Fig. 2.1.34. A reconstructed dendritic branchlet of a cerebellar Purkinje  cell. Its numerous spines are completely ensheathed (except  synapsing axon terminals) by processes of Bergmann astrocytes  (blue). A volume of glial processes is two times higher in the cerebellar  cortex (mouse) than in hippocampus (rat). Edge of scale cube = 0.2 µm. (Cf. Fig. 2.1.32. B.)
