Early speech contrast selection did not establish positive shared later 65 to 115 Hz SEEG power changes after block mean removal in 16 patients during one film under cyclic shift assumptions

We tested shared later power changes in 16 SEEG patients who watched one film. We used public OpenNeuro ds003688, version 1.0.7. We selected one contact pair per patient from six early film blocks. We tested 156 later one-second windows per patient. The band was 65 to 115 Hz, with 98 to 102 Hz removed. We removed each patient's mean separately in every test block. The mean of 120 dependent patient-pair correlations was -0.01095. A one-sided test with 19,999 within-block cyclic shifts gave p = 0.93115. The descriptive patient bootstrap interval was -0.03604 to 0.01536. The test did not establish positive shared changes. It did not show that the effect was zero. The null test assumes cyclic shift invariance of the later signals, conditional on early selection. The scope is these selected pairs and later sections of one film. The package stores code, all candidate features, selected raw signals, source records, results, and repeat instructions. Independent calculations and fresh pinned source samples check the inputs and results.
