Abstract

Perceptual disappearance of a salient target induced by a moving texture mask (MIB: Motion-Induced Blindness) is a striking effect, currently poorly understood. Here, we investigated whether the dynamics of MIB qualify as an excitable system. Excitable systems exhibit fast switches from one state to another (e.g., visible/invisible) induced by an above-threshold perturbation and stimulus-independent dynamics, followed by a refractory period. In the experiments, disappearance was induced by masks consisting of slowly rotating radial bars with a gap at the target location, leading to periodic perturbation of the visual field around the target (a bright parafoveal spot). When passed around the target location, masks frequently induced an abrupt target disappearance, pointing to locality. As expected from excitable systems, the disappearance time was not affected by additional bars crossing the target during invisibility, and there was little dependence on the mask configuration. After the target reappeared, it stayed for at least 0.5–2 s (the refractory period). Therefore, the dynamics governing MIB represent an example of an excitable system, where the transition to the invisible state is induced by the mask. The dynamics that follow were determined mostly by the internal network properties.

运动性失明是一种噪声兴奋系统。
运动纹理掩膜(MIB:Motion-Induced Blindness,运动诱导性失明)引起的突出目标知觉消失是一种惊人的效应,但目前人们对这种效应还知之甚少。在这里,我们研究了 MIB 的动态是否符合兴奋系统的条件。可兴奋系统会在高于阈值的扰动和与刺激无关的动态诱导下,表现出从一种状态到另一种状态(如可见/不可见)的快速切换,随后是一个折射期。在实验中,消失是由在目标位置有间隙的缓缓旋转的径向条组成的遮罩诱发的,从而导致目标周围视野的周期性扰动(一个明亮的视网膜旁光点)。当通过目标位置周围时,遮罩经常会导致目标突然消失,这表明了定位性。正如可兴奋系统所预期的那样,消失时间不受隐形期间穿过目标的附加条纹的影响,而且与遮罩配置的关系不大。目标再次出现后,至少会停留 0.5-2 秒(折射期)。因此,支配 MIB 的动力学代表了一个可兴奋系统的例子,其中向隐形状态的过渡是由面具诱发的。随后的动力学主要由内部网络特性决定。

期刊介绍: Vision Research is a journal devoted to the functional aspects of human, vertebrate and invertebrate vision and publishes experimental and observational studies, reviews, and theoretical and computational analyses. Vision Research also publishes clinical studies relevant to normal visual function and basic research relevant to visual dysfunction or its clinical investigation. Functional aspects of vision is interpreted broadly, ranging from molecular and cellular function to perception and behavior. Detailed descriptions are encouraged but enough introductory background should be included for non-specialists. Theoretical and computational papers should give a sense of order to the facts or point to new verifiable observations. Papers dealing with questions in the history of vision science should stress the development of ideas in the field.
