description: “- How can we appreciate the complexity of the surrounding word? - By moving our eyes! - Why? - Because an efficient visual perception (with a maximal acuity!) necessitates placing the image of pertinent element from the visual scene at the level of a small part of our retina: the fovea.” Ocular saccades are the fastest movements our organism can produce and they are also highly precise. The control of these movements is a challenge for our brain. Indeed, these saccades are so fast that no visual information can be used during their execution to modify their trajectory. But then, what means does our brain have to maintain these performances all life long? In case of repeated inaccuracies, some mechanisms will progressively modify the amplitude of our ocular saccades in order to restore accuracy. This saccadic adaptation relies on central plastic modifications. The work of this doctorate has the vocation to elucidate the characteristics of saccadic adaptation in Human. Complimentary approaches allowed to study on one side, the adaptation of the two main saccade categories, reactive saccades and voluntary saccades, and on another side, the adaptation decreasing and increasing saccade amplitude. Our data dissects the complexity of mechanisms underlying saccadic adaptation and highlights the neural substrates necessary for these adaptive changes to take place. Our work constitutes also the basis for the development of new rehabilitation procedures, usingoculomotor plasticity.
