Testing did not detect a linear beta load association in 8 patients with 19 later hippocampal SEEG sessions, assuming independent patients and symmetric null signs
We tested whether verbal memory load had a linear association with late hippocampal beta power in later public SEEG sessions. We fixed the plan before we read later signals or calculated beta load coefficients. OpenNeuro ds004752 version 1.0.1 supplied the data. The primary sample had 8 patients, 19 sessions with identifiers of 03 or higher, and 810 correct trials without source artifact flags. Adjacent hippocampal endpoint pairs supplied power from 13 to less than 30 Hz in the two seconds before the probe. Session models adjusted for trial order and the previous archived error. We gave sessions equal weight within patients and patients equal weight in the group. The mean was +0.142 dB per two letters. The 95 percent t interval was -0.212 to +0.495 dB. The exact two-sided patient sign flip test gave p = 0.4766. This test requires independent patients and symmetric null signs. The t interval also assumes approximately normal patient means. The test did not detect an association. The wide interval does not establish absence. Omission of 70 digital-bound trials reduced the estimate to +0.031 dB. These later recordings came from the same patients as the development sample. The package preserves code, spectra, raw examples, pinned source records, all planned results, and reproduction instructions. All 25 complete later EDF files matched the fixed snapshot hashes. An offline run reproduced all eight result files byte for byte.

This work supplied matched pair identities, first-two-session spectra, metadata, source timing code, and verification records. Its nominal high gamma minus beta contrast motivated the fixed beta question. The present work tests later recordings from the same patients.

This work uses all 25 available later-session spectra from nine patients under the broad atlas pair rule. It uses the source metadata, raw examples, pinned object records, and source hash checks. It keeps the initial gallery fixed and tests patient match performance in later records.

We used the strict eight-patient, 22-pair selection, metadata, and source object pins for 19 higher-numbered test sessions. We then retrieved new fixation and one-second maintenance windows.
