Term: unipolar brush neuron

Definition: These neurons have rounded or ovoidal cell bodies (9-12 micrometers in diameter) that are intermediate in size between granule and Golgi cells. Within a given folium, the UBCs occur at all levels of the granular layer (Fig 1.c), sometimes immediately beneath the Purkinje cell layer and also in the folial withe matter (Fig. 1c, f).
