Abstract
CONCLUSION: There appears to be a definite link between reorganization of the cortical tonotopic map and increased spontaneous firing rates. The results have implications for the reduction of noise-induced hearing loss and in the prevention of noise-induced tinnitus in humans. OBJECTIVES: To review animal and human studies related to neural correlates of tinnitus. Among those are increased spontaneous firing rate, enhanced neural synchrony, and reorganization of the cortical frequency-place (tonotopic) map. MATERIALS AND METHODS: To separate these issues one would want to have a situation where hearing loss is present but without reorganization of the cortical frequency-place map. For that purpose, noise-exposed cats were placed, immediately after the trauma and for at least 3 weeks, either in a quiet or in a high-frequency or low-frequency enriched acoustic environment. RESULTS: In exposed cats that were placed in the quiet environment there was an increase in spontaneous firing rate and synchrony of neurons in primary auditory cortex. In contrast, exposed cats placed in the high-frequency-enriched acoustic environment did not show any significant difference in spontaneous firing rate or synchrony compared to the non-traumatized controls.

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 it
