The predatory behaviour of the cuttlefish comprises several stages: prey-detection, orientation, translation and prey-seizing. In this neuroethological study, lesions to the anterior basal lobe were made by an electrolytic method and the animals were allowed to attack their prey in an unrestricted way so that motor defects, functional recovery and the emergence of new adaptative behavioural strategies could be studied. Lesions to the central region of the anterior basal lobe suppress the orientating behaviour, thus only prey situated in the frontal visual field can be seized. Less extensive lesions in this region are associated with similar defects. Without head orientation, the cuttlefish still rotates with its fins. This rotation, however, is usually underestimated, tentacular ejection thus missing the prey. Dorsal lesions cause an underestimation of tentacular strike often associated with defects in maintaining ocular convergence. These results demonstrate the heterogenous function of the anterior basal lobe and its complex role in the control of predatory behaviour.
猎物检测、定位、移动和捕食。在这项神经行为学研究中，通过电解法对前基叶进行损伤，并让动物以不受限制的方式攻击猎物，以便研究运动缺陷、功能恢复和新的适应性行为策略的出现。前基叶中央区域的损伤会抑制定位行为，因此只能捕捉位于正面视野中的猎物。该区域较小范围的损伤也会导致类似的缺陷。在没有头部定位的情况下，乌贼仍会用鳍旋转。然而，这种旋转通常被低估，触须弹出因而错过猎物。背部损伤会导致触须攻击被低估，且常常伴有维持眼球会聚方面的缺陷。这些结果证明了前基叶功能的异质性及其在捕食行为控制中的复杂作用。
