A 1 ms endpoint screen changed common-average theta power on unmarked hippocampal contacts in 89 ds004752 v1.0.1 trials

We tested how an endpoint screen changes the shared reference in public SEEG data. The source was ds004752 version 1.0.1. The screen excluded contacts with same-sign endpoint runs of at least 1 ms during late maintenance. We compared the screened common average with the average of all SEEG contacts. Both references evaluated the same unmarked hippocampal contacts and trials. The primary rule found 90 positive trials among 2,561 eligible trials from 14 patients. One trial had no unmarked hippocampal contact. Power changed in the 89 evaluable trials from two patients. For sub-12, the mean signed change was -0.1440 dB. The mean absolute change was 0.4059 dB. Trial means ranged from -4.1979 to +0.6968 dB. The endpoint marker does not establish artifact cause or a better reference. The package preserves all required Fourier data, 14 raw check windows, code, source versions, range hashes, and results. Independent time-domain checks passed. An offline repeat gave identical result files. Fresh selected source requests reproduced all 21 range hashes. Complete source file hash evidence is inherited from the cited census.

    Its trial-deletion sensitivity result motivated a different measured quantity: reference changes within retained trials on the same unmarked hippocampal contacts. We use the report for scope and context, not its result arrays.

    We use its complete endpoint run tables, source headers, metadata, fixed source versions, and full-file hash evidence. They define the window screens and retrieval recipe. Every retrieved parent file passed its archived size and hash checks.

    We read this related phase trial-deletion result after computing our contrasts. Its common-average analysis retains all reference contacts. It establishes the scope distinction from our paired within-window reference-pool change.

  4. usesThe late maintenance hippocampal theta load estimate had a bootstrap interval that included zero after correct responses in 14 patients sci:sha256:f0715b2f4b540f7625d42bad529c99a621eea5726f8bc9f707c778098bc9cc62

    We use its source hippocampal labels, event arrays, timing provenance, and extraction code. Compact original and standard common-average theta values provide validation targets for all 253 fresh windows.
