最近的研究表明，扫视向内适应（即，扫视幅度的缩短）和扫视向外适应（即，扫视幅度的延长）依赖于部分不同的神经元机制。越来越多的证据表明，这些差异是基于差异的目标注册或规划阶段，因为向外，而不是向内的适应转移到手指向和感知定位的闪光目标。此外，反应性扫视适应的转移到长时间的重叠和扫描扫视是更强的扫视向外适应后，比扫视向内适应后，这表明在向外适应过程中的调制目标注册阶段越来越多地用于执行扫视时，扫视目标是视觉上可用的时间较长。反应性扫视和扫描扫视之间的目标呈现持续时间的差异也与不同目标的感知定位的差异有关。闪烁的目标是错误定位后向内适应的反应性和扫描扫视，但目标，提出了一个较长的时间（固定目标）的错误定位后，扫描比反应性扫视。知觉定位和适应特异性之间的这种联系表明，静止条的错误定位后向外反应性眼跳后，应高于向内适应。在本研究中，我们验证了这一预测。我们发现，相对量的错误定位的固定与闪烁的酒吧后向外比后向内适应反应性眼跳。此外，在固定固定和闪光杆后，但不是向内适应后，向外定位错误。因此，我们的研究结果进一步证明了内向适应和外向适应之间的不同适应机制，并协调了最近的一些研究。
Recent studies have shown that saccadic inward adaptation (i.e., the shortening of saccade amplitude) and saccadic outward adaptation (i.e., the lengthening of saccade amplitude) rely on partially different neuronal mechanisms. There is increasing evidence that these differences are based on differences at the target registration or planning stages since outward but not inward adaptation transfers to hand-pointing and perceptual localization of flashed targets. Furthermore, the transfer of reactive saccade adaptation to long-duration overlap and scanning saccades is stronger after saccadic outward adaptation than that after saccadic inward adaptation, suggesting that modulated target registration stages during outward adaptation are increasingly used in the execution of saccades when the saccade target is visually available for a longer time. The difference in target presentation duration between reactive and scanning saccades is also linked to a difference in perceptual localization of different targets. Flashed targets are mislocalized after inward adaptation of reactive and scanning saccades but targets that are presented for a longer time (stationary targets) are mislocalized stronger after scanning than after reactive saccades. This link between perceptual localization and adaptation specificity suggests that mislocalization of stationary bars should be higher after outward than that after inward adaptation of reactive saccades. In the present study we test this prediction. We show that the relative amount of mislocalization of stationary versus flashed bars is higher after outward than that after inward adaptation of reactive saccades. Furthermore, during fixation stationary and flashed bars were mislocalized after outward but not after inward adaptation. Thus, our results give further evidence for different adaptation mechanisms between inward and outward adaptation and harmonize some recent research.
