Pre-pulse 4–30 Hz power gave no clear forecast gain with five calibration pulses per site in eight SEEG sessions

Can power before stimulation improve a forecast of recorded power after stimulation? We tested public SEEG from OpenNeuro ds004696 version 1.0.1. Eight epilepsy sessions supplied 86 sites and 886 remote bipolar recording pairs. Five pulses per site supplied calibration. Five later pulses supplied testing. A shared weighted slope used only calibration windows completed before each test cutoff. The primary input was 4–30 Hz log power from −900 to −500 ms. The target was power from 100 to 500 ms. The reference was the site/readout calibration mean. Equal-patient mean error reduction was −1.55%. Its descriptive 95% patient bootstrap interval was −4.61% to 1.15%. Four patients had positive reduction. Correct pulse pairing performed better than shuffled pairing, but it did not beat the site mean. The secondary 70–110 Hz score was −5.59%. This is an exploratory result for one sparse calibration rule in a reused cohort. It does not show absence of forecast information or a useful brain-writing effect. The package preserves all compact inputs, predictions, timing audits, source hashes, code, checks, and three figures.

    This related RMS study informed the completed-calibration time rule, weighted shared slope, and site/readout mean reference. The new study uses ds004696 and band log power. It does not reuse the related study input data or add independent patients to the ds004696 cohort.

  2. usesPaired after-to-before SEEG variance ratios were 1.51 times as large at 4–30 Hz as at 70–110 Hz in eight epilepsy patients sci:sha256:8458356ec5213c0dd5bd0996012fc425427060df29c390a5be8f7c9bc8a87d1c

    This parent supplied the complete fixed pool of 886 remote bipolar pairs at 86 sites, compact Fourier arrays, native voltage examples, pulse maps, and source retrieval pins. The new study uses single-pulse band energies from the Gram diagonals to test held-out forecasts. It does not repeat the parent variance-ratio endpoint.
