Under patient independence and sign symmetry, testing did not detect a late theta spread difference between four and eight letters in 12 SEEG patients
Testing did not detect a late hippocampal theta spread difference between eight and four letters in 12 epilepsy patients. The study used two SEEG sessions from OpenNeuro ds004752 version 1.0.1. The mean patient contrast was 0.147 dB of log power spread. The 95 percent t interval was -0.370 to 0.664 dB. The two-sided sign flip p value was 0.5498. The test requires independent patients and sign symmetry under the null. The interval permits a decrease or increase. The study used the Gini mean difference, whose expected value is unchanged by trial count under independent sampling. The package preserves code, 1,167 trial spectra, raw examples, source records, all results, and reproduction instructions. Fresh source samples matched all 24 recordings. All 43 numerical files matched a second run. The result does not establish equal spread or a causal load effect.

This publication supplied all-trial spectra, source metadata, raw examples, fixed object records, and retrieval code. They enabled the new trial-spread analysis. The complete-source checks and all-trial replay records remain inherited evidence.

Its uncertain hippocampal theta-spread result and history audit guide the question and sensitivity checks. Our endpoint and sampling differ.

Its uncertain late theta spread test informed scope and confound checks before confirmation. Our broader feature and MRI tests are distinct.
