Abstract
The aim of this study was to compare multimodal information processing in the somatosensory and auditory cortices and related multimodal areas in musicians (trumpet players) and non-musicians. Magnetoencephalographic activity (MEG) was recorded in response to five stimulus conditions from 10 professional trumpet players and nine musically untrained control subjects. Somatosensory and auditory stimuli were presented alone or in combination. Our data suggest that musicians, in general, process multisensory stimuli differently to the control group. When stimulating the lip in professional trumpet players, a multimodal interaction (expressed as difference between the multimodal response and the sum of unimodal responses) in the corresponding somatosensory cortex showed a positive peak at 33 ms, which was not found in the control group. Conversely, the control group shows a significant interaction of opposite polarity around 60-80 ms. We suggest that training-induced reorganization in musicians leads to a qualitatively different way to process multisensory information. It favors an early stage of cortical processing, which is modified by the connections between multimodal and auditory neurons from thalamus to primary somatosensory area.

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
