Adaptation is ubiquitous in sensory systems. Sensory neurons change their activity depending on the past stimulus history, which they integrate at various timescales. Short- and long-term adaptations have been mostly studied using simple, artificial stimuli, but rarely with natural scenes. Even at the level of the retina, it is unclear how these adaptive processes impact ganglion cells, the retinal output, and how they change their feature selectivity to natural scenes as a function of the recent stimulus history. This raises a major challenge for our understanding of how ganglion cells proce
