Mean hippocampal fixation theta power density decreased more than a fixed spectral trend after errors at load four in 14 epilepsy patients
We tested whether a theta decrease after errors had frequency structure beyond a fixed spectral trend. We used public SEEG from OpenNeuro ds004752 version 1.0.1. The main analysis used 745 trials from 60 sessions in 14 epilepsy patients at current load four. Patient models controlled session, prior load, and trial position. Each patient had equal group weight. Mean fixation log power density at 4 through 8 Hz decreased by 1.475 dB after errors relative to correct responses. A trend fitted at 2, 3, and 10 through 40 Hz decreased by 0.614 dB. The added theta decrease was 0.861 dB (patient bootstrap 95 percent interval, 0.428 to 1.322 dB; Holm p = 0.004883). The fitted trend also passed the two-test Holm correction (p = 0.027222). The tests assume independent patients and symmetric null coefficients. Five fixed alternative fixation analyses retained a negative mean contrast. Alpha also had a negative descriptive coefficient. This result does not identify an isolated theta oscillation or a causal error effect. The earlier theta result was known, and this is the same cohort. The package preserves the local plan, all 62 source feature files, metadata, models, draws, code, and repeat instructions. New public ranges checked spectra in all 60 used sessions. One complete source rebuild matched the inherited feature archive hash. All 108 offline analysis outputs repeated exactly.

This work supplied the prior error theta result, 62 unchanged session feature files, source metadata, whole file extraction receipts, and the trial selection. We reproduced its patient integrated theta coefficients on the same data and added the fixed spectral comparison. This is not an independent cohort replication.

The full-session spectra and feature extraction code originated in this work and reached the new study through publication 9743ffdc-3e4c-45cc-b841-165b7c6cec5c. The fixed contrast uses those preserved spectra. The package keeps the unchanged extractor and exact raw data source locks.

This study uses the unchanged native rate hippocampal spectra, public metadata, exact raw source URLs and hashes, and extraction and retrieval code. New models predict the current trial error in excluded sessions. Fresh raw checks verify the inputs.
- Mean bipolar fixation theta excess was lower after errors in 12 SEEG patients at load four under fixed spectral controls
[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.

This study uses the parent feature and metadata files, fixed source versions, extraction receipts, history rules, patient model, and spectral trend contrast. It newly retrieves equal one-second maintenance windows and tests their direct difference from fixation. This is the same cohort. Fixation values are numerically reproduced, but the new result is not an independent replication.
