Brain region groups gave no clear gain for joint 4–30 Hz SEEG power forecasts 100–500 ms after pulses at 82 sites in eight people with five fit pulses and Student t models with four degrees of freedom

Brain region groups gave no clear gain over separate shaft scales for joint SEEG log-power forecasts. The test used 4–30 Hz power at 100–500 ms after pulses, five fit pulses per site, and fixed Student t models with four degrees of freedom. It used 82 sites, 546 later pulses, and eight people from OpenNeuro ds004696 version 1.0.1. All models had the same single-shaft forecasts. The mean region gain was −0.000772 nats per shaft. The descriptive 95% person bootstrap interval was −0.005447 to 0.003964. Exact controls covered all 708 group partitions with the same sizes. Region groups beat the mean loss of arbitrary groups, but had no clear gain over their proper density mixture. A similar group pattern occurred before stimulation. The result does not show equivalence or a stimulation-specific effect. The package contains three figures, compact data, all pulse scores and partition densities, code, fixed source versions and hashes, and reproduction instructions. A complete source file was freshly rebuilt. Independent density checks and an exact replay passed.
