Cerebellar Granule Cells (Expanded) 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 Granule Cells are the most abundant neuron type in the mammalian brain, constituting approximately 50% of all neurons in the cerebellum. These small, densely packed excitatory neurons form the primary input layer of the cerebellar cortex and play essential roles in motor learning, coordination, and cognitive functions. [1]
