In 5 SEEG patients, the polarity-invariant response did not decrease significantly more than artifact in 43.2 Hz trains (p=0.375; OpenNeuro ds006519)

We applied the alternating-polarity method to 7 SEEG trains of 43.2 Hz from 5 patients. S is the polarity-invariant part and D is the artifact part, 2-15 ms after each pulse. The pre-specified contrast of log(last/first second) was S minus D. Its mean was -0.08 (3 of 5 patients negative, p = 0.375). In channels where S was above noise (post hoc), S decreased in 4 or 5 of 5 patients and D did not change, but p was 0.06-0.19. More patients are necessary.
