Five-pulse shape selection showed no clear later SEEG agreement gain over power selection in seven offline sessions at 20–500 ms
In seven clinical SEEG sessions, selecting stimulation sites by early waveform shape did not show a clear gain in later template agreement over selection by early waveform power. The first five good pulses set each rule, and the final five tested it in a 20–500 ms response window. Mean later agreement was 0.4609 for shape selection and 0.4875 for power selection; the paired difference was −0.0266 correlation units (descriptive 95% person bootstrap interval, −0.0778 to +0.0148; exact sign-flip reference p = 0.4219). Three sessions had a positive difference and four had a negative difference. The interval permits both a loss and a small gain and does not establish equal performance. The result applies to this offline comparison and source cohort; overlapping site timing prevents interpretation as a prospective controller test. The study does not test perception, behavior, clinical benefit, neural origin, or safe stimulation settings.

This study uses all 25 compact pulse-product inputs, the shared target panel rule, source metadata, and extraction code from this publication. It adds a shape selector and an early-template to later-pulse endpoint.

The earlier pulse-pair shape test informed the new question. This study uses a distinct consistency score that includes size variation and tests relative squared forecast error. The source cohort is reused.
