我们调查了是否本体感受的眼睛位置信号执行后的扫视眼球运动是用来估计运动的准确性。如果是这样的话，扫视适应，保持扫视准确性的机制，可以以类似的方式使用这个信号，因为它在扫视后使用视觉反馈。为了操纵本体感受眼睛位置信号的可用性，我们利用了这样的发现，即本体感受眼睛位置信息在与典型的扫视潜伏期相当的时间间隔内在扫视之后逐渐建立。我们通过要求参与者快速返回扫视到固定点来限制凝视在扫视着陆点的保留时间，该固定点抢占了本体感受眼睛位置信号的可用性。在五个实验条件下，我们测量的视觉和本体感觉反馈的影响，一起和单独，适应的发展。我们发现，适应以前缩短的扫视的情况下，视觉反馈不可用的扫视后显着较弱时，使用本体感受的眼睛位置信息受损的快速返回扫视。我们的结论是，适应可以驱动本体感受的眼睛位置feedback.NEW & NOTEWORTHYWe表明，本体感受的眼睛位置信息后，扫视估计电机错误和适应扫视控制。以往的眼跳适应研究主要集中在对眼跳准确性的视觉反馈上。结合视觉和本体感受信息的多模态误差信号可能更鲁棒。此外，结合本体感觉和视觉测量的扫视性能可以有助于保持视觉，本体感觉，和电机控制对齐，并产生一个连贯的空间表示。
We investigated whether the proprioceptive eye position signal after the execution of a saccadic eye movement is used to estimate the accuracy of the movement. If so, saccadic adaptation, the mechanism that maintains saccade accuracy, could use this signal in a similar way as it uses visual feedback after the saccade. To manipulate the availability of the proprioceptive eye position signal we utilized the finding that proprioceptive eye position information builds up gradually after a saccade over a time interval comparable to typical saccade latencies. We confined the retention time of gaze at the saccade landing point by asking participants to make fast return saccades to the fixation point that preempt the usability of proprioceptive eye position signals. In five experimental conditions we measured the influence of the visual and proprioceptive feedback, together and separately, on the development of adaptation. We found that the adaptation of the previously shortened saccades in the case of visual feedback being unavailable after the saccade was significantly weaker when the use of proprioceptive eye position information was impaired by fast return saccades. We conclude that adaptation can be driven by proprioceptive eye position feedback.NEW & NOTEWORTHYWe show that proprioceptive eye position information is used after a saccade to estimate motor error and adapt saccade control. Previous studies on saccadic adaptation focused on visual feedback about saccade accuracy. A multimodal error signal combining visual and proprioceptive information is likely more robust. Moreover, combining proprioceptive and visual measures of saccade performance can be helpful to keep vision, proprioception, and motor control in alignment and produce a coherent representation of space.
