A gate based on past voltage raised 4–8 versus 4–10 Hz phase agreement within 45 degrees by 1.73 percentage points in seven SEEG rest records

We tested whether a gate based on past voltage selects later phase targets that agree across theta band definitions. We used seven public SEEG rest records from OpenNeuro ds006065 version 1.0.0. Each record supplied four selected bipolar pairs. A fixed amplitude threshold used early data and a 500 ms past history. Targets were 50 ms later. Centered 2 s filters defined 4–8 and 4–10 Hz phase. Mean agreement within 45 degrees rose from 83.64% at all read points to 85.37% at gated points. The gain was 1.73 percentage points. The gate retained 26.09% of read points. A descriptive person bootstrap gave a 95% interval of 0.61 to 2.84 points. The gate reduced agreement for the planned 5–9 versus 4–10 Hz comparison. Changing the reference to 4–8 Hz changed 16.96% of fixed learned-command success labels. Mean success changed from 51.28% to 50.55%. The package preserves input voltage, models, source hashes, code, results, checks, and four figures. The records and models were reused. These results measure sensitivity to phase definitions. They do not establish a true neural phase or stimulation benefit.
