Bergmann glia, a type of glia also known as radial epithelial cells (as named by Camillo Golgi) or Golgi epithelial cells (GCEs; not to be mixed up with Golgi cells), are astrocytes in the cerebellum that have their cell bodies in the Purkinje cell layer and processes that extend into the molecular layer, terminating with bulbous endfeet at the pial surface. Bergmann glia express high densities of glutamate transporters that limit diffusion of the neurotransmitter glutamate during its release from synaptic terminals. Besides their role in early development of the cerebellum, Bergmann glia are also required for the pruning or addition of synapses.
