Psychophysiological research on the adaptation to optical distortion.

棱镜镜导致的视网膜图像的反转或位移导致视觉引导行为的极端破坏，但经过一段时间的视觉转化后，正常行为逐渐恢复。目前尚不清楚这种适应是否涉及视觉感知的变化，新的运动反应的学习，感觉运动控制系统的修改或身体部位感知位置的本体感受变化。我描述了视野逆转对猴子视觉皮层神经元活动的影响。戴倒转眼镜几个月后，初级视觉皮层的一些细胞开始对不仅在对侧视野而且在同侧视野出现的刺激作出反应。这些细胞对运动的方向和方向没有选择性，但对闪光反应良好。这一结果表明，至少在一定程度上，对视野逆转的适应是由视觉加工通路早期阶段的大规模功能重组介导的。

The reversal or displacement of the retinal image by prism spectaclesleads to extreme disruption of visually guided behavior, but after an extended period of visual transformation normal behavior is gradually restored. It is unclear whether this adaptation involves a change in visual perception, the learning of new motor responses, a modification of the sensorimotor control system or a proprioceptive change in the perceived positions of the body parts. I described the effect of visual field reversal on neuronal activity in the monkey visual cortex. After a few months of wearing reversing spectacles, some cells in the primary visual cortex began to respond to stimuli presented not only in the contralateral visual field but also in the ipsilateral field. These cells were not selective for orientation or direction of motion, but reponded well to a light flash. This result suggests that adaptation to visual field reversal is mediated, at least in part, by a large-scale functional reorganization at an early stage in the visual processing pathway.
