在过去的10年里，我们对视觉处理的总体理解，特别是轮廓整合，发生了巨大的变化。现在有所有积累的心理物理和神经生理学的证据表明，输出的细胞与联合方向偏好和空间位置是整合在过程中的解释的基本轮廓。最近的神经解剖学和神经生理学结果表明，这一过程发生在皮层水平V1。轮廓整合的代码可能是一个时间的代码，因为它可能只在尖峰序列的后半部分作为反馈和横向相互作用的结果而显现出来。在这里，我们回顾了一些属性的轮廓整合从心理物理的角度来看，我们推测石油其潜在的神经生理学基础。(C)2003 Elsevier Ltd.保留所有权利。
Our understanding of visual processing in general, and contour integration in particular, has undergone great change over the last 10 years. There is now all accumulation of psychophysical and neurophysiological evidence that the outputs of Cells With conjoint orientation preference and spatial position are integrated in the process of explication Of rudimentary contours. Recent neuroanatomical and neurophysiological results Suggest that this process takes place at the cortical level V1. The code for contour integration may be a temporal one in that it may only manifest itself in the latter part of the spike train as a result of feedback and lateral interactions. Here we review some of the properties Of contour integration from a psychophysical perspective and we speculate oil their underlying neurophysiological substrate. (C) 2003 Elsevier Ltd.
