WebSaccades are rapid eye movements that shift the image on the retina. How visual systems differentiate motion of the image induced by saccades from actual motion in the environment is not fully understood 2. Here we discovered that in mouse primary visual cortex (V1) the two types of motion evoke distinct activity patterns. Webhuman information processing. Following a long tradition in psychology and neuroscience, visual information processing can be described in terms of a two-level model (e.g. [7], [8], [9]). At the first, preattentive level, objects are dynamically localised in the 3D environment – hence the other name for the level, which is ‘ambient’.

WebMar 15, 2024 · During the active visual exploration of the world rapid eye movements, so-called saccades, shift the visual image across the human retina.
