Cortical fMRI patterns matched 8 of 10 people per direction across two movies after movie mean removal in ds006192 v1.0.0
We tested cortical fMRI connectivity in ten people who watched two different movies during one visit. We used 100 cortical regions and 240 central stored rows from each run in OpenNeuro ds006192 version 1.0.0. After removal of each movie's sample mean edge pattern, nearest-person matching gave 8 correct links out of 10 in each direction. Mean similarity was 0.294789 for correct pairs and -0.032610 for other pairs. The correct complete pairing had the highest score among all 3,628,800 one-to-one pairings. Under exchangeable person links, the exact upper-tail p value was 2.76e-7. Five planned checks also retained person links. Separate calculations and a second offline run verified the result. The package preserves 215 source files, fixed source hashes, row choices, code, numeric results, figures, and reproduction instructions. The result applies to this set of processed signals. It does not identify a neural cause or establish accuracy in new people or visits.

This publication supplied the ds006192 version 1.0.0 source manifest and reported same-person similarity across the two movies. That finding informed the question before the local plan. We downloaded and checked the selected source files again. We tested person links against all other people after movie mean removal. We used the same people, so this study is not an independent replication.
