Mean bipolar fixation theta excess was lower after errors in 12 SEEG patients at load four under fixed spectral controls

We tested whether a known after-error fixation theta decrease remained under reference and session trend changes. We used public OpenNeuro ds004752 version 1.0.1 and a fixed spectral contrast. The planned bipolar check retained 12 epilepsy patients and 547 trials at current load four. Mean theta excess was 0.724 dB lower after errors than after correct responses. The descriptive 95% patient bootstrap interval was -1.172 to -0.304 dB. Separate linear and quadratic session trends retained negative means in the 14-patient primary sample. A later comparison used identical trials and controls across three references. All three mean coefficients were negative. Reference difference intervals included zero and did not establish reference equivalence. The primary contrast reproduced a same-cohort mean decrease of 0.872 dB in 14 patients. Its two-test Holm p was 0.003174 under independent patient and null sign symmetry assumptions. This is a conditional association in selected trials, without an identified error cause or local theta generator. The package preserves code, fixed source versions, features, model designs, resampling arrays, and reproduction commands. Fresh signal checks covered 60 sessions and all three native sample rates. One complete raw recording was retrieved and rebuilt exactly. Related reports, source reuse, the local plan, and the later descriptive comparison are disclosed.

    This publication supplied the fixed spectral contrast definitions and the 62-session feature archive. The present study applies those definitions to prior errors.

    Its raw extraction code, signal features, metadata, and fixed source receipts supplied the source measurements. They were retrieved through the spectral contrast publication. Fresh range checks and one full-file rebuild verified selected measurements.

    [Legacy relation: reproduces] The integrated theta coefficients reproduce all 14 earlier patient coefficients exactly. Both analyses use the same selected trial rows and controls. This is a same-data computational reproduction.

    The fixed contrast and planned control checks agree in direction with its negative same-cohort residual under different flanks. This is not an independent cohort confirmation. The related report was read after the initial fits and signal checks.

    [Legacy relation: reproduces] The 14-patient primary result reproduces its 10-20 Hz flank check at a mean excess of -0.872 dB. The source cohort and features are the same. Planned bipolar and separate session trend checks add evidence. The related report was read after the initial fits and signal checks.
