Late SEEG variance exceeded pre-pulse variance after mean waveform removal in seven selected ds004696 patients

Late SEEG sample variance was higher after stimulation than before stimulation in all seven selected patients. The study used public OpenNeuro ds004696 version 1.0.1 data. It kept 80 stimulation groups and 1,516 contact-group rows, with ten pulses per group. The primary data had a 45 Hz low-pass filter. The time windows were 100 to 500 ms after each pulse and -450 to -50 ms before it. The analysis removed the time mean of each pulse and the mean waveform across pulses. The mean patient contrast was 2.19 dB, with a geometric variance ratio of 1.66. The 95 percent patient bootstrap interval was 1.40 to 3.24 dB. The exact two-sided patient sign flip test gave p = 0.015625 under independent patients and a symmetric zero-null contrast distribution. A template from separate pulses left a 2.04 dB increase after scalar fits. Nearby contact subtraction gave 2.05 dB in an exploratory check. These results describe variable corrected voltage. They do not identify its neural cause. The patient sample and source correction are fixed. The package preserves selected data, code, source records, results, checks, and source retrieval instructions.

usesA bounded shift model reduced the mean relative prediction gap to two free waveforms in seven selected SEEG patients under fixed source correction
This publication supplied the original prepared voltage and source provenance used through the direct input. The present study rebuilt all seven pinned public corrected source objects to check the inherited compact arrays.
usesTwo shared time waveforms gave lower mean 100 to 500 ms prediction loss than one in seven selected limbic SEEG patients under fixed source correction
We used its compact filtered voltage arrays for 80 groups and 1516 contact-group pairs. Fresh pinned source downloads rebuilt all arrays exactly. The new test compares one and two shared time waveforms.

usesTwo free waveforms gave lower mean relative 100 to 500 ms SEEG prediction loss than a fixed derivative model in seven selected patients under fixed source correction
The voltage inputs originated in this publication. We used its filtered pulse arrays and source preparation records, as preserved by the immediate input publication.
usesPost-pulse variation gave lower loss for separate 100 to 500 ms SEEG repeat gaps in seven selected patients after fixed correction and time mean removal
This study uses the selected voltage windows, source Gram matrices, complete source records, and source retrieval code. It adds a forecast loss test with separate four-pulse training and three-pulse test sets. It reuses the same patients.
usesPre-pulse energy had a mean partial rank association of 0.081 with late waveform deviation in seven selected SEEG patients after fixed source correction and pulse number adjustment
This publication supplied the selected voltage windows, source Gram matrices, and fixed selection. It also supplied source text, hashes, and source rebuild code. These inputs enabled a new pulse-wise rank association test. All 190 inherited file sizes and hashes matched. The patient cohort is reused.
uses100–500 ms SEEG energy correlation between shafts exceeded pre-pulse correlation in three of seven selected ds004696 patients after trend removal with assumed source trial order
This work uses the fixed selection, pinned source objects and hashes, archived source Gram matrices, and archived 45 Hz voltage traces. Fresh source energies were checked against those arrays before the new correlation analysis.
