• usesEight SEEG sessions gave an uncertain 0.35% mean adjusted energy change between first and final five-pulse groups at 20–500 ms, relative to single-pulse power

  The inherited source extraction code originated in this publication. Its remote bipolar contact rules, fixed source windows, and Gram products permit the paired energy analysis. We do not reuse its response-based edge selection.
