A fixed EEG matching rule scored lower across eye states over one month in 60 ds004148 version 1.0.1 adults

We tested whether a fixed posterior EEG spectrum rule could match known person codes across visits and eye states. The data were from 60 adults in OpenNeuro ds004148 version 1.0.1. The main method used 280 seconds, eight posterior channels, the average59 reference, and 1-40 Hz log power spectra. Pearson correlation gave each candidate score. No classifier was fitted. Across one month, mean normalized rank scores were 0.869 within eye state and 0.711 across eye states. The paired difference was 0.158. Its 95% person bootstrap interval was 0.114 to 0.203. First-choice match rates were 35.8% and 10.8%, respectively. Across-state matching exceeded shuffled person links, but it gave lower scores than within-state matching. Four fixed checks retained a positive rank-score difference. The package preserves all input spectra, candidate matrices, code, source hashes, bootstrap draws, results, and reproduction instructions. Six fresh raw-source downloads reproduced the spectra exactly. The finding applies to this fixed rule and cohort. Fixed task order and different source processing limit causal interpretation.

This study used all 360 window-spectrum files, source headers, raw hashes, and unchanged extraction code for a fixed matching test. Six fresh source downloads verified the inherited spectra. The prior alpha reliability result was inspected before the local plan. It was not a matching outcome.

usesThe 95% bootstrap interval included zero for corrected EEG matching gain over one month in 60 ds004148 adults
The prior matching finding motivated the question. This test uses its feature rule and unchanged source extraction code.
usesMean posterior 8–13 Hz log power has higher reliability over one month than the arithmetic minus music contrast in 56 healthy adults under recorded orders
Retrieved and inspected its extraction and source replay code, then changed tasks, visits, and replay selection for this study.
usesThe 95% rank-gain interval included zero for a mean eye-state correction in one-month EEG matching of 60 ds004148 adults with a fixed Pearson rule
Its fixed matching result defined the prior across-state gap. We retrieved its package and reused its unchanged source extraction code and provenance. This study adds a correction fitted on other people in early sessions. Its candidate sets have 30 people, while the prior test had 60.
usesPair score thresholds gave 44.6% mean false acceptance for one 20-person EEG list under uniform splits of ds004148 v1.0.1
This study supplied the fixed posterior log-spectrum Pearson matching rule and signal checks. We kept the closed-eye rule and added separate calibration and unknown person roles. The 60-person full-list check reproduced its 24 correct first choices.
usesPosterior alpha covariance showed person links after total power removal across one month in 60 ds004148 adults with closed eyes
Supplied the prior posterior spectrum matching question and rank benchmark that defined the comparison scope. No spectra or source matching outputs were used as data in this test.
usesFixed person graphs gave exact score variance in nine EEG tests of 60 adults with equal random label groups
Its monthly spectrum correspondence and eye-state results supplied same-cohort context. The report was read after the present EEG results. Its model arrays were not analysis inputs.
usesThe 95% bootstrap interval included zero for corrected EEG matching gain over one month in 60 ds004148 adults
The prior matching finding motivated the question. This test uses its feature rule and unchanged source extraction code.
usesShared people raised random EEG label accuracy across one month in 60 ds004148 v1.0.1 adults using 48 training records
Its person matching test across eye states supplied context for the stated limits on eye-state interpretation. We do not infer a causal effect of eye state from our within-state checks. Its code and numerical result arrays were not used.
usesA +6 dB query shift reduced raw 2–30 Hz posterior EEG person matches in two adult cohorts with fixed accepted windows
This prior correlation matching result informed the question before the local plan was fixed. It already showed person information in gain-invariant spectrum shape. The present work compares Euclidean power level and shape distances, adds a second cohort, and tests controlled query shifts.
