Performances of lactating rats with normal or small litters and non-lactating rats on elevated plus-maze (a % time into the open arms; b % entries into the open arms, and c number of entries into the arms) and open field apparatus (d number of entries into the center and periphery, total entries, and ratio center/total entries). Data are presented as the mean ± SEM. *p < 0.05; **p < 0.01; ***p < 0.001, compared to non-lactating rats. ^#p < 0.05, p < 0.01 compared to lactating (normal litter) rats
