Identification and analysis of neurophysiological markers of disorders of consciousness based on auditory ERPs
Bibliographic record
Abstract
The identification and exploration of reliable features of conscious processing is a key area of research that is integral to the study of disorders of consciousness. In this study, two different auditory ERP paradigms were designed: the semantic paradigm, which focuses on brain activities related to language comprehension, and the non-semantic paradigm, which focuses on non-verbal sound processing. Data from the two paradigms were integrated and analyzed through a joint paradigm analysis approach to more comprehensively assess the level of consciousness in patients with disorders of consciousness. Based on a review of current theories, such as information theory and brain network theory, we identified three feature dimensions, namely, power spectral density metrics, brain network graph theory metrics, and entropy-like metrics, to explore the feature differences among patients with different levels of consciousness. Entropy class metrics play an important role in distinguishing patients with different levels of consciousness. Through data fusion and feature synergy, the joint paradigm analysis method can more comprehensively assess the level of consciousness of patients with disorders of consciousness than the single paradigm analysis method, providing a more accurate and reliable neurophysiological basis for the diagnosis of disorders of consciousness.

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.
