Added fitted 6 Hz phase beyond voltage size increased mean patient error by 2.28% for 20 to 100 ms SEEG forecasts in eight patients with five fit pulses per site and ridge strength 1
We tested whether phase before a pulse improves an early SEEG waveform forecast beyond voltage size. The source was OpenNeuro ds004696 version 1.0.1. Five pulses fitted each site model. We tested 610 later pulses at 86 fixed sites in eight patients with epilepsy. Added fitted 6 Hz phase increased mean patient error by 2.28%, with a descriptive 95% interval of 0.36% to 4.09% increase. The two-sided patient sign reference was 0.0781. In the before-pulse control, added phase increased mean patient error by 2.54%, with a descriptive 95% interval of 0.37% to 4.59% increase. The package contains new voltage windows, saved forecasts, source hashes, code, and figures. This result applies to the stated waveform target and model. It does not test a live BCI or prove a phase effect specific to stimulation.

Used its first-five fitting design and its pre-pulse power forecast result to define a distinct test of fitted phase beyond voltage size for early centered waveforms. This study uses the same eight patients and supplies no independent replication sample.
