A man developed cortical blindness after cerebral infarction in the distribution of both posterior cerebral arteries. When he recovered from this condition, he was found to be colour blind in the left visual field, but not in the right. This unusual situation resulted in apparently contradictory performances on hemifield and free-field tasks of colour discrimination, naming, and recognition. The contradictions may be explained by interhemispheric competition between a hemisphere which could discriminate colours and a hemisphere which was colour blind.
一名男子在双侧大脑后动脉供血区域发生脑梗塞后出现皮质盲。当他从这种情况恢复后，发现其左视野色盲，但右视野正常。这种不寻常的情况导致在半视野和全视野的颜色辨别、命名和识别任务中出现明显矛盾的表现。这些矛盾可能是由于能够辨别颜色的半球与色盲半球之间的半球间竞争所解释。
