Additional file 6 of Effects of test experience, closed-arm wall color, and illumination level on behavior and plasma corticosterone response in an elevated plus maze in male C57BL/6J mice: a challenge against conventional interpretation of the test

Additional File 6: Table 1. Illumination levels in the elevated plus maze of closed arms with different color walls and under different light conditions. For the second group of mice, the illumination level was set to 100 lx at the center of the maze with closed arms with transparent blue walls. Measurements of illumination levels at each location of the maze (central platform, end of the open arms, and end of the closed arms) were repeated three times, and the average was calculated. For the third group of mice, the illumination level was set to 5, 100, or 800 lx at the center of the maze with closed arms with transparent blue walls. *The measurement sensor of the illuminometer was placed on the floor of the central platform and the end of the floor of the open arm horizontally. To measure the illumination level in the closed arm, the sensor was tilted due to the size of the illuminometer.
