Equal shaft weights changed top 10 percent SEEG hubs for 1–80 Hz links between named shafts in two 60-second records from each of 36 epilepsy patients

We tested whether target shaft weights change SEEG hub sets. We used two 60-second interictal records from each of 36 epilepsy patients in OpenNeuro ds004100 version 1.1.3. Both scores used absolute Pearson correlation between bipolar channels on different named shafts. The signals, reference, links, and candidate nodes were fixed. Equal shaft weights replaced a mean of 10.75 percent of the top 10 percent hub set at 1–80 Hz. The descriptive 95 percent patient bootstrap interval was 8.40 to 13.26 percent. Mean agreement between records changed by 0.23 percentage points, with an interval of −3.14 to 3.64. Complete uniform duplication of one target shaft left the score with equal shaft weights unchanged. We prove this property under fixed correlations and fixed candidates. These results do not establish clinical accuracy or recovery of unrecorded brain tissue. The package preserves all inputs, code, source pins, hashes, all nine fixed settings, and reproduction instructions.

This publication supplies all 72 contact covariance files, the fixed contact selection, the bipolar pairs, source metadata, and pinned raw retrieval records. We use these inputs to compare channel weights with shaft weights on fixed links between shafts.

The earlier model result informed our limit on the interpretation of hub agreement between records. We do not treat agreement as proof of coupling or clinical accuracy. Its patient data overlap with this study.

usesA twofold target weight range reduced stable 1–80 Hz SEEG shaft leaders from 55% to 25% on average in 36 patients
This study extends the equal channel and equal shaft weight comparison. It tests every positive target shaft weight vector within a stated ratio. The endpoint is a repeat leading channel within each shaft. The patients are the same.
usesLog distance reduced mean test error for absolute 1–80 Hz correlation between bipolar SEEG channels on different shafts in 36 patients with epilepsy
Its study of shaft weights and network hubs guided our use of equal total weight per shaft pair. We also fixed an equal-edge-weight sensitivity before the new signal results.
