Rotor rod behavioral measurements: control (black), naïve (red), 3.12 μg/μL (green), 6.25 μg/μL (gray), and 12.5 μg/μL (blue). Rotor rod forced motor movement percentage change from baseline; groups were trained and combined for baseline measurements. Groups were separated after stroke surgery into control, naïve, and GTN treated and were tested on PSD 1, 3, and 7 (n=6 per group). */#p<0.05. GTN, glyceryl trinitrate; PSD, post-stroke day.
