A SEEG site reader trained on five pulses per target had more gain at 4–30 Hz than at 70–110 Hz in eight patients at 100–500 ms
We tested which frequency band better identified the site of a brain stimulation pulse from one remote bipolar SEEG pair. We used OpenNeuro ds004696 version 1.0.1, with eight patients and 86 sites. Each reader used five early pulses per target for calibration and five separate later pulses for test. Both bands used ten complex coefficients and a fixed nearest mean rule. The after window was 100–500 ms. A separate before-pulse reader measured target information linked to the recording block. Gain is after skill minus before skill. Skill adjusts accuracy for the number of targets. Mean after accuracy was 34.6% at 4–30 Hz and 18.3% at 70–110 Hz. The low band gave 21.3 points more gain on the chance-adjusted skill scale. The 95% patient bootstrap interval was 12.6 to 30.2 points. The contrast was positive in all eight patients. Four planned checks retained a positive mean contrast. The package preserves dataset-derived numerical inputs, fitted readers, predictions, validation records, and three figures. GPL analysis and extraction scripts are omitted, so the package does not permit an exact replay by itself. This is a new reader test in a used cohort. The blocked schedule limits a causal claim. The test does not show transfer to a new session or an online brain interface.

The earlier low versus high frequency forecast result supplied the band hypothesis for this exploratory analysis of the same cohort. This study tests stimulation target identity with a matched feature reader and a before control. It does not supply an independent cohort or establish useful absolute voltage forecasts.

This study uses the archived voltage Fourier coefficients, fixed remote bipolar pair selection, pulse maps, native voltage audit samples, source metadata, and extraction code. Those files define the inputs and permit source checks for the new target identity reader.

[Legacy relation: reproduces] This study uses the exact 97 task definitions, 430 held-out pulse identities, compact coefficient arrays, and source records from this reader study. Independent code reproduces all 17640 primary voltage predictions and all 388 task, band, and state accuracy values.
