Five-pulse Hann forecasts at 100–500 ms had 18.7 points more excess skill at 4–30 Hz than at 70–110 Hz in eight SEEG patients
In eight SEEG patients, a five-pulse mean forecast had more excess skill at 4–30 Hz than at 70–110 Hz. The main test used Hann-tapered voltage at 100–500 ms after a pulse. Skill was 1 minus squared forecast error divided by target energy. Excess skill was the after-pulse score minus the matched before-pulse score. The analysis used 886 remote bipolar pair instances at 86 sites. The first five good pulses fit the mean. The last five good pulses tested it. The paired contrast used site medians and equal patient weights. Its mean was 18.72 percentage points. The descriptive 95% patient bootstrap interval was 11.79 to 26.24 points. The contrast was positive in all eight patients. Mean after-pulse skill was -2.49% in the low band and -18.77% in the high band. Neither band showed a clear mean gain over zero voltage. Fixed control analyses kept a positive mean contrast. A rectangular taper reduced it to 7.55 points. The score separates alignment from template energy cost. The package includes a proof, source code, voltage coefficients, event maps, provenance, figures, and reproduction instructions. All eight complete public derivative files passed their full hashes and reproduced the saved inputs exactly. A second run reproduced all numerical results exactly. This is an exploratory study of a known cohort. It does not establish neural origin or live BCI benefit.

Its signed alignment result in a different SEEG cohort supplies context for the distinction between sign transfer and improvement over zero. The report states that this caution and the squared-error expansion are not new general results. Its numerical input files were not reused.

This study reuses the fixed eligible pair tables, early and later pulse maps, voltage coefficients, native audit voltages, source pins, metadata, and source extraction recipe. It tests the signed early mean on later pulses, rather than variance outside an early response plane.

This study uses the eight-patient coefficient arrays, pair and pulse selection, native audit waveforms, metadata, source hashes, and reconstruction code from this publication. It adds matched early amplitude calibration and tests a fixed real shared-waveform map against a full map on separate later pulses. Its site and patient mean score differs from the earlier pair-median score.

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.
