Sex difference in MWM performance following reduced daytime illumination. MWM performance in trial 1 (24-hour delay) over the 5 training days was compared between female and male grass rats. The female graphs are replotted with data shown in Figure 1, male graphs are replotted using data published in a previous study (Soler JE,Robison AJ,Nunez AA and Yan L, 2018) with permission. (A) In brLD condition, females and males showed comparable performance in MWM task (main effect of sex: F(1,14)=1.01, p > 0.05; interaction between sex and training days: F(4,56)=1.54, p > 0.05). (B) In dimLD condition, males outperformed females in the MWM. There was a significant interaction between sex and training days (F(4,56)=3.739, p < 0.01). Post-hoc comparison revealed a significant difference on training day 4 and 5 (*, p < 0.05). A significant main effect of training days was present in males (F(4,28)=1.29, p < 0.01), but absent in females (F(4,28)=1.29, p > 0.05).
