Inverted structural AIS plasticity in OB dopaminergic neurons. A, Example maximum intensity projection images of rat TH⁺ neurons costained for ankyrin-G (AnkG) after 24 h treatment in control (10 mm NaCl) or depolarizing (10 mm KCl) conditions. Lines show axon start; arrowheads show AIS start and end positions. Scale bars, 20 μm. B, AIS plot shows the mean ± SEM AIS start and end positions for each group. Mann–Whitney test, ***p < 0.001. C, Cumulative distributions and mean ± SEM plots (insets) for AIS start position, end position, and length for each group. Mann–Whitney test, ***p < 0.001.
