Fastigial Nucleus

The most medial of the deep cerebellar nuclei, primarily involved in controlling balance, posture, and eye movements, and receives input from the vermis.

Key Functions:

• Controls axial and proximal limb muscles for balance and posture.
• Involved in eye movements and vestibulo-ocular reflex.
• Receives input from the vermis and projects to the vestibular nuclei and reticular formation.

Interacting Systems & Components:

• Cerebellum (deep cerebellar nucleus)
• Vermis (receives input from)
• Vestibular System (interacts with for balance)
• Reticular Formation (projects to)
• Balance and Posture (essential for)
