418货车GISBERGEN、罗宾逊和GIELEN神经元可以由运动误差信号驱动，该运动误差信号是通过监测传出信号获得的瞬时眼睛位置与由高级视觉或认知中心指定的眼眶中的期望眼睛位置之间的差。突发神经元放电率绘制对瞬时和最终的眼睛位置之间的差异，在扫视，适当校正的最后共同path.In 89%的水平作用的突发神经元检查，关系遵循一个共同的轨迹扫视的所有大小的开和关的方向。对于这些细胞，爆发放电率可能确实是唯一指定的运动误差。结果表明，体现这一假设的特定模型能够解释扫视的许多其他特征，也可以解释动态过冲和微扫视振荡（见附录）。
418 VAN GISBERGEN, ROBINSON, AND GIELEN neurons could be driven by a motor error signal, which is the difference between instantaneous eye position, obtained by monitoring an efferent signal, and desired eye position in the orbit, specified by higher visual or cognitive centers. Burst neuron discharge rate was plotted against the difference between instantaneous and final eye position during a saccade, suitably corrected for the time shift of the final common path. In 89% of the horizontally acting burst neurons examined, the relationship followed a common trajectory for saccades of all sizes in the on-and off-direction. For these cells, burst discharge rate may indeed be uniquely specified by motor error. It was shown that a specific model embodying this hypothesis, which is able to account for many other features of saccades, could also account for dynamic overshoot and microsaccadic oscillations (see APPENDIX).
