Previous research suggests binocular rivalry disrupts extrastriate, but not striate processes, although the locus along the visual pathway at which such disruption first occurs is uncertain. It has been argued that subjective contours arise via a two-stage process in which end-stopped cells feed into orientation-sensitive neurones in V2, and that orientation aftereffects induced with subjective contours are the product of mechanisms similar to those giving rise to real contour aftereffects. If binocular rivalry disrupts the acquisition of subjective contour aftereffects, then it follows from this model that rivalry disrupts processing in V2. Experiments reported here confirm this and provide evidence which suggests binocular rivalry arises through interactions between binocular neurones, rather than via some type of specialized binocular rivalry mechanism.
先前的研究表明，双眼竞争会干扰纹外区域，但不会干扰纹状区域的过程，尽管这种干扰首次发生在视觉通路中的具体位置尚不确定。有人认为，主观轮廓是通过一个两阶段过程产生的，在这个过程中，终端停止细胞输入到V2区的方向敏感神经元中，并且由主观轮廓诱发的方向后效是与产生真实轮廓后效的机制类似的机制的产物。如果双眼竞争会干扰主观轮廓后效的获得，那么根据这个模型可以推断，竞争会干扰V2区的加工过程。此处报告的实验证实了这一点，并提供了证据表明双眼竞争是通过双眼神经元之间的相互作用产生的，而不是通过某种类型的专门的双眼竞争机制。
