A five-finger order test with single-finger terms removed did not confirm a shared pattern in six ECoG patients and six fMRI adults

We tested whether five-finger response distances follow order on the hand after additive terms for each finger are removed. Separate public studies supplied cortical electrical recordings and 7 T fMRI. Development used two ECoG patients and one MRI adult. A local plan and code lock preceded scores in six other patients and six other adults. Mean alignment was 0.40790 and 0.61095. Their 95% person Student intervals were [-0.10119,0.91700] and [0.39052,0.83137]. The fixed shared rule failed because the electrical interval crossed zero. Five of six electrical scores and all six MRI scores were positive. Only two electrical people had positive scores in both chronological halves; all six MRI people did. Positive thumb-omission checks remain descriptive and do not replace the failed test. An exact check showed that the adjusted order numerator contains no middle-finger distance. The denominator still uses these distances. The 120 label orders give only 15 adjusted targets. A spatially centered pattern with one signal axis gives a perfect score. Thus this score cannot establish a detailed five-finger map even if its mean test passes. A separate calculation matched all 89 saved scores within 1.8e-15. A fresh source-file replay matched all fixed result tables and bootstrap arrays. The contribution is a method scope check and a complete benchmark with a failed shared claim, not a new positive neural relation. Separate cohorts and tasks, sparse clinical sampling, unequal sensing, source processing and six test people per modality limit scope. The package preserves code, source pins and terms, the local plan, all outcomes, figures and repeat steps. Original neural arrays remain external.
