The human primary visual cortex (V1) encodes the perceived position of static but not moving objects
Man-Ling Ho, D. Samuel Schwarzkopf
Abstract
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.
