This study aims to analyze the effects of electrolytic lesion, restricted to either the ventral or the dorsal parts of the vertical lobe (VL), on the behavior of cuttlefish (Sepia officinalis). Two behavioral tests were performed on sham-operated and lesioned cuttlefish: assessment of locomotor activity in an open field and determination of spatial learning abilities in a T maze. The results showed that ventral lesions of the VL led to marked impairment in the acquisition of spatial learning, whereas dorsal lesions of the VL increased locomotor activity in the open field and impaired long-term retention of spatial learning. This study establishes for the first time the existence of distinct functions in the ventral and the dorsal parts of the VL in cephalopods.
本研究旨在分析仅限于垂直叶（VL）腹侧或背侧部分的电解损伤对乌贼（Sepia officinalis）行为的影响。对假手术和损伤后的乌贼进行了两项行为测试：在开放场地评估运动活动，以及在T迷宫中测定空间学习能力。结果表明，VL腹侧损伤导致空间学习获取明显受损，而VL背侧损伤增加了开放场地的运动活动，并损害了空间学习的长期记忆。本研究首次证实头足类动物VL腹侧和背侧部分存在不同功能。
