After shaft and baseline control, the 95% interval for mean gamma change correlation included zero in 32 ds004100 SEEG patients. Patient sampling assumed independence and exchangeability.

We tested early and later gamma power changes between two numbered seizures at the same bipolar SEEG pairs. SEEG means stereoelectroencephalography. We used 32 patients from public ds004100 version 1.1.3. The early period was the first ten seconds after onset. The later period was 10–30 seconds after seizure end. We controlled for electrode shaft and baseline power change. The mean patient partial correlation was -0.059. Its 95% patient bootstrap interval was -0.172 to 0.052. The interval assumes independent, exchangeable patients. It included zero, but patient estimates ranged from -0.745 to 0.596. The descriptive correlation without baseline control was -0.298. The shared baseline enters the two scores with opposite signs. The comparison shows sensitivity to baseline treatment. The test concerns spatial differences within shafts. It does not measure whole-seizure severity or prove the absence of a relation. All 64 feature files were rebuilt from fixed public source objects. All arrays and 320 raw range hashes matched exactly. Independent covariance, signal decoding, and resampling checks passed. A separate analysis reproduced all six numeric output files byte for byte. The package preserves code, power data, source provenance, uncertainty draws, and reproduction instructions.

    We used its discussion of shared baseline subtraction and linear control in SEEG for scientific context after our plan and numeric analysis. No numeric input or code was reused. Our report identifies the covariance relation as standard algebra.

    We inherited the 32-patient source selection, clinical event rules, public source object pins, and EDF transport and decoding design through the gamma parent. The copied EDF helper identifies this code lineage.

    This publication supplied all 64 gamma power files, clinical metadata, object version pins, headers, and the extraction code. We used these files for a new fixed analysis of changes between two seizures, and rebuilt every feature file from the public source.

    We read its shared versus disjoint baseline gamma result to place the present baseline comparison in context after our plan and numeric analysis. No numeric input or code was reused. The present question uses opposite score signs, bipolar pairs, changes between seizures, and power after seizure end.

    The analysis uses presurgical SEEG recordings and clinical metadata from OpenNeuro ds004100, version 1.1.3; the exact version and CC0 license are recorded in the preserved dataset description.
