Female Sprague Dawley Rats Show Impaired Spatial Memory in the 8-Arm Radial Maze under Dim Blue and Red Light

Table 2

Cross-table of marked versus unmarked arms. The cross-table shows the total (baited and unmarked; unbaited and marked) and the averaged (baited and marked; unbaited and unmarked) visits of four categories of arms at session 5 of all light exposure groups. Baited arms (1, 4, 5, and 7), unbaited arms (2, 3, 6, and 8), marked arms (with visual cues; 1, 3, 5, and 7) and unmarked arms (without visual cues; 2, 4, 6, and 8) (see also Figure 1(a)). Results of the Poisson regression analysis are shown in the cross-table for the effect of baited versus unbaited arms and for the effect of marked versus unmarked arms. (*** ; ns: not significant).
