Correlations between the percentage of time postpartum female laboratory rats spent in the open arms of an elevated plus maze and the time they had spent in the light chamber of the light–dark box before mating. (A) All subjects, (B) subjects with no offspring contact for 4 h before elevated plus-maze testing, (C) subjects with offspring contact until elevated plus-maze testing. Data were log-transformed before analysis. Circles – offspring were present before testing; triangles – offspring were not present before testing.
