线或光栅的感知方向受到周围图像的方向结构的影响：倾斜错觉。在这里，我提供了一个选择性的文献回顾倾斜错觉，侧重于功能方面。该评论探讨了基于感觉增益控制的倾斜错觉的机械帐户的优点，其中神经元的反应是正常化的汇集活动的其他单位。方向选择性神经元之间的抑制的作用进行了讨论，有人认为，它们相关的去抑制也必须考虑到，以模拟全角度依赖的倾斜错觉环绕方向。平行线绘制与适应调制的时间，而不是空间的背景下，图像片段的处理。倾斜错觉的色彩选择性及其对周围环境可见度的依赖程度被用来推断神经元归一化池的特性和增益控制操作的皮层处理层次结构中的位点。最后，最近的证据进行了讨论，作为精神分裂症的生物标志物的倾斜错觉可能的临床相关性。(C)2014爱思唯尔有限公司版权所有。
The perceived orientation of a line or grating is affected by the orientation structure of the surrounding image: the tilt illusion. Here, I offer a selective review of the literature on the tilt illusion, focusing on functional aspects. The review explores the merits of mechanistic accounts of the tilt illusion based upon sensory gain control in which neuronal responses are normalized by the pooled activity of other units. The role of inhibition between orientation-selective neurons is discussed, and it is argued that their associated disinhibition must also be taken into account in order to model the full angular dependence of the tilt illusion on surround orientation. Parallels are drawn with adaptation as modulation by the temporal rather than spatial context within which an image fragment is processed. The chromatic selectivity of the tilt illusion and the extent of its dependence on the visibility of the surround are used to infer characteristics of the neuronal normalization pools and the loci in the cortical processing hierarchy at which gain control operates. Finally, recent evidence is discussed as to the possible clinical relevance of the tilt illusion as a biomarker for schizophrenia. (C) 2014 Elsevier Ltd. All rights reserved.
