC.HT.CR.FG): rostral - interprets body motion and places it on spatial planes to estimate movement of body through space; caudal - saccadic eye movements
  • Basilar Pontine Nuclei (LLC.HT.BPN): convey information from motor cortex to cerebellum regarding intended movements of contralateral arm and leg
