PNN expression in the motor cortex L5 post stroke. Representative immunolabeling of WFA (green) and (A) PV (red) or (C) Kv3.1 (red) shows PNN expression around motor cortical L5 interneurons. B, D Percentage of PV (B) and Kv3.1 (D) expressing neurons coated with PNNs. Graphs are bar plots showing mean ± SD and data as dots. Asterisks and hashes denote significant differences with the control and stroke groups, correspondingly, as indicated by two-way ANOVA and t-tests (^#p < 0.05, **p < 0.01, ***p < 0.001), n = 7. Scale bars, 100 µm. DPI, days post ischemia; PV, parvalbumin
