Components
(generated)
Component items:
- Mesencephalic Reticular Formation, Medial Column (MM.RF.MED)
- Cuneiform Nucleus (LRC.MM.CNF): Passive coping strategy to novel, painful or threatening stimuli
- Subcuneiform Nucleus (LRC.MM.SCNF): Initiation of gait, feedback control of saccade accuracy
- Mesencephalic Reticular Formation, Midline Column (MM.RF.MID)
- Superior Central Raphe Nucleus (LMC.MM.RP.SUC): Block or temporarily suspend mnemonic processes in the hippocampus; Hallucinations
- Dorsal Raphe Nucleus (LMC.MM.RP.DRN): Regulation of sleep and mood
- Raphe Interpositus Nucleus (LRC.MM.RP.RIP): Premotor network for saccades
- Raphe Nucleus Linearis (LMC.HP.RP.LI): Release of 5-HT was only obtained on stimulation of this nucleus
