When shown prawns in a glass tube, cuttlefish quickly learn to inhibit their predatory behavior. By using a visual learning paradigm, we studied training and retention performances of cuttlefish aged from 8 to 90 days. We found an improvement in the acquisition of learning abilities during the first 2 months of life as well as an increase of 24-hr retention performance between 30 and 90 days of age. Using morphometric measurements of different lobes of the central nervous system, we correlated the emergence of these learning abilities with the postembryonic development of related nervous structures. Our results show that only the growth of the superior frontal and vertical lobes appears to be significantly correlated with the improvement of learning and long-term retention performances. Thus, as found in earlier data collected in Octopus, the vertical lobe complex of the cuttlefish seems to be involved in these learning processes.
当向乌贼展示玻璃管中的对虾时，它们会很快学会抑制捕食行为。通过使用视觉学习范式，我们研究了8至90天大的乌贼的训练和记忆表现。我们发现，在生命的前两个月，学习能力的获得有所改善，并且在30至90日龄之间，24小时记忆表现有所提高。通过对中枢神经系统不同叶的形态测量，我们将这些学习能力的出现与相关神经结构的胚胎后发育联系起来。我们的结果表明，只有额叶上部和垂直叶的生长似乎与学习和长期记忆表现的改善显著相关。因此，正如在章鱼早期收集的数据中所发现的那样，乌贼的垂直叶复合体似乎参与了这些学习过程。
