Dorsal lesions of the septum influenced the maternal behaviour of Wistar and Long-Evans females, as well as of their hybrids, in a different way. The phenomenon of infanticide appeared in Wistar females only, whereas mothering was not impaired in others. However, the mouse-killing activity was not enhanced in Wistar females displaying infanticide. On the contrary, they exhibited xenoparental behaviour. If these females had grown up in a species-typical environment, characterized by enriched social stimulation during their critical developmental period, no impairment of maternal behaviour following dorsal septal lesions occurred. The ablation of the whole septum caused a break-down of maternal behaviour with the appearance of infanticide in all females regardless of their stock origin and their individual life history. The specific role of the septum in the control of maternal behaviour is discussed.
中隔背侧损伤对Wistar和Long-Evans雌性大鼠及其杂种后代的母性行为产生了不同影响。杀婴现象仅出现在Wistar雌性大鼠中，而其他大鼠的母性抚育行为未受损害。然而，出现杀婴行为的Wistar雌性大鼠的杀鼠活性并未增强。相反，它们表现出异亲抚育行为。如果这些雌性大鼠在典型的物种环境中成长，即在其关键发育期受到丰富的社会刺激，那么中隔背侧损伤后母性行为不会受到损害。切除整个中隔会导致所有雌性大鼠的母性行为崩溃并出现杀婴现象，无论其种群来源和个体生活史如何。本文讨论了中隔在母性行为控制中的具体作用。
