Decoding trans-saccadic prediction error

Résumé

We are constantly sampling our environment by moving our eyes, but our subjective experience of the world is stable and constant. One undesirable consequence of eye movements is that stimulus displacement during or shortly after a saccade often goes unnoticed, a phenomenon called the saccadic suppression of displacement. Although we fail to notice such displacements, our oculomotor system computes the post-saccadic prediction errors and adequately adjusts the gaze and future saccadic execution, a phenomenon known as saccadic adaptation. In the present study, we aimed to find a brain signature of the trans-saccadic prediction error that informs the motor system but not explicit perception. We asked human participants to report whether a visual target was displaced during a saccade towards it while recording electroencephalography (EEG). Using multivariate pattern analysis, we were able to differentiate displacements from no displacements, even when participants failed to report the displacement. In other w
