Behavioral performance on the EPM across trials under distinct lighting conditions.

Basic movements (A), and open arm distance (B), time (C) and entries (D) across two trials conducted under different lighting conditions. Data are presented as the mean and standard error (Dim First: N = 6; Lit First: N = 7). A significant difference between lighting conditions is denoted by double asterisks (**) and a significant effect of trial order is denoted by a single asterisk (*).
