为了测试出蜜蜂能在何时适应新家地址,研究者们关闭蜜蜂“老家”,并训练它们识别“新家”。有成年和老年蜜蜂的小组得到了几天识别“新家”、忘却“老家”的训练。随后科学家拆除“新家”,让不同年龄的蜜蜂们在三个“家庭住址”里选择,这里面就有它们的“老家”地址。
Old bees began flying toward the former nest site, despite the experience that should have told them that it was unusable. "Although many old bees fail in learning tasks, we also discovered that a few still perform with excellence," explains Daniel Minch, lead author of the study and a senior life sciences researcher in Norway.
“老年”蜜蜂开始飞往“老家”地址,尽管它们之前接受了识别“新家”的训练。不过该研究带头人、挪威生命科学高级研究员丹尼尔说道:“尽管许多年纪大的蜜蜂学习失败,我们还是发现其中一些表现极佳。
The scientists believe that their findings with bees offer a new means to model and understand the variability found in brain function between individuals; where some individuals' memories remain intact, while others' learning behavior becomes inflexible with age.
科学家们认为这些研究结果提供了为个体间大脑机制易变性建模及相关理解的新方法,而大脑机制易变性是指,一些个体记忆力保存完好,而另外一些个体的学习行为会随年龄变得迟滞。
