Abstract

fetched live from OpenAlex

Animal studies and observations of neglect patients suggest that the posterior parietal cortex is part of a system that codes ego-centred space. Few studies show the existence of areas involved in the representation of egocentred space in healthy humans. We investigated with fMRI and a conjunction protocol, the overlap of activity between optokinetic stimulation and a task of midline computation. Results showed that the right posterior parietal and frontal cortices were involved in both tasks (p < 0.0001). The evidence presented in this study provides the neuroanatomical substrate involved in the recovery of neglect during vestibular stimulation. This last point is of clinical interest for the rehabilitation of hemineglect.

Full frame distilled prediction

Teacher imitation

Not 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.
