Lugaro cell
Lugaro cells are primary sensory
The Lugaro cell has a major role in the cerebellum, interconnecting many neurons located in all layers of the cortex. It samples information from the Purkinje cell axon collaterals and forwards this information to the molecular and granular layers of the cerebellum. The axons of the Lugaro cells only contact inhibitory interneurons such as the
The Lugaro cell axon can sometimes take a curving detour through the granular layer, before running its parallel course in the molecular layer. The axon dips through the granular layer, into the white matter, before going up to terminate on basket or stellate cells in the molecular layer.
Sometimes the Lugaro cell axon will also terminate on Golgi cells in the granular layer without going on up again to the molecular layer, so that the Golgi cells are the target. According to Dieudonne, the Lugaro cell forms a major input to Golgi cells, and one Lugaro cell may contact up to 100 Golgi cells.[2]
