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

• Top-down path to region: Hindbrain Metencephalon -> Cerebellar Complex (LLC.HT.CRC) -> Basilar Pontine Nuclei (LLC.HT.BPN) (see Mind Maps)
• Type: nucleus
• Quality: L0
• Brain area: Lower Brain - Locomotion Control Area (LLC)
• Area circuit: Cerebrocerebellar Locomotion (LLC)
• Role: processor.autonomic
• Function: convey information from motor cortex to cerebellum regarding intended movements of contralateral arm and leg
• Notes to function:
  • receive neocortical input and give rise to many axons that cross the midline to enter the contralateral cerebellum
