Response correlations gave no clear site accuracy gain with five fit pulses per site and four SEEG pairs in eight patients at 50 percent weight

We tested response correlations in eight patients from OpenNeuro STReEF ds005448 v1.0.0. Each patient had four local stimulation sites and four selected recording pairs. Five earlier pulses per site fitted the readers, and five later pulses tested them after recorded contact order reversal. The readers used identical pairs, site means, and marginal feature scales. At 50% correlation weight, correct labels changed from 115 to 116 of 160. The equal-patient mean change was +0.625 percentage points, with a 95% patient bootstrap interval of −1.875 to +3.125 points. Feature-position permutation controls had nearly the same mean accuracy as the fitted correlations. The result gives no clear evidence of a gain from full correlations in this short fitting task and does not establish equal performance. This exploratory analysis reuses a cohort and does not test online brain-computer interface control.

    This work supplied the candidate response features, selected voltage windows, source metadata, range hashes, retrieval code, and license texts. We rebuilt the inputs from pinned public signal ranges before we tested the correlation reader.

    This work supplied the fixed four-site sample, fit-only pair rank, marginal feature scales, and independent-reader design. We reproduced its 115 correct labels from 160 test pulses before we compared full response correlations.

    Its short-fit correlation result informed the question and the matched-scale comparison. It used a different SEEG dataset and a forecasting outcome. It supplied no input data or primary accuracy values for this study.
