Cerebellar Golgi cells (also known as Golgi type II neurons) are inhibitory interneurons located in the granular layer of the cerebellar cortex. First described by Camillo Golgi in 1874, these neurons play critical roles in processing sensory information, regulating motor coordination, and contributing to motor learning. Golgi cells form intricate inhibitory networks within the cerebellar microcircuit, providing feedback inhibition to granule cells and shaping the flow of information through cerebellar pathways [1]. This comprehensive guide covers their anatomical organization, physiological functions, and involvement in neurodegenerative diseases. [1]

The cerebellar cortex has a highly organized laminar structure:
Golgi cells are located throughout the granular layer, with their cell bodies scattered among granule cells and cerebellar glomeruli.
Golgi cells have distinctive morphology:
The glomerulus is a synaptic complex in the granular layer:
Golgi cells exhibit characteristic firing properties:
Golgi cells participate in complex microcircuits:
| Source | Neurotransmitter | Function |
|---|---|---|
| Mossy fibers | Glutamate | Excitatory input |
| Granule cells (via parallel fibers) | Glutamate | Feedback excitation |
| Purkinje cell axons | GABA | Feedforward inhibition |
| Other Golgi cells | GABA | Lateral inhibition |
| Climbing fibers (indirect) | Glutamate | Modulation |
| Target | Neurotransmitter | Effect |
|---|---|---|
| Granule cell dendrites | GABA | Strong inhibition |
| Other Golgi cells | GABA | Network regulation |
| Mossy fiber rosettes | GABA | Presynaptic inhibition |
