Unipolar brush cells (UBCs) are a class of excitatory glutamatergic interneuron found in the granular layer of the cerebellar cortex and also in the granule cell domain of the cochlear nucleus. == Structure == The UBC has a round or oval cell body with usually a single short dendrite that ends in a brush-like tuft of short dendrioles (dendrites unique to UBCs). These brush dendrioles form very large synaptic junctions. The dendritic brush and the large endings of the axonal branches are involved in the formation of cerebellar glomeruli. The UBC has one short dendrite where the granule cell has four or five. The brush dendrioles emit numerous, thin evaginations called filopodia, unique to UBCs. The filopodia emanate from all over the neuron, even including the dendritic stem and the cell body in some cells. Although UBC filopodia do not bear synaptic junctions, they are nevertheless involved in cell signaling.〔Jaarsma D, Diño MR, Ohishi H, Shigemoto R, Mugnaini E.
