Early beta coupling did not lower mean recall forecast error in 13 SEEG patients under assumed source trial order
We tested whether early beta coupling improves later recall forecasts beyond task context, signal power, and channel availability. We used OpenNeuro ds006136 v1.0.1: 13 patients, 14 sessions, and 143 released SEEG channels. We joined channels by source trial ID and assumed that increasing IDs give task order. Each session used its first 65% of matched trials for training and its last 35% for testing. There were 751 test trials. Eleven patients had a retained frontal-temporal pair. Adding beta coupling raised mean patient Brier error from 0.179632 to 0.180940. Mean gain was -0.001308; the descriptive 95% patient bootstrap interval was [-0.005296, +0.002441]. Five patients improved, six worsened, and two had no pair and no change. All fixed secondary comparisons also had negative mean gains. The interval permits both benefit and harm. The package adds a compact spectral dataset and a reproducible forecast test. The study reuses a processed epilepsy cohort. It does not establish an online readout, causal brain coupling, or a stimulation benefit.

This work uses the parent EDF retrieval and power extraction code, power tables, source manifest, and task-history design. Fresh raw extraction reproduced the power tables. The new test adds beta coupling and preserves the same later-trial split. The cohort is reused.

- usesAdded frontal and temporal power envelope correlations raised mean recall forecast error in fixed logistic readers for 11 SEEG patients under assumed source trial order
We read its same-band beta coherency test after calculating the new envelope results. We use it to describe prior work on the same cohort and the difference in the tested signal measure. It does not provide independent confirmation of the present result.
- usesEarly delay power gave no mean recall forecast gain in 13 SEEG patients excluded from fitting under assumed trial order
This publication supplied power features, source metadata, a source manifest, and extraction code. We checked the raw signal hashes, rebuilt the features, and added a test that excludes each target patient from fitting.
- usesBeta episode occupancy raised mean recall forecast error for 13 SEEG patients under assumed source trial order
The known result on early beta coupling in this same cohort helped select this exploratory question. No code or numerical output from that result is reused. This study is not independent confirmation in a new cohort.
