An added five-pulse mean gave higher mean 7 Hz phase consistency than later signals at 86 selected SEEG sites
We tested whether an added mean response could reproduce later phase alignment in public SEEG. The test used 86 selected stimulation sites in eight people from OpenNeuro ds004696 v1.0.1. Five early pulses set each mean. Another 612 pulses tested it. At 7 Hz, in a 400 ms window centered at 260 ms, the added reference gave mean pairwise phase consistency of 0.469. Recorded responses gave 0.274. The recorded score minus the reference score was −0.195, with a descriptive 95% person interval of −0.303 to −0.094. All eight person differences were negative. An added early background mean also increased alignment. The package provides a phase-checking tool, voltages, code, source hashes, numeric results, four figures, and replay instructions. The cohort and readout choices were used before. The test does not identify a neural phase reset or a benefit in a live interface.

This prior simulation supplied context on effects of added responses in a phase test. It tested prediction of simulated response size. The current work tests phase consistency in later recorded responses with fixed added-mean controls.

We used its exact processed voltage windows, chronological pulse maps, metadata, and retrieval code. All 16 copied data files match its archive hashes. These inputs enabled the new phase and timing prediction test.

We reused the processed voltage windows, pulse metadata, fixed recording-pair choices, source records, and retrieval code. All 16 input data files matched the parent manifest. We measured later sample variance outside one early shape, after removal of the later group mean.
