FRandR map changes exceeded event and 30-second block exchange controls in seven patients with five-minute sleep SEEG records
We tested whether a fixed spatial event map could explain repeated five-minute sleep SEEG records. FRandR means a fast ripple that overlaps a ripple. OpenNeuro ds003498, version 1.0.1, supplied 135 records and 23,528 FRandR marks from seven patients with depth electrodes. Each patient rejected a fixed map under independent event allocation with exact record and channel totals. Each patient also rejected the planned 10-second and 30-second block exchange controls. Each test family used Holm correction. A post hoc block control kept exact event totals and gave the same rejection count. Under independent event marks, the median corrected fraction of squared map distance was 72.5%. One patient had a stable leading channel in all records while its full event-share map changed. A three-event record strongly affected one corrected fraction. The evidence applies to the tested exchange models. It does not identify neural causes or surgical accuracy. The package preserves source marks, code, hashes, plans, proofs, count arrays, null statistics, figures, and reproduction checks.

- usesMean 150-second FRandR list overlap was higher within than between sleep SEEG records in seven patients
We used its fixed-map and block exchange results to describe prior evidence for record map changes in the same cohort. This study tests a within-minus-between list overlap contrast. No prior effect estimates were inputs to the new calculation.
- usesEqual recording weights reduced FRandR map loss on later dates in three of seven sleep SEEG patients with a fixed 1 percent uniform mixture
This publication supplied the unchanged source tables, source hash manifest, retrieval code, and implant-type audit. These files enabled the new map weighting comparison. Its within-cohort map variation result informed the local plan. We verified all source files with a fresh pinned public download.
