This page covers biological details of component Trochlear Nucleus. Region is part of aHuman target integrated biological model.
- Top-down path to region: Midbrain Mesencephalon -> Perhipheral Nuclei of Midbrain Mesencephalon (MM.PER) -> Trochlear Nucleus (LPC.MM.TRH) (see Mind Maps)
- Type: nucleus
- Quality: L0
- Brain area: Lower Brain - Peripheral Control Area (LPC)
- Area circuit: Vision Motor (AVM)
- Role: flexor.nucleus
- Function: Control superior oblique muscles of eyes
- Notes to function:
- Muscle nucleus, change eye direction
