The late maintenance hippocampal theta load estimate had a bootstrap interval that included zero after correct responses in 14 patients
We tested eight letters minus four letters during late memory maintenance in OpenNeuro ds004752 v1.0.1. We used all 62 sessions with source hippocampal SEEG labels from 14 patients with epilepsy. The main rule retained 2,561 trials after a correct response. The mean 4 to 8 Hz power effect was +0.034 dB. Its 95% patient bootstrap interval was -0.345 to +0.571 dB. The exact two-sided sign-flip p value was 0.9590 under independent patient effects and a symmetric null. Five patient estimates were positive and nine were negative. This result does not establish a consistent load increase. It does not prove zero effect. All planned reference, trial, and fixation checks are reported. The source labels also show that 275 of 299 trials after errors have four letters. The package preserves features, trial history, patient estimates, resampling distributions, source metadata, hashes, retrieval recipes, code, and independent numerical checks. A repeated analysis produced 16 identical result files.
