In two groups of newly hatched cuttlefish, from eggs incubated at different temperatures, the emergence of predatory pursuit was correlated with the development of some characteristics of the vertical lobe complex (namely, the development of the vertical and superior frontal lobes and the appearance of the vertical-subvertical lobe tracts) and with the state of resorption of the inner yolk sac. The temperature of egg incubation influences the appearance of postnatal pursuit behavior. Expression of this predatory behavioral characteristic is concomitant with the appearance of the vertical-subvertical lobe tracts. In contrast, the growth of the vertical and the superior frontal lobes relative to the growth of the supraesophageal mass and final yolk absorption are not correlated with the appearance of pursuit. To maintain a prey in the frontal visual field during predatory pursuit, short-term memory processes must be involved. Thus, the development of the vertical-subvertical lobe tracts, which is concomitant with the emergence of pursuit, appears essential in the maturation of these short-term memory processes.
在两组新孵化的乌贼中，它们来自在不同温度下孵化的卵，捕食性追逐行为的出现与垂直叶复合体某些特征的发育（即垂直叶和上额叶的发育以及垂直 - 亚垂直叶束的出现）以及内卵黄囊的吸收状态相关。卵孵化的温度会影响出生后追逐行为的出现。这种捕食性行为特征的表达与垂直 - 亚垂直叶束的出现同时发生。相比之下，垂直叶和上额叶相对于食管上神经节团块的生长以及最终卵黄吸收与追逐行为的出现并无关联。在捕食性追逐过程中，为了将猎物维持在正面视野中，必须涉及短期记忆过程。因此，与追逐行为出现同时发生的垂直 - 亚垂直叶束的发育，在这些短期记忆过程的成熟中似乎至关重要。
