::::
The Fastigial Nucleus (also known as the Fastigial Cerebellar Nucleus or Nucleus Fastigii) is the most medial of the three cerebellar deep nuclei. It receives inhibitory GABAergic input from Purkinje cells of the cerebellar vermis and serves as the primary output channel for the vestibulocerebellum. The fastigial nucleus plays critical roles in posture, balance, axial muscle tone, and vestibulo-ocular reflex modulation.
Morphology
The Fastigial Nucleus receives input from:
The fastigial nucleus shows significant neurodegeneration in MSA, particularly in the cerebellar variant (MSA-C). This contributes to:
Fastigial involvement in PSP contributes to:
Key differentially expressed genes from Allen Brain Atlas:
The study of Fastigial Nucleus (Fastigial Cerebellar Nucleus) Neurons has evolved significantly over the past decades. Research in this area has revealed important insights into the underlying mechanisms of neurodegeneration and continues to drive therapeutic development.
Historical context and key discoveries in this field have shaped our current understanding and will continue to guide future research directions.
