Brain activity in retinotopic cortex reflects illusory changes in stimulus position. Is this neural signature a general code for apparent position? Here we show that responses in primary visual cortex (V1) are consistent with perception of the Muller-Lyer illusion; however, we found no such signature for another striking illusion, the curveball effect. This demonstrates that V1 does not encode apparent position per se.
视网膜皮层的脑活动反映了刺激位置的错觉变化。这种神经特征是否是明显位置的通用代码？在这里，我们表明初级视觉皮层 (V1) 的反应与 Muller-Lyer 错觉的感知一致；然而，我们没有发现这种特征对于另一种引人注目的错觉，即曲线球效应。这表明 V1 本身并不编码明显的位置。
