Modeling the Nonlinear Context Dependency of the Neural Integrator in the Vestibuloocular Reflex
Bibliographic record
Abstract
A neural integrator (NI) is presumed to exist in the oculomotor system to assist in numerous tasks such as maintaining gaze on imaginary targets in the dark. It is shared by all ocular reflexes including the vestibuloocular reflex (VOR). It has been widely accepted that the NI acts as a "perfect" integrator even in the dark with time constants as large as 1950s. However, the NI time constant is often less than ideal and its value can also be dependent on context [W. W. P. Chan and H. L. Galiana, "Integrator function in the oculomotor system is dependent on sensory context," J. Neurophysiol., vol. 93, pp. 3709--3717, Feb. 2005.]. In this paper, a nonlinear feedback model is postulated to model the context-dependent properties of the NI. Algorithms are first developed and validated to fit both linear and nonlinear NI models to experimental data in the presence of ocular nystagmus. Preliminary results indicate that even normal subjects can have a nonlinear VOR and NI.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
