Species differences and the effects of oxytocin (OT) on behaviors in the open field test. Female meadow voles showed a longer latency to enter the center (A), made fewer entries to center squares (B), spent less time in the center (C), and showed a lower level of locomotor activity (D) compared to prairie voles. The OT-treated females showed fewer center entries compared to CSF-injected females (B). OT treatment did not alter other behaviors in the open field. *Indicates significant treatment effects at p < 0.05; while alphabetic letters indicate species differences. Error bars represent standard errors of the mean (SEM).
