How anticipatory remapping along the saccade direction predicts peri-saccadic biphasic mislocalization
Bibliographic record
Abstract
When we view the world, we move our gaze to bring light from different parts of the scene to the fovea. A given static stimulus in the visual scene therefore falls on different parts of the retina before and after a saccade. It has been shown that neurons in many visual and oculomotor “priority-map” brain areas respond to stimuli appearing before the saccade at the spatial location that their receptive field will occupy after the saccade, as if they are anticipating the consequences of the saccade. In a separate line of work, psychophysical studies have shown that stimuli flashed around the time of a saccade are systematically mislocalized in various characteristic patterns --- one of these is a biphasic pattern where flashes right before a saccade are mislocalized in the saccade direction and flashes right after a saccade are mislocalized opposite to the saccade direction. The anticipatory remapping along the saccade direction and the mislocalization along the saccade direction have been suspected to be linked, but there has been no explicit model of how they might be linked and some studies have called this connection into question. Here, we present a circuit model that shows how anticipatory remapping along the saccade direction predicts biphasic mislocalization of brief peri-saccadic flashes similar to that seen in empirical data. The mislocalization, rather than being an artifact of the remapping, is a result of incomplete remapping right before the saccade and residual remapping after the saccade. Smaller magnitudes of remapping before the saccade lead to larger forward mislocalization of pre-saccadic flashes, and smaller magnitudes of remapping after the saccade lead to smaller backward mislocalization of post-saccadic flashes. The model is consistent with the known physiology of RF remapping and trans-saccadic information transfer and makes clear predictions regarding the dynamics of RF remapping and trans-saccadic response updating for task-relevant stimuli that can be tested in future experiments. To the extent that RF remapping mechanisms along the saccade direction impact the same representations that may be used for the spatial localization of peri-saccadic flashes, they predict a biphasic mislocalization pattern for peri-saccadic flashes that is similar to what has been shown empirically.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
