Supraoesophageal lobes in 11 specimens of Octopus vulgaris were split sagitally into two symmetrical halves and isolated by a thin inert mica barrier. Each half-brain is known to control the four arms on its side of the animal and to be able to learn opposite touch paradigms mediated by its four arms. Powdered cytochalasin D was applied directly in each animal to the subfrontal lobe of one half-brain, and both half-brains were then trained to opposite touch paradigms. The cytochalasin treated half-brains could not learn either touch paradigm whereas the control half-brains learned readily. In another set of four animals, cytochalasin D was similarly applied but to the vertical lobe of one half-brain. In this case all the half-brains learned the touch paradigm.
将11只普通章鱼的食管上叶沿矢状面切成两个对称的半脑，并用一层薄的惰性云母屏障隔开。已知每个半脑控制动物一侧的四条手臂，并能够学习由其四条手臂介导的相反触觉范式。将细胞松弛素D粉末直接应用于每只动物的一个半脑的额下叶，然后对两个半脑进行相反触觉范式的训练。用细胞松弛素处理的半脑无法学习任何一种触觉范式，而对照半脑则很容易学会。在另一组四只动物中，同样应用细胞松弛素D，但应用于一个半脑的垂直叶。在这种情况下，所有半脑都学会了触觉范式。
