Pooled insula high-gamma gave negative mean confidence prediction gains in 14 patients across five trial blocks
We tested whether pooled insula high-gamma improves confidence prediction beyond behavior. We used public processed SEEG data from OpenNeuro ds006253 release 1.0.3. A fixed anatomy rule retained 14 patients, 78 bipolar pairs, and 2,971 trials. Each neural window added one pooled feature to a fixed behavior model. Five consecutive trial blocks gave separate test predictions. Mean relative error gains were -0.51% before movement and -1.74% after movement. Both 95% patient bootstrap intervals included zero. Corrected tests did not show a reliable gain. Three planned checks also gave negative mean gains. This result applies to the tested pooled signals and models. It does not establish absence of confidence information in individual contacts. The study reused an existing cohort and feature recipe. It is not an independent patient replication. The package preserves code, features, anatomy decisions, predictions, source versions, hashes, figures, and instructions. A fresh source rebuild matched all features for 15 analysis patients.

This publication supplied compact high-gamma features, source tables, range maps, trial rules, and four retrieval scripts. We checked its file hashes and rebuilt source features. We added fixed insula pooling models and new validation. The patients are reused, so this study is not an independent patient replication.

- usesA fixed insular SEEG model lost its mean confidence prediction advantage when the penalty for all channels increased from 1 to 10 in 12 patients
We use the reported anatomy rule, cohort size, and model scope to compare related work found after our scores. Its 14-patient atlas rule differs from our 12-patient rule. We do not use its result files to fit our models or claim new patient evidence.
- usesAdding pooled insula high-gamma after movement increased mean error prediction loss in fixed block tests for 14 SEEG patients
This work supplied compact signal features, source tables, anatomy matching, and the trial block splitter. The new study reused its strict 14-patient cohort and tested the released error label.
