The effect of age on the development of hyperemotionality including muricide induced by either olfactory bulbectomy or isolated housing was studied in rats. In olfactory bulbectomized groups, 13-week-old rats showed the highest score of emotionality and shortest latency in the onset of hyperemotionality and muricide among any other groups of rats. On the other hand, in the groups subjected to isolation, 4-week-old rats showed a higher score of emotionality than 13-week-old rats. These results suggest that the age of the rat at the beginning of experiment is quite important in the induction of hyperemotionality following both olfactory bulbectomy and isolated housing.
研究了年龄对大鼠过度情绪化发展的影响，包括嗅球切除或单独饲养诱导的杀鼠行为。在嗅球切除组中，13周龄的大鼠在所有其他大鼠组中表现出最高的情绪得分，且过度情绪化和杀鼠行为发作的潜伏期最短。另一方面，在单独饲养组中，4周龄的大鼠比13周龄的大鼠表现出更高的情绪得分。这些结果表明，实验开始时大鼠的年龄在嗅球切除和单独饲养后诱导过度情绪化方面非常重要。
