Evolution has equipped vertebrates and invertebrates with neural circuits that selectively encode visual motion. In both flies and mice, early visual circuits separately detect the movement of light and dark edges. Strong parallels have been noted between the two systems in their anatomy, circuitry, and the suite of computations that they perform. However, because their direction-selective cells have different morphologies and employ different neurotransmitters and receptors, the similarities between them exist not at the molecular level, but at the algorithmic level. While similarities in the

Visual coding is a highly dynamic process and continuously adapts to the current viewing context. At early stages of visual processing, adaptation was generally studied without considering behavioural contexts. However, we recently learned that locomotion and arousal strongly modulate visual processing, even at the retina level. Here, we aim to understand how locomotion impacts visual adaptation in the superior colliculus (SC), the most prominent visual centre in mice, which integrates retinal input in its superficial layers and performs sensorimotor transformations in its deeper layers. We r
