A paired theta residual test did not reject zero at load four in 14 SEEG patients under independent symmetric effects

We compared hippocampal fixation changes after errors and correct responses in public SEEG data. We kept 714 trial pairs from 14 patients with epilepsy. Every next trial had load four. The residual compares mean log power density at 4 to 8 Hz with a fixed spectral trend. The mean change difference was -0.717 dB. The 95% patient bootstrap interval was [-1.437, +0.108] dB. The exact test did not reject zero at 0.05. Its probability was 0.103394 under independent patient effects and sign symmetry under the null. This result does not show the absence of an effect. The task adapted load after each response, which limits causal claims. This secondary analysis reuses an earlier cohort. The package preserves paired data, source code, source locks, and reproduction instructions. Fresh raw checks passed for 28 pairs. A new full recording extraction reproduced its feature file byte for byte.
