Gap selection gave two fewer later SEEG pulse matches than pair ranking in eight sessions with five calibration pulses, known pulse times, and r ≥ 0.8

This study tested whether five early electrical pulses could select a second SEEG recording pair that filled gaps in the first pair. Both rules used four contacts per site and known pulse times. The data came from OpenNeuro ds004696 version 1.0.1 and eight patient sessions. At r ≥ 0.8 over 20–500 ms, the gap rule gave 273 of 415 later pulse matches. Separate pair ranking gave 275. The equal-patient rates were 67.56% and 67.95%. The difference was −0.38 percentage points; the patient bootstrap 95% interval was −0.96 to 0.00 points. The sign-flip reference gave p = 0.50. The second pair changed at 22 of 83 sites. The early mean maximum correlation increased, but the later mean maximum correlation decreased. The package preserves exact trial products, all choices and pulse outcomes, figures, code, pinned source hashes, and replay instructions. A fresh complete-source extraction for one subject matched the inherited inputs exactly. This test does not establish equivalence, neural origin, live feedback benefit, or performance in a new cohort.
