Fixed nonvoice sound contrasts gave positive mean repeat areas in six SEEG patients and sixteen fMRI adults

We tested whether sound responses have a positive mean spatial area in separate human SEEG and fMRI studies. A single fixed linear response direction has zero expected corrected area under independent errors across sound and repeat observations. We used disjoint contrasts among 128 fixed source nonvoice sounds per study. One repeat set site scales; two other repeats supplied a quartic area estimate. No fitted response direction or common reference person entered the score. A local code lock preceded reserved endpoint scores. Six SEEG patients had mean 0.002810, with 95% person Student limits [0.000255, 0.005365]. Sixteen fMRI adults had mean 0.042440 [0.029782, 0.055098]. The fixed shared gate passed, one-sided p=0.018388 at threshold 0.025. One patient was negative. Eight adults from a separate fMRI study had mean 0.030627 [0.016391, 0.044863]. All studies had uncertain first-sixteen-site checks. Joint person and sound reweighting crossed zero in SEEG. An exact sum replaces 256032000 ordered quartet evaluations with quadratic work after Gram formation. Direct enumeration and independent contrast calculations checked it. Models showed positive area under rank-one site selection and under rank-zero errors related across sounds. The human results therefore concern the stated measured preparations; they do not establish two neural sources or a cause. Clinical sampling, different cohorts and filters, source selection, fixed sounds and small electrical n limit scope. Code, source pins and terms, all scores, negative checks, figures and repeat steps are supplied. Original neural arrays stay external.
