Independent contact phases gave median gamma network stability above 0.96 in models from two SEEG rest records
We tested whether a stable bipolar SEEG network can occur without dependence between contact phases. We used 240 seconds from each of two public rest records in OpenNeuro ds005670 version 1.0.0. We kept each contact's gamma spectrum and used independent phases before we formed bipolar channels. Median network stability was 0.965 and 0.980 across two 120-second periods. Each result used 500 model draws. Recorded stability was 0.970 and 0.830. Tests that excluded shared-contact edges found stable recorded dependence. Network stability alone did not establish dependence between stored contact phases in this setting. The package provides exact selected samples, source hashes, an audit method, code, and three figures. No BCI task or stimulation outcome was tested.

We reused its source hash list, retrieval code, and metadata audit for ds005670 version 1.0.0. We retrieved both full records again and checked fresh metadata. We used a new selection based only on labels and metadata.

We used its contact-phase control rule and exact covariance center. We applied them to network stability across separate periods in two other rest records.

- usesIndependent contact models gave unequal bipolar prediction gains at 20 ms with 100 ms histories in two SEEG rest records
This work used the fixed 24-contact selections, digital arrays, source snapshot, and inherited source extraction code. The source was retrieved and checked again. The new test measures finite-history directed prediction rather than undirected network stability.
- usesIndependent phase controls kept positive median bipolar gamma power correlations between shafts in two SEEG rest records
This work uses its two exact digital crops, fixed metadata contact selection, source receipts, and MIT EDF parser. We checked every crop value against fresh complete EDF downloads. The new endpoint is correlation between window power signals.
