Spinal but not cortical microgliosis after peripheral nerve injury. Left column, sham-operated; right column, peripheral nerve injury. Nerve injury evoked an ipsilateral increase of microglial cells in L4 spinal dorsal horns. Asterisks indicate contralateral side of nerve injury. The structures in the cortex are indicated by arrow or enclosed by dashed lines. 1, ACC (Anterior cingulate cortex). Bar = 350 μm. Modified from [66].
