Abstract

Previous studies in rabbits have shown that a unilateral ablation of the occipital lobe leads to a severe impairment of the ability to discriminate striated patterns. Considerable retraining is required in order to reach the 90% correct level with the eye contralateral to the lesion. In the present study the effects of a unilateral and bilateral ablation are compared. It is concluded that the rudimentary ability to discriminate patterns with the eye contralateral to a unilateral ablation of the occipital lobe is mediated by the remaining ipsilateral cortical projection and not by subcortical structures.

摘要

之前在兔子身上进行的研究表明，单侧枕叶切除会导致辨别条纹图案的能力严重受损。为了使损伤对侧眼睛达到90%的正确辨别水平，需要进行大量的再训练。在本研究中，比较了单侧和双侧切除的效果。得出的结论是，单侧枕叶切除后，损伤对侧眼睛辨别图案的基本能力是由剩余的同侧皮质投射介导的，而不是由皮质下结构介导的。
