A simple model is shown to account for a large range of V1 classical, and nonclassical, receptive field properties including orientation tuning, spatial and temporal frequency tuning, cross-orientation suppression, surround suppression, and facilitation and inhibition by flankers and textured surrounds. The model is an implementation of the predictive coding theory of cortical function and thus provides a single computational explanation for a diverse range of neurophysiological findings. Furthermore, since predictive coding can be related to the biased competition theory and is a specific example of more general theories of hierarchical perceptual inference, the current results relate V1 response properties to a wider, more unified, framework for understanding cortical function.
一个简单的模型解释了大范围的 V1 经典和非经典感受野特性，包括方向调谐、空间和时间频率调谐、交叉方向抑制、周围抑制，以及侧翼和纹理周围的促进和抑制。该模型是皮层功能预测编码理论的实现，因此为大量神经生理学发现提供了单一的计算解释。此外，由于预测编码可以与有偏差的竞争理论相关，并且是分层感知推理的更一般理论的具体例子，因此当前的结果将 V1 反应特性与更广泛、更统一的皮层功能理解框架联系起来。
