Scores for three sound groups were positive in six SEEG patients and 24 fMRI adults; the shared rule failed

We tested whether three sound-group mean response patterns need more than one fixed linear spatial direction. Separate public studies supplied human SEEG high-gamma and BOLD fMRI. Two patients and four MRI adults supplied pilot data. A local code lock preceded scores in six other patients and 16 other adults. Eight adults from a second fMRI study supplied an added check. The groups contained 128 nonvoice sounds, nine other human voices and 28 speech or song sounds. One repeat set scales and axes. Two other repeats tested a signed minor. All 30 person scores were positive. The SEEG mean was 0.11420, with 95% person Student limits [-0.01503, 0.24344]. The two MRI means were 0.30431 [0.24055, 0.36808] and 0.32785 [0.25533, 0.40036]. The single shared rule also required a positive electrical score difference from pre-onset data. Its combined one-sided probability was 0.03651, but the required positive lower interval limits failed. Joint sound and person resampling also crossed zero in SEEG. Thus the fixed test did not confirm cross-modal generalization. The established minor has zero expected value for a rank-one mean under independent zero-mean full repeat errors. Source selection across repeats can break that model. A constructed rank-zero screen gave mean 0.45832. A nonlinear scalar input also gave a positive score. Neither neural rank nor a common cause is established. The package gives code, source pins and terms, all outcomes, figures, audits and repeat steps. Original neural arrays remain external.
