Spinal Iba1 expression in the superficial and deep laminae of the dorsal horn after injury or sham procedures is unchanged with gabapentin (injury-GBP, sham-GBP) treatment compared to vehicle (injury-vehicle, sham-vehicle). Iba1 expression at day 7 exhibits the same trend in both dorsal horn regions, with no significant difference between injury-GBP and injury-vehicle in either the superficial or the deeper laminae. There is a significant difference (*p<0.01) between those groups and both sham-GBP and sham-vehicle. The scale bar (100 μm) applies to all panels.
