Accessory Olive (Ao) Neurons is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes. [1]
The Accessory Olive (AO), comprising the medial and dorsal accessory olives, is a crucial cerebellar input nucleus involved in motor learning and timing. [2]
