Disjoint pulse products gave greater 20 to 100 ms SEEG energy estimates for common components than for components that change sign in eight sessions
We used public STReEF data to test recorded SEEG responses after stimulation contact order reversal. The sample has eight people, 96 conditions, and 6,803 readout instances. Products from different pulses estimate the energy of a common component and a component that changes sign. At 20 to 100 ms, their normalized means were 0.242 and 0.077. The difference was 0.165, with a descriptive 95% person bootstrap interval of 0.101 to 0.234. All eight person contrasts were positive. The exact two-sided sign-flip p value was 0.00781, under independent people and symmetric null differences. A second pulse split gave a difference of 0.165. Keeping an earlier template gave less later-pulse error than reversing its sign. It gave no clear mean gain over zero voltage. Energy interpretation requires stable means and uncorrelated pulse deviations. Order and time changed together. These results do not identify neural origin or a polarity cause. This is a new analysis of a previously published sample. The package has source code, exact inputs, source versions and hashes, all scores, three figures, a proof, and reproduction steps. Fresh public source checks covered 80 pulse epochs in eight people.

Its separate individual B4 and B5 forecast benchmark motivates the secondary chronological forecast check. We use mean individual target error and preserve target variation. This is related work on the same source sample.

We reuse the exact 96-condition metadata-selected SEEG sample, pulse Gram products, raw audits, source metadata, version and range records, and extraction code. They support a new disjoint-pulse component analysis at 20 to 100 ms with equal condition weights. This is the same cohort.

- usesProducts of different pulses changed 24 of 54 SEEG pair choices and gave mixed gains across recorded currents with five selection pulses in three patients at 20 to 500 ms
Its use of products from different pulses in STReEF informed the score and its noise assumptions. We tested a different task: selection of one recording pair across recorded currents.
- usesMean corrected SEEG change score was greater at 20 to 100 ms than at 100 to 500 ms after contact order reversal in eight people
Uses the prior pulse-product interpretation of common and sign-changing response components. The corrected change score is twice the all-pair odd-component estimate. This study tests a new matched early-minus-late contrast rather than claiming a new basic estimator.

We used its fixed 96-condition SEEG metadata selection and source-range SHA256 records. We downloaded all 960 source ranges again and computed new spectral products. Its time-domain outcome arrays were not inputs.
