(A, B) Shows examples of the ramified microglia. Hypertrophic microglia are shown in (C, D). In (C), microglia can be seen surrounding the soma of a pyramidal neuron. (E) shows dystrophic microglia with swellings, beaded, and discontinuous processes. (F) shows an example of dystrophic microglia that are small and de-ramified, with beaded processes. The scale bar is 50 μm.
