@@Home -> BiologicalLifeResearch -> BrainAreaLLC -> BrainRegionLLC_MM_RD_MG
This page covers biological details of component Magnocellular Part of Red Nucleus. Region is part of aHuman target integrated biological model.
- Top-down path to region: Midbrain Mesencephalon -> Red Nucleus (LLC.MM.RD) -> Magnocellular Part of Red Nucleus (LLC.MM.RD.MG) (see Mind Maps)
- Type: nucleus
- Quality: L0
- Brain area: Lower Brain - Locomotion Control Area (LLC)
- Area circuit: Spinocerebellar Locomotion (LLS)
- Role: subcortical.motor.flexor
- Function: Automatic limbs control by projection to spinal cord L6 interneurons
- Notes to function:
- excite flexors, inhibit extensors
- limb control, primarily upper limbs, but no control of fingers
- 150–200 giant or large-sized neurons in humans
- facilitating flexor alpha motor neurons and inhibiting extensor alpha motor neurons
