Early bipolar SEEG power did not show a clear decrease within 96 five-pulse blocks from eight patients after correction for power before each pulse
This study tested whether early voltage power decreased within repeated electrical stimulation blocks. It used public SEEG data from OpenNeuro ds005448, version 1.0.0. The fixed sample contained 96 five-pulse blocks from eight patients. The test used remote adjacent contact differences. It compared pulses 4 and 5 with pulses 1 and 2. It used power from 20 to 100 ms after each pulse and corrected for power before each pulse. The mean patient log score was -0.02550. This gives a 2.52% decrease in the corrected power ratio. The 95% patient bootstrap interval ran from -10.54% to +6.58%. The two-sided patient sign-flip test gave p = 0.6016 under a sign-symmetric null model. This sample did not show a clear mean decrease. It does not rule out changes in responsive contacts or selected brain areas. The package contains code, all derived features, fixed source metadata, range hashes, 40 raw examples, and full retrieval instructions. Two fresh extractions agreed for all 480 epochs.

- usesUnder independent pulse errors, a variance correction reduced excess 50 to 250 ms SEEG block disagreement by 37% in eight patients
This work retained the first 12 eligible blocks per patient from the source selection.
- usesBackground forecasts reduced mean scaled error for four SEEG voltage bins at 20–100 ms in eight selected patients with mean removal
The original patient, recording, and first-12-five-pulse-block selection was inherited through the matched-site parent. This study kept those rules and verified them against public metadata.
- usesNine pooled pulses gave less mean SEEG prediction error than four same-order pulses in eight patients
Used its cohort selection, public source versions, byte hashes, and metadata through the input publication. These pins allowed fresh retrieval of all 460 pulse epochs and exact reconstruction of the input arrays.
- usesSample mean removal lowered the 100–300 ms SEEG power-ratio score in eight patients after window mean removal
This study used the earlier patient and block selection. It also used the source metadata, retrieval code, range hashes, and 40 raw epoch examples. It retrieved all 480 epochs again and tested a different power measure in the same cohort.
- usesA variance rule reduced 50 to 250 ms SEEG prediction error in seven of eight patients across reversed contact orders
The matched-cohort input inherited the first 12 eligible five-pulse blocks per patient and source object pins from this work. The present study kept those rules and used the 92 matched blocks. It did not select sites from their response size.
- usesSEEG waveform agreement across reversed contact orders increased after pulses in eight patients for 20–100 ms windows with mean removal
This study used the fixed eight-patient cohort and first 12 eligible five-pulse blocks per patient. It used the source selection, fixed object versions, byte range hashes, and 40 raw epochs. It independently checked the selected blocks against source metadata. It matched reversed contact orders and calculated new signed waveform scores.
- usesWith equal pair weights and mean removal, templates at half amplitude had lower 20–100 ms SEEG prediction loss than pooled templates in eight patients
The direct source retained this publication's first 12 eligible five-pulse blocks per SEEG patient. The present test retains that block selection and verifies it from the preserved event tables.
