我们研究了双目失明猫（BD猫）和对照组猫（C猫）的全局运动检测。这些猫被训练在两种自由选择的跑步装置中，以获得食物奖励。正刺激是一个移动的随机点模式，所有的点都在一个方向上移动，负刺激是相同的随机点模式，但静止。与C组相比，BD组猫对整体运动刺激的检测能力严重受损。相比之下，它们在简单的相对运动检测任务（一个正方形）中的表现水平与C猫没有差异，然而，在更复杂的相对运动检测任务（两个正方形）中，BD猫的表现受到损害。BD猫的全局运动检测缺陷可能是由于它们的y通路受损。(C) 2002 Elsevier Science B.V.版权所有
We investigated global motion detection in binocularly deprived cats (BD cats) and control cats (C cats). The cats were trained in the two-choice free running apparatus for a food reward. The positive stimulus was a moving random-dot pattern with all dots moving in one direction, the negative stimulus was the same random-dot pattern but stationary. The BD cats were severely impaired in detection of global motion stimulus as compared with the C cats. In contrast, their level of performance in a simple relative motion detection task (one square) did not differ from that in the C cats, However, in more complex relative motion detection task (two squares) the performance of the BD cats was impaired. The deficit in the detection of global motion in BD cats may be due to impairments of their Y-pathway. (C) 2002 Elsevier Science B.V. All rights reserved.
