对普通章鱼视觉系统的反应进行了研究。在自由游泳的动物对短暂闪光的反应中进行粗略记录。在眼内记录简单的负视网膜电图[ERT]，开始于8毫秒，峰值在20-25毫秒。在动物休息时，轻微的触觉刺激可以增加ERG的幅度，而触觉刺激不产生运动或瞳孔变化。紧接视网膜后面，在闪光后15毫秒开始并以每秒约150次的频率持续约40毫秒记录后振荡电位。这被认为是由视觉神经纤维中以每秒约1米的速度行进的同步齐射产生的。在视叶中，可以记录ERG、到达的振荡齐射和在闪光后30毫秒开始并在20毫秒后达到峰值的总反应。
A study of responses in Octopus vulgaris visual system was carried out. Gross recordings were made in the free swimming animal responding to brief flashes of light. A simple negative electroretinogram [ERT] was recorded within the eye beginning at 8 msec peaking at 20-25 msec. With the animal resting, the amplitude of the ERG could be increased by gentle tactile stimuli which produce no movement or pupil change. Immediately behind the retina, aft oscillating potential was recorded beginning 15 msec after the flash and lasting for about 40 msec with a frequency of about 150 per second. This was believed to be produced by synchronized volleys in the optic nerve fibers travelling at about 1 m per sec. In the optic lobe, one could record the ERG, the arriving oscillatory volley and a gross response starting at 30 msec after the flash and peaking 20 msec later.
