With mean EEG reference, the closed-minus-open alpha persistence interval was positive in ds007176 and included zero in ds004148 for 60-second records

We tested whether posterior 8-13 Hz window power had more time persistence in closed-eye than open-eye records. We used source seconds 10-70, four-second windows, mean EEG reference, and fixed quality rules. The score is a normalized mean square successive-difference ratio. Its expected value is zero under a uniform permutation of accepted values at fixed time slots. In 59 ds004148 adults, the mean closed-minus-open score was 0.018, with a 95% person bootstrap interval of -0.042 to 0.078. In 38 ds007176 adults, it was 0.127, with an interval of 0.040 to 0.217. The fixed rule did not support a shared direction across cohorts. This does not show equal persistence. The longer ds004148 analysis had a positive interval. The supplied ds007176 reference gave an interval that included zero. Source order, artifact processing, and filter segments limit interpretation. CE and OE eye-state meanings in ds007176 are a source-label assumption. The package preserves 516 spectra, all planned results, code, provenance, a proof, and reproduction commands. Separate calculations checked every score and bootstrap summary. Four new complete raw replays matched every array exactly.

    Its comparison of adjacent and dispersed alpha samples led to the new normalized persistence question. The new study tests a different score and a separate cohort.
