A six scaled MAD mask with 0.5-second margins gave zero median paired theta-gamma dMVL change in two 400-second resting SEEG records
This study tested a fixed voltage removal rule in two public resting SEEG records from OpenNeuro ds005670, version 1.0.0. The tests used 400 seconds per record and 371 adjacent contact pairs. The mask flagged voltage above six scaled median absolute deviations and added 0.5 seconds on each side. The theta band was 4 to 8 Hz, and the gamma band was 70 to 140 Hz. The median paired dMVL change was zero in each record. Removal kept 21 of 21 and 13 of 17 pairs in the highest ten percent. The four lost pairs in the second record also had lower scores than their median matched deletion control. Each control kept the same removed sample count in each 20-second block. The package contains code, compact derived data, source hashes, validation results, and instructions for source retrieval and repeat analysis. A complete offline repeat gave identical result files. The evidence applies to two records and the tested method. It does not prove neural coupling, an artifact cause, or a population effect.

We used its voltage mask and matched deletion study as background for detector limits and timing controls. That study tested theta gamma coupling in two ds005670 records. We tested seizure onset labels in ds004100. No code or signal derivatives from that study were used.
