Abstract
Your eyes are probably performing saccades scrolling on the screen, or on the page you printed out to read the abstract of this thesis. Yet you do not have the perception that they are moving, you do not realize what happens during these movements, your perception is remaining stable, you have perfect control of your visual scene. This experienced stability is partially accompanied by an impairment of the visual system’s sensitivity, a phenomenon known as saccadic suppression. It has been documented that this phenomenon already starts at the retinal level and it is supported by three mechanisms. Two of them have been hypothesized to be mediated by lateral networks of retinal inhibitory interneurons.
More precisely by wide field amacrine cells' and horizontal cells' networks
