Here we investigated whether such stability can be mediated, in part, via prediction-error signaling by neurons processing post-saccadic visual images. We specifically recorded from foveal superior colliculus (SC) neurons when a visual image only overlapped with their response fields (RF’s) after foveating saccades but not pre-saccadically. When we rapidly changed the target features intra-saccadically, the foveal neurons’ post-saccadic visual reafferent responses were elevated, even though the neurons did not directly sample the pre-saccadic extrafoveal target features. This effect did not occur in the absence of saccades, and it also scaled with the extent of the introduced intra-saccadic image feature discrepancies. These results suggest that foveal SC neurons may signal a trans-saccadic prediction error when the foveated image stimulating them is inconsistent with that expected from pre-saccadic extrafoveal representations, a potential perceptual stability mechanism.\nCompeting Interest Statement\nThe authors have declared no competing interest.\nFootnotes\n- Added neural analyses of the population temporal dynamics - Added behavioral analyses on eye speeds, post-saccadic drifts, and catch-up saccades","source_license":"CC-BY-4.0","license_restricted":false}
