7-OH-DPAT treatment partially restores TH immunolabeling in the ipsilateral SN_C. A–C, Photomicrographs depicting TH immunolabeling in the ipsilateral SN_C after 2, 4, and 8 weeks of 7-OH-DPAT treatment. D, TH⁺ cell counts in the ipsilateral SN_C. Each bar represents the mean percentage (±SEM, n = 6) of TH⁺ cells remaining in the ipsilateral SN_C relative to the contralateral, intact hemisphere based on total cell counts. Significant difference from saline-treated controls, ∗∗p < 0.001; ∗p < 0.02.
