Visual perception during movements of the eyes and head

视觉感知是意识体验的一个组成部分，因此人类大脑的近一半用于处理视觉图像也就不足为奇了。对于准确的视觉感知来说，同样重要的是移动眼睛、头部和身体的能力。这样的运动使我们能够彻底地探索我们的周围环境，但它们也会在传入的视觉图像中引入突然的变化。然而，我们对视觉世界的感知是相当稳定的，这表明大脑的视觉处理中心包含补偿这种干扰的机制。了解大脑如何完成这一壮举是神经科学中最重要的问题之一，因为它关系到大脑如何使用来自自身运动命令的反馈来实现准确和稳定的感觉处理的更普遍的问题。事实上，反馈电机控制的问题是在许多领域，从机器人到人机界面的设计普遍感兴趣。

Visual perception is an integral part of conscious experience, and so it is not surprising that nearly half the human brain is devoted to the processing of visual images. Equally important for accurate visual perception is the ability to move the eyes, head, and body. Such movements allow us to explore our surroundings thoroughly, but they also introduce abrupt changes in the incoming visual images. Nevertheless, our perception of the visual world is quite stable, indicating that the visual processing centres of the brain contain mechanisms that compensate for such disturbances. Understanding how the brain accomplishes this feat is one of the most important questions in neuroscience, as it bears on the more general question of how the brain uses feedback from its own motor commands to achieve accurate and stable sensory processing. Indeed the issue of feedback motor control is of general interest in a number of domains, ranging from robotics to the design of human-machine interfaces.
