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

Components
(generated)
Component items:
- Mesencephalic Reticular Formation, Medial Column (MM.RF.MED)
- Cuneiform Nucleus: Passive coping strategy to novel, painful or threatening stimuli
- Subcuneiform Nucleus: Initiation of gait, feedback control of saccade accuracy
- Mesencephalic Reticular Formation, Midline Column (MM.RF.MID)
- Superior Central Raphe Nucleus: Block or temporarily suspend mnemonic processes in the hippocampus; Hallucinations
- Dorsal Raphe Nucleus: Regulation of sleep and mood
- Raphe Interpositus Nucleus: Premotor network for saccades
