Female Sprague Dawley Rats Show Impaired Spatial Memory in the 8-Arm Radial Maze under Dim Blue and Red Light
Figure 1
(a) Baiting pattern (black dots) and location of visual cues in the 8-arm radial maze. (b) Spectral irradiance distribution plotted against the wavelength [nm] of the used light sources (white, blue, and red). (c) Error definition (RME: reference memory errors; WME: working memory errors; RWME: reference/working memory errors). (d) Brightness of light in the center of the maze and in the proximal and distal arms of the maze given as mean SEM lux (). (e) Study design (S1–S5: session 1–5; shaded boxes: days without trials).
