When we attempt to fix our gaze, our eyes nevertheless produce so-called 'fixational eye movements', which include microsaccades, drift and tremor. Fixational eye movements thwart neural adaptation to unchanging stimuli and thus prevent and reverse perceptual fading during fixation. Over the past 10 years, microsaccade research has become one of the most active fields in visual, oculomotor and even cognitive neuroscience. The similarities and differences between microsaccades and saccades have been a most intriguing area of study, and the results of this research are leading us towards a unified theory of saccadic and microsaccadic function.
当我们试图凝视时，我们的眼睛仍然会产生所谓的“固视眼动”，包括微扫视、漂移和震颤。固视眼动阻碍了神经对不变刺激的适应，从而防止和逆转固视期间的知觉衰退。在过去的 10 年中，微扫视研究已成为视觉、眼动，甚至认知神经科学中最活跃的领域之一。微扫视和扫视之间的相似性和差异性一直是一个非常有趣的研究领域，这一研究结果使我们朝着扫视和微扫视功能的统一理论迈进。
