Cerebellar Basket Cells In Neurodegeneration is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
Cerebellar basket cells are inhibitory interneurons that play crucial roles in motor learning and coordination. Their dysfunction contributes to ataxia and movement disorders in neurodegenerative diseases.
Basket cells are GABAergic interneurons located in the molecular layer of the cerebellum. They form distinctive "basket"-like synapses around the axon initial segment of Purkinje cells, providing powerful inhibition.
- Cell body: Small to medium-sized (10-15 μm)
- Axonal projections: Form baskets around Purkinje cell AIS
- Dendritic tree: Sparse, bitufted morphology
- Axon terminals: Multiple synaptic contacts per Purkinje cell
