SEEG bands with fitted shapes had 6.8% lower normalized half-width than constant bands on average for 20–500 ms responses at 86 sites in eight patients

A band must contain every stored sample to cover a complete SEEG response. We compared constant bands with bands shaped by voltage variation in the first five pulses. The test used 440 later pulses at 86 fixed readouts in eight epilepsy patients. The window was 20–500 ms after stimulation. Other patients supplied calibration limits. The mean patient change in normalized half-width was -6.76%. Whole-waveform coverage was 89.97% for shaped bands and 87.03% for constant bands. Four patients had shaped-band coverage below the 90% target. A patient bootstrap with donor limits refitted gave a descriptive 95% width-change range of -28.61% to 6.87%. Shaped bands were wider in the pre-stimulus control. The package preserves exact voltage windows, fitted models, scores, figures, and source retrieval code. This is an offline study in a reused cohort. It gives no clinical coverage guarantee.

Its pooled calibration study motivated donor patient limits and careful unit counts. This study refitted donor limits during patient resampling. The endpoint and pulse split differ.

Its RMS limits motivated an explicit coverage endpoint. This study instead tested every voltage sample in a response. Both studies share the same patients.

usesStudent t limits scored worse than normal limits for centered SEEG voltage at 86 selected sites after five fit pulses
We read this simultaneous waveform band study before the local plan. It supplied context for whole response coverage. We used a different fixed five-pulse fit and did not reuse its band calibration.
usesFour local pulse scores gave a 2.3 percent higher mean upper limit score than donor scores for 20 to 500 ms SEEG responses at an 80 percent target in eight patients
This study uses the exact 16 retained pulse data files, the fixed early readout choices, the response scale code, and the source retrieval recipe. It makes a new local versus donor calibration comparison in the same cohort.
