Abstract

Statistics of natural scenes are not uniform-their structure varies dramatically from ground to sky. It remains unknown whether these nonuniformities are reflected in the large-scale organization of the early visual system and what benefits such adaptations would confer. Here, by relying on the efficient coding hypothesis, we predict that changes in the structure of receptive fields across visual space increase the efficiency of sensory coding. Using the mouse (Mus musculus) as a model species, we show that receptive fields of retinal ganglion cells change their shape along the dorsoventral retinal axis, with a marked surround asymmetry at the visual horizon, in agreement with our predictions. Our work demonstrates that, according to principles of efficient coding, the panoramic structure of natural scenes is exploited by the retina across space and cell types.

摘要

自然场景的统计数据并不均匀——它们的结构从地面到天空差异巨大。目前尚不清楚这些非均匀性是否反映在早期视觉系统的大规模组织中,以及这种适应会带来什么好处。在这里,我们基于有效编码假说预测,跨视觉空间的感受野结构的变化会提高感觉编码的效率。利用小鼠(Mus musculus)作为模型物种,我们发现视网膜神经节细胞的感受野沿着背腹视网膜轴改变形状,在视觉地平线处呈现明显的环绕不对称性,这与我们的预测一致。我们的工作表明,根据有效编码的原则,视网膜在空间和细胞类型上利用自然场景的全景结构。
