Pars Reticulata (SNr)

The ventral part of the substantia nigra, serving as a major output nucleus of the basal ganglia, involved in regulating eye movements and head orientation.

Key Functions:

• Inhibits activity in the thalamus and superior colliculus.
• Regulates eye movements, particularly saccades.
• Contributes to head and trunk orientation.

Interacting Systems & Components:

• Substantia Nigra (part of)
• Basal Ganglia (output nucleus of)
• Striatum (receives input from)
• Thalamus (projects to)
• Superior Colliculus (projects to)
• Eye Movements (involved in)
