Calibration across seven checks reduced before-pulse SEEG calls at 85 selected sites in eight people
We tested repeated reading of public SEEG voltage after stimulation. We used 85 selected sites in eight people from OpenNeuro ds004696 version 1.0.1. Five early pulses fixed each response template and its thresholds. Five later pulses per site supplied 425 after windows and 425 before windows. Seven separate thresholds increased the equal-person before-call rate from 13.98% at one final check to 46.90%. One shared threshold across seven checks reduced it to 17.45%. Relative to separate thresholds, the shared rule reduced after calls by 5.04 percentage points and added 69.62 ms to mean assigned after decision time. All three fixed sensitivity tests kept this tradeoff. Independent score and decision checks passed, and a full repeat gave identical output hashes. The package preserves voltage, code, figures, source checks, and all decisions. This offline result concerns selected pulse windows in reused sessions. It does not prove neural-response labels, a clinical rate guarantee, or a live BCI benefit.

This study motivated calibration across reading times. It tested offline site labels in another SEEG dataset. We measured binary pulse-window calls and assigned time in ds004696.
