Abstract
OBJECTIVES: To evaluate the use of 75 auditory clicks rather than the usual 100-256 for production of the vestibular-evoked myogenic potential (VEMP) response and to assess if the VEMP correlates with measures of cochlear function such as hearing loss (decibels on pure-tone testing) or auditory brainstem response (ABR). SUBJECTS AND METHODS: Testing of the VEMP was carried out on 24 subjects: 7 normal individuals and 13 hard-of-hearing patients, 2 patients with known vestibular lesions, 1 with profound sensorineural hearing loss and 1 patient with unilateral acoustic neuroma prior to resection. The recording was performed using a conventional ABR machine. Using 75 refraction clicks as auditory stimuli, VEMP responses were measured from a surface electrode applied to the sternocleidomastoid muscle. The 75 responses were averaged. RESULTS: A consistent unilateral biphasic response, the first negative and the second positive (nI, pII), was elicited from 39 of 40 ears (7 normal and 13 hard-of-hearing subjects with no known vestibular dysfunction). No statistical difference was found between the right and left ear responses for nI or pII wave latencies. Two patients with loss of peripheral vestibular function showed no VEMP responses on the affected side. The responses, however, were elicited bilaterally in a patient with congenital profound sensorineural hearing loss. In addition, ABR latencies did not correlate with VEMP latencies. CONCLUSION: Clear VEMP responses were elicited by using only 75 auditory clicks. This shortens the testing time and facilitates the procedure for the tested subject. Our data also indicate that the VEMP is generated secondary to auditory stimulation of the vestibular end organs (specifically the saccule) and does not correlate with cochlear function.

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
