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 -> [BrainCenterMM_PER Perhipheral Nuclei of Midbrain Mesencephalon] (MM.PER) -> [BrainRegionLPC_MM_TRH Trochlear Nucleus] (LPC.MM.TRH) (see [OverallMindMaps Mind Maps])
  * *Type*: nucleus
  * *Quality*: L0
  * *Brain area*: [BrainAreaLPC 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
