Fluorescence responses in each section of fast muscles during escape, turn, and swimming movements. A1-A3 Each panel represents data for a specific movement type: Escape A1, Turn A2, and Swimming A3. Y-axis scaling is adjusted for each movement type to emphasize fluorescence response differences. Data from the same trial are color coded. B1-B3 Each panel shows data for a specific section of fast muscles, allowing comparison across muscle regions: B1 Lateral, B2 Intermediate, and B3 Medial. Here, the Y-axis scaling is consistent across the panels, allowing direct comparison between muscle sections. Thick lines indicate the mean response, and thin lines represent ± SD (standard deviation)
