Mesencephalic Reticular Formation

@@Home -> BiologicalLifeResearch -> BrainCenterMM_RF


This page covers biological details of component group Mesencephalic Reticular Formation. Component group is part of aHuman target integrated biological model.

  • Top-down path to center: Midbrain Mesencephalon -> Mesencephalic Reticular Formation (MM.RF) (see Mind Maps)
  • Function:
  • Notes to function: Saccades, fixation, gaze holding and vergence. Space-time coordinated rapid eye movements
