论文摘要
我们分析了视网膜中侧向连通性（无链氨酸细胞和间隙连接）对运动预期的潜在影响。我们的主要结果是，在纸触发中分析的一波活性可以增强局部增益控制所提供的预期机制[8，17]。我们通过在实验文献中研究的两个示例来说明这些预测：差异运动敏感细胞[1]和方向敏感细胞，其中方向灵敏度从间隙连接连接中的不对称性继承[73]。我们最终提出了对2D视觉输入的视网膜响应的重建，以评估模型在三种不同的2D刺激的情况下预测运动的能力。
We analyse the potential effects of lateral connectivity (amacrine cells and gap junctions) on motion anticipation in the retina. Our main result is that lateral connectivity can-under conditions analysed in the paper-trigger a wave of activity enhancing the anticipation mechanism provided by local gain control [8, 17]. We illustrate these predictions by two examples studied in the experimental literature: differential motion sensitive cells [1] and direction sensitive cells where direction sensitivity is inherited from asymmetry in gap junctions connectivity [73]. We finally present reconstructions of retinal responses to 2D visual inputs to assess the ability of our model to anticipate motion in the case of three different 2D stimuli.
