Musical training modulates encoding of higher-order regularities in the auditory cortex
Bibliographic record
Abstract
We investigated the effect of long-term musical training on the time course of development of neuronal representations within the auditory cortex by means of magnetoencephalography. In musicians but not in nonmusicians, pre-attentive encoding of a complex regularity within a tone sequence was evident by a constant increase of the pattern mismatch negativity within < 10 min. The group difference was more pronounced in the left hemisphere, indicating stronger plastic changes in its structures supporting temporal analysis and sound pattern encoding. The results suggest an effect of long-term musical training on short-term auditory learning processes. This has implications not only for cognitive neuroscience in showing how short-term and long-term neuronal plasticity can interact within the auditory cortex, but also for educational and clinical applications of implicit auditory learning where beneficial effects of (musical) experience might be exploited.

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.
