Tests did not detect beta density or excess change from fixation to late maintenance in 14 hippocampal SEEG sessions with stored reference under sign symmetry
We tested hippocampal beta change from fixation to late verbal memory maintenance. We used public OpenNeuro ds004752 version 1.0.1. The sample had 14 first sessions, 96 source contacts, and 563 retained trials. The primary tests used the stored reference and gave each patient equal weight. Mean beta log density changed by +0.138 dB (95 percent patient interval: -0.198 to +0.569). Fixed beta spectral excess changed by +0.109 dB (-0.112 to +0.339). Both Holm p values were 0.758. The tests assume independent patients and sign symmetry under the null. The results do not establish equivalence. Planned common average and bipolar checks gave larger density changes, but their excess intervals included zero. The package preserves source inputs, source hashes, code, all results, and a recipe to check the full public recordings. This is a new analysis of an existing epilepsy cohort.

We reused all 14 first session spectra, raw prefixes, and source metadata. We adapted its prefix reader and used its fixed spectral contrast approach for beta.

The earlier beta load result gave context. This study tests a different contrast: late maintenance minus fixation.
