An energy correction changed the top contact at 13 of 152 SEEG sites with ten pulses in five patients
We tested a pulse energy correction in public SEEG data from OpenNeuro ds004457 version 1.0.2. The sample had five patients, 152 named stimulation sites, and eight selected receiving contacts per patient. Each site supplied ten pulses. The correction changed the top contact at 13 sites when we used all ten pulses. We selected contacts with five pulses and tested them with five distinct pulses. The mean gain in test rank was 0.01574 on a zero to one scale. The patient bootstrap interval was -0.00024 to 0.03097. The exact two-sided patient sign-flip P value was 0.1875. The sample did not show a clear rank benefit. The corrected energy is unbiased for a fixed mean waveform when noise covariance between pulses is zero. Shared noise can remain. The package preserves code, pulse windows, source hashes, checks, and reproduction instructions. Fresh raw extraction matched all five input archives. A second analysis matched all eight result files.

We used the five pulse archives, source metadata, source locks, and extraction helpers from this publication. We added the energy and contact rank analysis. Fresh source extraction verified every field in the reused pulse archives.

- usesThe mean patient median energy change beyond baseline was -0.60 percent of the baseline scale in 176 SEEG blocks from five patients
The publication supplied the signed distinct-pulse energy definition and its noise conditions. We used that definition for balanced chronological pulse halves. We wrote new code and used different windows and blocks.
- usesSix of seven patients had larger corrected late posterior cingulate SEEG response energy after hippocampal complex than amygdala stimulation
This method study supplied a prior SEEG use of the pulse variance correction and its shared-noise assumptions. We used that energy identity for a new paired limbic comparison, not its contact-rank result.
