Motivational modulation of endogenous inputs to the superior colliculus
Bibliographic record
Abstract
Proper initiation of saccadic eye movements depends on an intricate balance between exogenous and endogenous control mechanisms. The superior colliculus (SC) is a major site of signal integration that has been shown to drive the initiation of saccades in the brainstem. Previous work has shown that a winner-take-all mechanism implemented with a continuous attractor neural network (CANN) can explain and reproduce a multitude of behavioural findings, including the gap effect and the production of express saccades by K. Kopecz (1995) and by T.P. Trappenberg (2001). This investigation advances the CANN model of saccade initiation in several important ways in order to account for trial by trial adaptation of saccadic reaction times in a biologically plausible manner. A key hypothesis is that endogenous inputs to the intermediate layer of the SC can be adapted through motivationally-based feedback from other areas of the brain such as the basal ganglia or higher cortical areas.

How this classification was reachedexpand
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.
