Independent output phases reduced 13 to 30 Hz test rejection at shared bipolar SEEG edges under independent contact phases in eight recordings
We tested phase controls for band-integrated imaginary coherency with public SEEG spectra from eight participants. The probes had independent contact phases. At shared bipolar edges, contact controls rejected 5.16% of probes. Independent output phases rejected 2.37%. The difference was -2.79 percentage points. A variance proof explains the effect of a shared contact. The package includes all compact inputs, test rows, code, and source retrieval instructions. The result applies to this phase model and statistic. It does not identify neural connections.
