Microglia in the TRN following stab wounds in thalamus. a, b: Representative images of immunoreactivity for CD11b microglia in the TRN (between dashed lines) immediately rostral to the lesion 4 weeks after injury. There is little difference between the injured and contralateral sides. c, d: Confocal images showing signs of activation of β thymosin-+ microglia within the TRN within 500 μm of the lesion, 5 days following injury. The processes of microglia are thicker and less extensively branched than on the contralateral (uninjured) side. The scale bar in (a) also applies to (b) and that in (c) also applies to (d).
