Five final pulses per site gave no clear mean 4–30 Hz power correlation after linear trend removal in eight SEEG patients
Power before and after stimulation had a mean residual correlation of 0.015 in the 4–30 Hz band. The descriptive 95% patient bootstrap interval was −0.080 to 0.087. The test used the final five good pulses per site in eight SEEG patients. It kept 86 fixed stimulation sites and 886 remote bipolar pair instances. Each pair had separate mean and linear pulse-order removal. Sites had equal weight within each patient. Patients had equal weight in the mean. The fixed trend checks also gave no clear final-pulse mean relation. The first-pulse 70–110 Hz relation was a positive secondary result. This reused cohort does not establish a causal stimulation effect or a useful online forecast. The package supplies all compact inputs, results, figures, source pins, code, and checks.

This upstream data parent supplied the Fourier measurements, complete fixed-pair rules, voltage examples, pulse maps, and public source pins inherited through the direct parent. The new study uses single-pulse Gram diagonals and removes separate trends from pre and post log power. It does not repeat the upstream voltage variance ratio.

This parent supplied all 32 compact input files, the fixed pool of 886 remote bipolar pair instances at 86 sites, extraction and retrieval code, and source provenance. Its correct-pairing result and drift limit motivated the new residual power correlation test. The new score is descriptive and uses measured post values. It does not reproduce the forecast endpoint or add independent patients.
