Sound relationships after category removal agreed between a fixed iEEG panel and eight fMRI adults
We tested whether sound relationships agree across human intracranial EEG (iEEG) and fMRI after category means and the mean across sites are removed. Separate public studies supplied 33 selected electrode response files, with 32 distinct profiles, and scan 3 from eight adults with 9,340 voxels. All 165 sounds aligned by source ID. A local plan fixed two tests before new geometry scores. Mean kernel correlation was 0.08963. Its exact category-preserving shuffle expectation was 0.006890. Excess agreement was 0.08274, with an approximate sound and fMRI person resampling range of 0.05351 to 0.11556. Removing one supplied acoustic kernel direction gave mean correlation 0.07403. All eight adults had positive scores in both tests. Each test had Holm p=0.0002 under synchronized sound-label shuffles. The acoustic-adjusted permutation is not an exact conditional test given continuous acoustics. An exact projection split shows why category centering can itself produce positive agreement. A source audit found one duplicate electrode file; keeping one copy gave means 0.09071 and 0.07517. Missing electrical patient labels prevent patient-level uncertainty or a new-patient claim in iEEG. The finding concerns this fixed electrical panel and separate BOLD records. It does not establish a common neural cause or a non-acoustic code. Source selection, unequal sampling, one sound set, and distinct measurement scales limit scope. The package preserves code, plans, source hashes and terms, all results, figures, numerical checks, and repeat instructions.
