Abstract
After complete removal of the optic tectum, nurse sharks can learn to discriminate black versus white and horizontal versus vertical stripes. This finding is contrary to the traditional belief of exclusive tectal control over visuomotor behavior in lower vertebrates and suggests a role for the telencephalon in the vision of these primitive animals.
摘要
在完全切除视顶盖后，护士鲨能够学会区分黑色与白色以及水平条纹与垂直条纹。这一发现与传统观点相悖，传统观点认为在低等脊椎动物中视顶盖对视觉运动行为具有排他性控制，这表明端脑在这些原始动物的视觉中发挥了作用。
