Rostral Interstitial Nucleus Of Mlf plays an important role in the study of neurodegenerative diseases. This page provides comprehensive information about this topic, including its mechanisms, significance in disease processes, and therapeutic implications.
Introduction
The rostral interstitial nucleus of the medial longitudinal fasciculus (RIMLF) contains [neurons](/entities/neurons) that control vertical saccades and eye movements, affected in progressive supranuclear palsy (PSP)[@bttnerennever2008].
Anatomy
Location
The RIMLF lies in the midbrain, dorsal to the red nucleus, at the level of the superior colliculus.
Neuron Types
Connectivity
- Input: Superior colliculus, frontal eye fields
- Output: Oculomotor nucleus, abducens nucleus
Function
Eye Movement Control
