Cerebellar Functional Anatomy: a Didactic Summary Based on Human fMRI Evidence

Area of Science:

• Neuroscience
• Neuroimaging
• Cerebellar Function

Background:

• The cerebellum plays a crucial role in both motor and non-motor behaviors.
• Neuroimaging studies frequently reveal cerebellar involvement in brain function and dysfunction.
• Existing literature maps motor and non-motor functions in the healthy human cerebellar cortex using functional magnetic resonance imaging (fMRI).

Discussion:

• Cerebellar findings in neuroimaging, such as atrophy in Alzheimer's disease, can be understood by referencing functional maps of specific cerebellar regions.
• This framework aids in interpreting task-based, resting-state, and gradient-based fMRI studies.
• Understanding normal cerebellar organization is key to interpreting functional neuroimaging data.

Key Insights:

• Consistent organizational principles have been identified across numerous studies of normal cerebellar function.
• Specific cerebellar regions, like Crus I/II and lobule IX, have well-documented functional characteristics.
• This summary provides a foundational understanding of cerebellar functional topography.

Outlook:

• This framework will assist researchers in interpreting functional neuroimaging experiments involving the cerebellum.
• It serves as a valuable resource for understanding cerebellar contributions to behavior in various conditions.
• Further research can build upon this organizational map to explore complex cerebellar roles.
