After correct responses, fixation theta power was lower after eight than four letters in 14 SEEG patients with the stored reference and linear trends
We tested whether fixation theta power was associated with the preceding recorded memory load in OpenNeuro ds004752 version 1.0.1. The sample had 2561 selected trials from 62 sessions and 14 patients with epilepsy. Each trial followed a correct recorded response. With the stored reference and linear session trends, the mean eight-letter minus four-letter contrast was -0.353 dB. The 95 percent patient bootstrap interval was -0.659 to -0.084 dB. The exact two-sided sign-flip p value was 0.0267 under independent patients and symmetric effects under the null. Common average reference and quadratic trend intervals included zero. None of eight secondary tests passed Holm correction. The study is an exploratory association and does not establish a cause or a theta-specific mechanism. The package preserves a 3053-row history table, source features, code, provenance, results, and reproduction commands. Fresh raw powers from 14 sessions matched the reused features. A separate offline run reproduced all 18 numerical result files exactly.

This publication supplied all 62 verified feature files, the native EDF extractor, and source provenance. The present study checks their archive hashes and tests preceding recorded load during fixation. It uses the same patients and is not an independent patient replication.

This earlier maintenance study compared reference choices in the same dataset. Its scope helped avoid a duplicate maintenance question and supported the planned reference checks. No feature file or analysis code was copied from this publication.

- usesMean hippocampal fixation theta was lower after errors at load four in epilepsy patients with session and prior load controls
We read its preceding-load result after our primary effect. It supplied context for fixation history dependence. Our model held preceding load fixed and tested preceding response outcome.
- usesThe prior-load estimate for adjusted hippocampal theta change included zero in 14 SEEG patients
The earlier prior-load fixation result informed the new phase question. Its trial-history rules and patient model are reused.
- The adjusted hippocampal fixation theta estimate for prior memory load had an interval that included zero in 14 SEEG patients with linear session trends
[Legacy relation: reproduces] The integrated fixation theta coefficient and exact patient test match the earlier result. The history rules and patient session model are reused. This is a check in the same patients. It is not an independent replication.
- usesFixed linear models showed no clear load ranking gain from late maintenance power changes across sessions in 14 SEEG patients
Its fixation association with preceding load helped motivate our recorded-history baseline. We did not use its result files. This analysis uses the same public patient sample.
- usesThe 95% interval for error prediction gain from fixation theta included zero in a fixed model tested on numbered session halves from 14 SEEG patients
Its same-cohort fixation result tested the preceding memory load. This context informed the prior-load controls. Its fitted coefficients and outcome estimates did not enter the new prediction models.
