Mean theta–gamma phase regression depth was lower with a six scaled MAD excursion mask than with shifted masks in 72 short SEEG excerpts from 36 patients

This test used public stereoelectroencephalography (SEEG) data from 36 patients with epilepsy in OpenNeuro ds004100, version 1.1.3. Each patient supplied two 56 second score intervals. The test fitted gamma amplitude from 70–100 Hz to theta phase from 4–8 Hz. A six scaled MAD voltage mask excluded large excursions and 0.25 seconds on each side. Its reference was 19 shifted copies with the same excluded sample count. Mean depth was 0.029291 with the excursion mask and 0.031572 with shifted masks. The paired patient contrast was -0.002281. Its 95 percent patient bootstrap interval was [-0.003537, -0.001333]. The result assumes independent, exchangeable patients for this interval. It measures sensitivity of a fixed score. It does not identify spikes or artifacts. The package preserves code, regression sums, all scores, source versions and hashes, one raw example, and offline and full source instructions.

usesTheta and high gamma amplitude correlation maps had positive mean agreement with voltage, shaft, and power controls in paired 56-second SEEG excerpts from 35 patients
Its voltage excursion screen and shifted-screen check informed our saved method. We tested amplitude to amplitude correlation maps. We did not reuse its phase to amplitude scores.
usesUnscaled theta–gamma phase coefficients raised mean conditional relative squared error in paired SEEG excerpts of 56 seconds from 36 patients
Supplied the 72 phase-regression sum files, source provenance, raw fixture, and extraction code. This study uses those inputs to test coefficient transfer between paired files. It uses the same patient cohort.
